What happens on the outside is a reflection of what goes on on the inside. If your hair has been feeling more lank, thinner, or harder to manage, the answer is more likely to be in your diet than in a new shampoo.

More InformationWhat Tim Spector actually said
Professor Tim Spector, founder of the Zoe nutrition programme and one of the UK’s leading voices on gut health, has talked extensively about the benefits of black coffee for the microbiome. His recommendation of three cups of black coffee a day is not about the caffeine. It is about the polyphenols in coffee that feed the beneficial bacteria in your gut.
A healthy microbiome means better nutrient absorption. And better nutrient absorption means the vitamins and minerals your hair follicles need are actually getting to where they need to go.
So does coffee actually help hair growth?
Indirectly, yes. The connection runs through your gut. If your gut health is in good shape and your body is absorbing nutrients properly, your hair benefits. Coffee, specifically black coffee without sugar or milk, contributes to that gut environment.
There is also separate research on topical caffeine and hair follicle stimulation, but that is a different conversation. For most people the simplest starting point is just drinking good quality black coffee regularly and paying attention to the broader diet picture.
What should you actually do?
If your hair has been feeling different lately, the question worth asking is not what shampoo to switch to. It is what has changed in your life in the last three to six months. Stress levels, diet, sleep, hormones. Hair growth cycles run on a delay of around three months, so what you are seeing now reflects what was happening then.
- Three cups of good quality black coffee a day if you tolerate caffeine well.
- Oily fish two to three times a week for omega-3 fatty acids that support scalp health.
- Reduce ultra processed food, which disrupts the gut environment that supports nutrient absorption.
- Get your iron and ferritin levels checked if you have noticed increased shedding. Low ferritin is one of the most common and most overlooked causes of hair loss in women.

Take the Free Hair ScoreWhen to come in
If your hair has been changing and you are not sure why, the most useful thing you can do is have it properly assessed. At NOCO we use the Kerastase K-Scan to get a clear clinical picture of your scalp and hair condition before we recommend anything. It takes the guesswork out of it.
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.
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.
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.
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.
Whether you trusted your hair to the wrong stylist or an attempt at home colouring went sideways, a dye mishap can feel like a nightmare. But no hair colour disaster is completely unfixable in the right hands. The first step is understanding what actually went wrong.
Colouring hair is a more delicate process than the box dye adverts suggest, particularly when bleach is involved. Here is what we see most often and what can be done about each one.
Brassiness and bad blonde
Blonde is one of the most popular colour results and one of the easiest to get wrong. Too much lift in one direction can leave you with green-grey ashy tones, orange brassiness or a yellow that reads more Barbie than beachy.

Hot roots
Hot roots appear when the hair at the root develops differently from the rest, creating a two-tone effect that looks unintentional. It happens most often when previously processed hair reacts differently to fresh colour, or when the heat from the scalp causes the dye at the root to develop faster and lift higher than the lengths.
A small amount of anti-brass or cool toner applied to the roots can help at home. In a salon, a colourist can correct hot roots using a slightly deeper shade at the root to balance the overall result. For future colour, applying the dye to roots last, after coating the lengths, reduces the risk of this happening again.
Colour that has gone too dark or intense
Left colour on too long? The first response is to wash immediately, several times if needed. A clarifying shampoo strips colour faster than a regular shampoo. Follow immediately with a deep conditioning treatment as clarifying shampoo is harsh on the hair structure.
From there, a stylist can advise the best route. In some cases the dye can be removed or lifted. In others, encouraging it to fade naturally over a few weeks while protecting the hair is the better option. Highlights or balayage can also be used to break up the intensity and lighten the overall effect without a full removal process.
Patchy or uneven coverage
Patchy colour coverage is one of the most common results of home dye jobs and can also happen with inexperienced stylists. The causes range from incorrectly mixed product to uneven application, damaged hair that absorbs colour inconsistently, or missed sections.
A professional can identify exactly what caused the patchiness and correct it using a combination of targeted re-colouring, toner, gloss treatments or condition work depending on the root cause. Colour often needs more than one pass to build depth evenly, in the same way that painting a wall benefits from an undercoat before the finish coat.
Stripey or chunky highlights
Bold, visible streaks rather than blended highlights usually happen when sections placed in foil are too thick. The result lacks the dimension and movement that makes highlights look natural.
Balayage used to soften and blend overly chunky highlight work at NOCO Hair Bristol.
The two most effective salon fixes are blending the base colour back through to reduce the contrast between highlighted and unhighlighted sections, or using balayage to hand-paint colour in a way that disguises the foil sections and creates a more gradual, natural result.
Hair dye on skin
Staining around the hairline, neck and ears is extremely common. At the salon we use a professional stain remover. At home, milk on cotton wool works surprisingly well. Regular soap and water clears most fresh stains. For anything more stubborn, baby oil, a gentle body scrub or a small amount of rubbing alcohol applied lightly without scrubbing will usually clear it.
Prevention is more effective than removal. Always use gloves when colouring at home, wipe any drips immediately before they set, and apply a barrier of moisturiser or Vaseline around the hairline before you start.
Damaged hair after colouring
Bleach and permanent dyes work by lifting the outer protective layer of the hair shaft. This is necessary for the colour to penetrate, but it leaves the hair more vulnerable to breakage, frizz, dryness and heat damage until that outer layer recovers.
Every visit to NOCO includes a scalp massage as standard. We do it because it feels good, yes. But the reasons go deeper than that. Head massages have a genuine and well-documented effect on physical and mental wellbeing that most people do not fully appreciate.
The history of head massage runs through European cave paintings, ancient Chinese texts and traditional Indian medicine. People have always understood intuitively that this kind of touch does something. Modern science has spent the last few decades catching up and confirming why.
What a head massage actually does
The nervous system piece
Your nervous system has two branches. The sympathetic, which triggers the fight or flight response, and the parasympathetic, which controls rest and recovery. These two are designed to balance each other. The problem is they were built to handle short, resolvable threats, not the kind of low-level ongoing stress that most people carry every day.
When stress remains unresolved, the sympathetic system stays activated longer than it should. Stress hormones continue to circulate. This is linked to high blood pressure, reduced cognitive function and a range of other problems over time.
Massage is one of the most effective ways to manually switch this off. The touch activates the parasympathetic response and encourages the body to release the hormones it needs to recover.

Can you do it at home?
Yes, and it is worth doing. A simple self-massage using your fingertips in slow circular motions across the scalp for a few minutes a day can make a noticeable difference to scalp health over time. Some people use a few drops of oil to help with glide. Others use a silicone scalp brush or an electric massager.
The professional version will always go deeper because a trained pair of hands can feel tension and respond to it in real time. But a consistent home routine between visits compounds the benefits significantly.
Does diet affect hair growth? Yes, it does. Hair condition is one of the first places your body shows a nutritional gap. Not dramatically, not overnight, but over time the quality, density and growth rate of your hair reflects what you are putting into your body.
We talk about this in the salon regularly. Someone comes in frustrated that their hair feels thinner, grows more slowly, or keeps breaking. They have tried products, changed their routine, and nothing seems to stick. Often the answer is not on the shelf. It is on the plate.
Why food matters for hair growth
Hair is not essential tissue. The body does not prioritise it the way it prioritises your heart or your organs. When your nutrition is depleted or unbalanced, hair is one of the first things to suffer because the body redirects resources to what matters most for survival.
This is why crash diets, restrictive eating and sudden changes in nutritional habits can trigger noticeable hair shedding within a few months. The hair you lose today often reflects what was happening in your body two to four months ago.
The nutrients that matter most
You do not need a complicated supplement regime. Most people simply need more of what is already available in a balanced diet. These are the nutrients we talk about most in the salon.
What tends to cause problems
Deficiency is one side of it. But we also see clients whose hair suffers because of what they are doing to their diet rather than what they are missing from it.
Yo-yo dieting puts the body under significant stress and hair is often the visible consequence. Cutting out entire food groups, particularly protein or fat, removes the building blocks the hair follicle needs. Juicing phases that replace full meals can look healthy on the outside while quietly depleting the nutrients your scalp depends on.
The body is not designed to process dramatic nutritional swings. Hair, being non-essential tissue, reflects those swings quite clearly.
What you can do
Start with the basics before reaching for supplements. A varied diet with enough protein, plenty of vegetables and adequate healthy fats covers most of what your hair needs. Specific deficiencies are worth investigating properly through a GP or nutritionist rather than guessing.
If your hair has been noticeably thinner, shedding more or growing more slowly over the past few months, a blood test checking iron, ferritin, vitamin D and thyroid function is a sensible starting point. These are the markers we most commonly see linked to hair changes in the salon.
And remember, the hair you are seeing today is a reflection of what was happening two to four months ago. If you have recently improved your diet, the results will come. They just take a little time to show up.
When diet is only part of the picture
Nutrition is one piece of it. But hair condition is also influenced by stress, hormonal changes, the products you use, heat styling, and the physical condition of your scalp. A proper consultation looks at all of these together rather than treating them as separate problems.
If your hair has been concerning you and a dietary change has not made a difference, it is worth coming in for a proper assessment. We can identify whether the issue is nutritional, structural, scalp related or a combination, and give you a clear plan from there.
