How Long Will It Take for My Hair to Grow Back?
One of the most common questions we hear. The honest answer depends on why it changed in the first place.
Hair Growth Hair Loss Hair Health

How long it takes for hair to grow back depends on why it changed in the first place. After hair loss, breakage, a big cut, or a fringe you have grown out of, the question is almost always the same: will it come back, and how long will it take?

Most people asking this question are going to get a positive answer. Hair is remarkably resilient. Understanding how it grows helps you understand what to expect and why patience is almost always the right approach.

How hair actually grows

Each hair on your head goes through its own growth cycle. The active growth phase, called the anagen phase, lasts anywhere from two to seven years depending on your genetics. During this time the hair grows roughly half an inch a month, or around six inches a year.

If your growth phase runs closer to seven years, your hair has the potential to grow very long before it naturally sheds and regrows. A shorter growth phase of around two years means your hair may reach a natural stopping point, often around the jawline or shoulders, even when it is perfectly healthy. Neither is better or worse. It is simply how your hair is built.

A useful way to think about it
The average head has 100,000 to 150,000 hairs, each growing around 0.2cm a day. Per strand that sounds slow, but across the whole head it adds up to over 36 metres of total hair growth in a single day. It is constant, just not immediately visible.

Why it feels slow at first

Hair grows from the root, not the ends. This means in the early weeks of regrowth you will not see much visible change, even though growth is happening. New hair has to travel a certain distance before it becomes noticeable at the surface.

People with fringes often notice hair growing back faster because it reaches their eyes. Length growth is harder to perceive because there is no equivalent reference point. The hair is growing. You simply cannot see it yet.

What affects how quickly hair grows back

The speed and quality of regrowth depends largely on what caused the change in the first place.

Common causes and what to expect
Breakage. Hair that has snapped from heat damage, colour or tension is not lost from the follicle. The follicle is still active and producing hair. Regrowth is usually straightforward once the cause is addressed.
Stress-related shedding. Telogen effluvium, the most common cause of sudden increased shedding, is temporary. Hair typically begins recovering three to six months after the trigger passes.
Postpartum shedding. Almost always recovers fully within six to twelve months. The shedding is caused by hormonal shifts after birth, not permanent follicle damage.
Illness or medication. Hair often recovers well once health stabilises, though the timeline varies depending on the condition and how long it was present.
A significant haircut. Simply a matter of time and the length of your individual growth phase. Around six inches a year is the average, though some people grow faster or slower.

What helps while hair is growing back

You cannot dramatically speed up hair growth. What you can do is create the best possible conditions for the growth that is already happening.

What actually makes a difference
Scalp health. A healthy, clean scalp supports stronger regrowth. Remove product buildup, avoid harsh shampoos and consider a targeted scalp treatment if needed.
Reducing tension and heat. Less daily stress on the hair means less breakage, which means visible length is retained better over time.
Nutrition. Protein, iron, zinc and vitamin D all support healthy hair growth. If you have been through a period of significant dietary change, addressing that will help.
Regular trims. This one surprises people, but keeping the shape tidy every six to eight weeks prevents the ends from fraying and weighing the hair down. Growth looks faster when the hair does not feel tired.
“Hair growth is slow, but it is steady. If the cause is temporary, hair almost always recovers. Knowing what is happening is the key to getting the best out of what you have.”
Noel Halligan  ·  NOCO Hair Bristol

When hair may not grow back fully

For most people, hair does recover well. There are some situations where the picture is more complex. Genetic thinning, certain hormonal conditions and some longer-term health issues can affect follicle activity over time. Even in these cases, early assessment and the right support can slow the process significantly and improve the quality of what remains.

The most important thing in any case is understanding what is actually happening rather than guessing. A professional can usually identify whether you are dealing with temporary shedding, breakage or something that needs a more structured approach.

Am I Too Old to Visit Your Salon?
No. And if you are asking that question, you are probably exactly the kind of client we love working with most.
All Ages Confidence Inclusive

We get asked this more than you might think. Not just by older clients, but by anyone who has ever felt that a particular salon was not quite for them. Too trendy. Too young. Too intimidating. The honest answer is no, you are not too old. And the question itself tells us something important about what salons have often got wrong.

NOCO is a consultation-led salon. That means before we do anything, we sit down and understand your hair, your life and what you actually want. The result is always personal to you, not to what is trending on Instagram this week.

What age has to do with hair

Hair changes as we get older. It gets finer. It loses density. Grey comes in. The texture shifts. These are real changes and they affect what works and what does not. But none of them mean you should stop caring about your hair or stop coming to a salon. They just mean the conversation needs to be more informed.

A good stylist understands how ageing affects hair and works with it rather than against it. The right cut for finer hair is different from the right cut for thick hair. The right colour approach for someone with a lot of grey is different from someone with a dark base. None of this is complicated once you understand the principles.

“The clients who ask if they are too old are almost always the ones who appreciate the most what a proper consultation can do. They have usually been let down somewhere before.”

What we actually do for clients as hair changes

How we approach ageing hair
Cuts designed for finer hair. As hair loses density, the shape of the cut becomes more important than the length. The Vitality Cut and Clifton Cut are both designed to maximise movement and volume on finer hair.
Colour that works with grey, not against it. Grey is not a problem to be fixed. It is a canvas. Whether you want to blend it, embrace it or enhance it, there is a colour approach that works beautifully for your specific mix of natural and grey hair.
Condition and scalp work. Older hair often needs more moisture and scalp support. We factor this into every service and our homecare recommendations are always specific to what your hair actually needs.
Honest conversation. We tell you what your hair can realistically achieve. Not what you want to hear, but what will actually make a difference. That is what a proper consultation is for.
A note on grey hair
Going grey is one of the most common reasons people feel uncertain about visiting a salon. Whether you want to grow it out gracefully, blend it gradually or cover it completely, there is no wrong answer. What matters is that the approach is designed for your hair specifically and not just a formula applied to everyone.

Who comes to NOCO

Our clients range from students to grandparents. We have people in their twenties coming in for their first proper colour consultation and people in their seventies coming in for a cut they have never quite been able to get right anywhere else. The common thread is not age. It is that they want to understand their hair and leave feeling better than when they arrived.

The question behind the question

When someone asks if they are too old for our salon, what they are usually really asking is: will I feel welcome here? Will someone take my hair seriously? Will I leave feeling like myself, or will I leave with something that does not suit me?

The answer to all of those is yes, yes and no. We take every client seriously regardless of age. The consultation is the same whether you are twenty-five or seventy-five. We diagnose before we design. We listen before we cut. And we do not hand you a style that works for someone else and hope for the best.

How Often Should I Get My Hair Cut?
There is no single answer. It depends on your length, texture and how much your hair goes through. Here is how to work it out for your hair specifically.
Haircuts Hair Health Timing

How often you should get your hair cut depends on your hair length, texture, how much heat or chemical processing it goes through, and what you are trying to achieve. For most people, somewhere between every six and twelve weeks is the right range, but the right answer for you sits within that depending on your specific situation.

The most important reason to keep up with regular cuts is not style. It is health. Split ends left unchecked travel up the hair shaft, causing frizz, breakage and dullness that no product can fully reverse.

Why haircut timing matters

Hair grows roughly half an inch a month. For short or layered styles, that growth quickly changes the shape and balance of the cut. For longer hair, the ends are the oldest and most vulnerable part of the hair shaft, and they accumulate damage over time from heat, styling and environmental exposure.

A regular cut removes that damage before it spreads. It also keeps your style looking intentional rather than grown out.

Signs it is already time
Coarse texture, difficulty styling as usual, visible split ends, ends that appear lighter than the rest of the hair, increased frizz, or hair that tangles more than usual are all signals that a cut is overdue.

How often by hair type and length

Cut frequency guide
Very short or cropped styles. Every four to six weeks. An extra inch on a pixie cut or tight crop changes the shape significantly. Dead ends around the face are also immediately visible at this length.
Layered hair. Every six weeks. Layers grow out quickly and lose their framing quality. The puffed effect of damaged ends is also more obvious on layered lengths.
Chemically treated or frequently heat styled hair. Every six to eight weeks. Processed hair is more prone to split ends appearing sooner after a cut.
Mid-length to long straight or wavy hair. Every eight to twelve weeks. The longer the hair, the further split ends can travel before they become visible, but this also means the damage is building for longer between cuts.
Natural curly or coily hair. Around twelve weeks as a general guide. Curly hair tends to grow more slowly and the curl pattern disguises split ends for longer. Thinner curls or chemically relaxed hair may need to come in closer to eight weeks.
Thin hair. Every six to eight weeks. Thin hair breaks and splits more easily. Regular trims also remove dead weight from the ends, making the hair appear fuller and reducing the risk of further breakage.

Precision cuts maintained regularly always look intentional.

What about fringes?

Most people trim their fringe roughly every four weeks, or whenever it reaches a length that bothers them. Because the fringe sits directly in the line of sight, it is easier to spot when it needs attention than the ends of the rest of your hair. Many clients manage this themselves between appointments, which is perfectly fine with the right scissors and a steady hand.

What if you are growing your hair out?

Trimming while growing your hair is not counterproductive. It feels that way, but leaving split ends to travel up the shaft costs you more length than the trim does. Even when growing, having a small amount taken off every three months keeps the ends healthy and means the length you are growing is retained rather than breaking off.

Ask your stylist specifically to maintain the length while removing damage. A good stylist will take the minimum necessary to keep the ends healthy without sacrificing length unnecessarily.

5 Hair Care Tips for Curls
Curly hair needs a different approach. These five things make the most consistent difference.
Curly Hair Frizz Moisture

Curly hair is not difficult to look after. It is just different. The routines and products that work perfectly on straight hair can actively damage curly hair. Once you understand why, getting consistently good results becomes a lot more straightforward.

Every curl type behaves slightly differently, so some trial and error is part of the process. But these five principles apply across the board.

1. Get into a washing routine that suits curls

Natural oils produced by the scalp are essential for healthy, hydrated hair. The problem is that curly and textured hair makes it much harder for these oils to travel down the hair shaft due to its shape. This means curly hair dries out faster and is more sensitive to over-washing than straight hair.

Washing once a week or even less is the general recommendation for curly hair. When you do shampoo, focus on the scalp rather than working the shampoo through the lengths. The ends will get cleaned when you rinse. Shampooing the full length too frequently strips the moisture that curly hair needs most.

Healthy curl definition comes from consistent moisture, not product volume.

The sebum problem
Straight hair is easily coated in natural oils. Curly hair, because of its shape, makes this much harder. This is why curly hair gets drier faster and why washing frequency needs to be lower than for straight hair. It is not a hygiene issue. It is physics.

2. Moisturise consistently

Whatever type of curl you have, whether wavy, loose, tight or coiled, curly hair is naturally prone to dryness, frizz and breakage. The solution is not more product. It is the right product used consistently.

What curly hair actually needs
Leave-in conditioner. Applied to wet hair once or twice a week, this provides a sustained moisture boost and helps keep curl definition between washes.
Moisturising oils. Applied to dry hair only. On wet hair they sit on the surface and do not absorb. On dry hair they seal in moisture and keep frizzy ends at bay.
Protein treatments. Help keep curls defined and strengthen the hair structure. Particularly important if you colour or heat style regularly. Protein works alongside moisture, not instead of it.

Nutrition also plays a role. Protein, iron and vitamins that support hair growth and condition come from what you eat as much as what you apply. Read more in our guide on how diet affects hair health.

3. Choose the right products

The curly hair product market is overwhelming. Most of it is not worth the price. A few simple rules cut through the noise.

What to look for and what to avoid
Avoid sulphates and silicones. Sulphates strip natural oils aggressively. Silicones coat the hair and build up over time, blocking moisture from getting in. Look for products labelled sulphate and silicone free.
Choose lightweight formulas. Curly hair needs several different products for different purposes. If each one is heavy, the combined weight pulls curls down and makes the hair look greasy faster, leading to more washing and more dryness.
Match the product to your curl type. Tight coils need different formulas from loose waves. Check the description before buying and read reviews from people with a similar curl pattern to yours.

4. Style correctly

Styling rules that make a real difference
Brush only when wet. Brushing dry curly hair causes frizz that no product can fix. Always detangle when wet, working from the ends upward with a wide-tooth comb.
Apply products immediately after washing. Once the hair starts to dry without product, the curl pattern sets. Products applied too late sit on top of the hair rather than absorbing, leaving a crunchy texture.
Use a diffuser when drying. A standard hairdryer concentrates heat that disrupts curl pattern and causes frizz. A diffuser spreads the airflow and allows curls to dry more naturally. Tip the head upside down to add volume at the root.
Scrunch, do not rub. Rubbing separates curls and causes breakage. Scrunching encourages curl definition, adds bounce and does not disrupt the curl pattern.
“Curly hair is not high maintenance. It just needs the right routine. Once you have that, it looks after itself.”
Noel Halligan  ·  NOCO Hair Bristol

5. Protect your curls overnight and day to day

Protection habits that compound over time
Swap cotton pillowcases for silk. Cotton absorbs your hair’s natural oils and creates friction that causes frizz and breakage overnight. Silk reduces friction significantly and does not strip moisture.
Try the pineapple method. If silk bedding is not practical, gathering the hair loosely at the top of the head before sleep protects the curl pattern and reduces frizz without the need for restyling in the morning.
Use a microfibre towel or a cotton t-shirt. Regular cotton towels absorb moisture aggressively and create friction. A microfibre towel or a soft t-shirt used to gently scrunch out excess water is significantly gentler on curl definition.
Switch to no-crease hair bands. Standard elastics cause breakage and leave a crimp in the curl pattern. Spiral no-crease bands or scrunchies are much gentler and do not leave a mark.

The days become longer and brighter, which can only mean one thing: summer is here! Although summer means beach days and holidays, it’s important to know the dangers of those UV rays.  

You wouldn’t step out into the summer sun without lathering up in sun cream, so why forget about those luscious locks?  

Just like your skin, the sun will damage your hair too. Between sun, sea, and sand, your hair goes through a lot in those summer months. Without the correct hair care steps, the damage can really take a toll on your tresses. Read on to learn how to maintain healthy hair in the summer.  

How sun can damage your hair  

Those hot days and UV rays can be very damaging to your hair. It is crucial to understand those effects and the importance of protecting your hair from the sun.  

  • Cuticle damage – The cuticle is the outer layer of hair protecting the inside of the hair shaft from damage. The UV rays can break this down, causing your hair to dry out, your hair will then attract humidity and humidity means … FRIZZ!  
  • Inner damage – The sun weakens the internal structure of your hair and makes it prone to breakage and split ends. 
  • Colour damage – Coloured hair is even more prone to sun damage. Colour treatments can already leave your hair dehydrated, and too much sun can leave it even more vulnerable to damage. Not to mention – the UV rays perform as a bleach which will slowly but surely fade any colour. Some more colour treatment tips to come… 
  • Water damage - There is nothing like a dip in the pool or a splash around in the sea during those hot summer months! However, sometimes the things we love hurt us the most…  

While you’re splashing about in the pool, chlorine is stripping natural oils from your hair, making your hair dry and weak. This can lead to breakages.  

Salt water can have very similar effects to chlorine water, minus the chemicals. Salt water strips the hair of moisture, making it dry and more susceptible to breakages and split ends.  

How to know if your hair is sun damaged 

Exposure to sun for a longer period of time will make changes to your hair more noticeable. Signs of damaged hair are: 

Split ends – the heat stripping your hair of moisture will make it more prone to split ends and breakages. 

Texture – being in the sun or the pool will strip your hair of its natural oils, causing it to become much more dryer and brittle. So, say goodbye to your silky-smooth hair. 

Discolouration– UV rays react with the melanin in your hair, causing pigment changes. The chemicals in chlorine can also react with your hair – especially if it’s dyed! – altering the colour.

Tips and tricks you need to know to keep your hair healthy in that summer heat 

Start with a summer trim  

It is important to give your hair a head start for summer. Visiting your salon and getting rid of those split ends will keep your hair healthy and easy to maintain in those hot summer months.  

Mask the Mane 

One of the obvious and simple answers to protect your hair from the sun is wearing a hat or a scarf. Wearing a hat or a scarf act as a physical barrier to protect from those harsh UV rays!  

UV protection  

The first thing you do if you know you are going to be spending a day in the sun is lather up your sun cream so why not use the same protection for your hair. UV hair protectants come in all shapes and sizes, from gel to powder. Research the best product to protect your locks! 

Hydration  

This is a tip you really shouldn’t ignore. You could be doing everything right to keep your tresses intact but, without correct hydration, your hair will start to show signs of stress. Drinking water will not only provide hydration for your body but to your hair strands too! 

Keep away from heat styling tools 

With the sun already scorching your strands, using straighteners, curling irons or hair dryers will add to the heat damage. Try using more natural methods of styling your hair in the summertime. Air drying and braids will be your best friend. 

Washing your hair  

It is likely that you will be washing your hair more frequently to help combat the dirt and sweat.  

However, beware of the fact that overly washing and shampooing your hair will strip any natural oils, therefore further drying your hair out!  

Try washing your hair 2-3 times a week and switching out your shampoo and conditioner routine for a more moisturising option. This will help with locking in any moisture in these drying months.  

A pro tip from us this summer is to rinse your hair with cold water after you wash your hair for maximum shine. This is because it will close the hair cuticle and allow the hair to reflect more light.  

Treatments  

Hair masks and leave-in conditioners will help you with adding that extra bit of moisture. Using moisturising treatments will add an extra layer of protection from those UV rays, making it harder for the sun to damage your hair.  

This tip is key if you are in and out of the water! Fully saturating your hair before diving into the pool will lock in that moisture it needs after sun exposure. Note that already wet hair won’t absorb as much saltwater or chlorine chemicals. 

Fight the frizz 

In the heat and humidity, frizzy hair will be your worst enemy. Keeping your hair healthy and well maintained will help keep your frizz to a minimum. Keep your eye out for shampoos and conditioners with two ingredients: amino-silicones, and cationic surfactants, these two ingredients will help neutralise your hair and prevent the humidity from winning this round! 

If the frizz is getting the best of you this summer, here at NOCO we offer Phrizzy-o-therapy treatment to help combat the humidity. 

Colour care 

Coloured hair is already tricky to maintain, let alone adding those summer elements into the mix. If you have coloured hair, exposure to the sun can have many negative effects on your tresses.  

Chlorine chemicals can strip out the colour your hair is dyed and often turn the dye brassy or faded. Ensure you are using colour preserving hair care products during the hot summer months.  

Dyed hair is a lot more prone to dryness as the strands are already stripped of natural oils more than undyed hair. Using hydrating products is your only answer at this time of year; don’t let your hair damage ruin your time in the sun.

 

There you have it … 

Understanding the importance of hair care is vital during these summer months! Stick to our useful haircare tips for summer and help protect your hair. 

Here at NOCO, we are here to help you with any hair care needs, whether you are wanting your start of summer trim or a deep conditioning treatment to help bring back your shine.

Where it started

The Care with Hair campaign grew from a single moment that changed how we think about what we do.

Years ago, I was invited to give a final haircut to one of my clients, Megan, in hospice care. That visit stayed with me. It revealed something that is easy to forget in the day-to-day of running a salon: that a haircut is not just about how someone looks. It is about how they feel. Seen. Cared for. Present.

That one act of compassion became the foundation for everything Care with Hair has grown into. What started as a personal response to a profound moment has become an annual commitment to the people of Bristol who need it most.

“When times are hard, it is easy to focus on numbers and profit. But we have learned that when you focus on people first, everything else follows.”
Noel Halligan  ·  Co-founder, NOCO Hair Bristol

What Care with Hair is for

The campaign exists to help people feel confident, cared for and seen, particularly during difficult times. Recipients have included people going through cancer treatment and hair loss, people in recovery, and volunteers who spend their lives putting others first.

Who the vouchers support
People going through illness, including cancer treatment and hair loss
People experiencing hardship or recovery
Outstanding volunteers nominated by local charities
Anyone a participating charity believes deserves to feel valued and cared for

A haircut has real power
A haircut has the power to change how someone feels about themselves. For someone who has been through illness, difficulty or simply feels invisible, walking out of a salon feeling lighter and brighter is not a small thing. That is what this campaign is about.

Will Bleach Damage My Hair?
The honest answer is yes, to some degree. The better question is how much, and how to keep that to a minimum.
Bleach Blonde Hair Hair Condition

Bleach will always have some effect on hair structure. That is simply how the chemistry works. The question is not whether bleach causes damage at all, but how much, how it is managed, and whether the hair you have can handle what you are asking it to do.

Most problems with bleach happen either at home or when the condition of the hair is not properly assessed before the service begins. Both are avoidable with the right approach.

What bleach actually does to hair

Bleach works by opening the outer cuticle of the hair shaft and reacting with the melanin inside. This oxidises the pigment, effectively removing the colour. The melanin is not removed from the hair; it is rendered colourless.

Once the natural pigment is lifted, what remains is the underlying pigment of the hair. Darker bases reveal red tones first, then orange, then yellow as they lift higher. A pre-lightener lifts this underlying pigment out. A toner is then used to neutralise the remaining warmth and achieve the finished colour.

Why toners fade
Toners sit on the outside of the hair and fade with washing over time. As they fade, the underlying warmth comes back through. This is why toning shampoos and regular gloss treatments are part of maintaining blonde hair, not optional extras.

Breakage versus hair loss

Bleach does not typically cause hair loss from the follicle. What it causes is breakage, and the two are frequently confused. Hair loss means the follicle is shedding. Breakage means the hair shaft is snapping at some point along its length.

There are two types of structural damage to understand. Porous hair has damage to the cuticle, the outer layer. It feels dry and lacks moisture, usually caused by heat. Sensitised hair has damage to the internal structure, which changes the elasticity. Sensitised hair either snaps immediately when stretched or stretches too far and does not return, like chewing gum. Both need to be identified before any bleach service proceeds.

Signs the hair is not ready for bleach
Stretches and does not return. Indicates sensitised hair with compromised internal structure. Bleaching at this point risks further breakage.
Snaps immediately when stretched. Indicates dry, brittle hair with poor elasticity. Needs protein and moisture work before any chemical service.
Feels rough, dry or porous. The cuticle is open and damaged. Bleach on porous hair lifts unevenly and unpredictably.
Previously over-lightened. Hair that has already been pushed to white or near-white has compromised internal structure. Further bleaching without significant recovery time risks irreversible damage.

Going from dark to blonde

Moving from a dark base to a light blonde in a single session is not possible safely. Each bleach application lifts the hair a certain number of levels depending on the strength used, the development time and the starting condition of the hair. Attempting too much lift in one session risks over-processing, which in serious cases means the hair loses structural integrity entirely.

The right approach is to lift in stages with recovery time between sessions. After the first application, a toner is used to improve the result while the hair recovers. A minimum of two weeks is needed before assessing whether the hair is strong enough to go again. This process takes longer than clients sometimes want, but the alternative is compromised hair that cannot be repaired, only cut off.

“When we treat hair, maintaining its condition is the priority. We do not carry out treatments that cause long-term damage to get a short-term result.”
Noel Halligan  ·  NOCO Hair Bristol

Why home bleach is higher risk

Home bleach products are formulated for maximum lift because they are designed as a one-formula-fits-all solution. They cannot be adjusted for your specific hair condition, history or starting point. A professional mixes a bespoke formula based on your natural colour, previous colour history and current condition, then monitors the development in real time.

The other risk with home bleach is timing. The formula cannot tell you when to stop. Leaving bleach on too long causes accelerated damage and in extreme cases the hair structure can break down completely at the root and ends. At the salon this is prevented by ongoing visual and tactile assessment throughout the development process.

How to maintain bleached hair properly

What bleached hair actually needs
A shampoo and conditioner for chemically treated hair. Standard shampoos can strip colour and moisture. A formula designed for bleached or colour-treated hair protects the cuticle and extends the result.
Toning shampoo once or twice a week. Purple or blue toning shampoo neutralises brassiness as the toner fades. This is standard maintenance for blonde hair, not a treatment for a problem.
Regular protein treatments. Bleach reduces the natural protein in the hair. Bond-building treatments such as Olaplex or a Kérastase masque used weekly help rebuild structural integrity between appointments.
Reduced heat styling. Bleached hair is more vulnerable to heat damage than unprocessed hair. Lower temperatures and a heat protector applied before any heat tool significantly reduce ongoing damage.
Careful handling when wet. Hair is always most vulnerable when wet. Avoid brushing immediately after washing. Instead, gently press dry with a towel and allow to detangle naturally before brushing.
