How it works
Watermans gives backChemotherapy wards have had free Grow Me® from us since we started, and the nurses there recommend it. Good karma matters to us.
How we give
Real improvements in both my own hair and my clients, from stronger strands to healthier scalp condition with consistent use.
Sarah Sullivan · Certified Trichologist, UK Trichology Clinic, Sheffield
Quality dedicated hair growth treatments such as the Watermans Grow Me range is an excellent starting point to consider. Diligent use for 3 to 4 months can see a reduction in hair thinning and the hope of healthier hair growth.

Caffeine-only shampoos do not work. Grow Me® works as a team, in every wash:
Never with sulphates, parabens or palm oil. The shampoo is vegan. Cruelty-free. Made in the UK.
Grow Me® Shampoo: massage into a wet scalp and leave it on for 3 to 4 minutes so the formula can work on the follicles, then rinse. Four washes a week is what the study used.
Condition Me®: on the lengths and ends after every wash, rinse.
Grow More® Elixir: a few drops massaged into the scalp, no rinsing. One bottle of each lasts about 30 days.
Free UK shipping on orders over £45, so the Boost Set always ships free. Dispatched from the UK.
Subscriptions renew every 30 days. Pause, skip, change the date or cancel from your account in two clicks. No phone calls, no emails to chase.
Use as directed and if you are not happy, we will refund you. How it works
Month 1: Cleaner scalp, softer hair. Grow Me® on the scalp for 3 to 4 minutes, four to five washes a week. Condition Me® on the lengths. Hair detangles more easily and the scalp feels refreshed.
Month 2: Less breakage. Fewer snapped strands on your brush and pillow as lupine protein and biotin reinforce the fibre. Lengths feel stronger and look shinier.
Month 3: Fuller-looking hair. Less of your hair is breaking, so it looks and feels fuller. In our study, 83% said their hair looked fuller at this point. Keep going to keep the result.

50 days inCustomer's own photo“After 50 days I am very pleased. My hair might not feel thicker in a ponytail but it looks thicker and you can't see my scalp through my hair any more. I have ordered my second bottle to carry on for the recommended 3 months.”
7 weeks inCustomer's own photo“I've been using this shampoo and conditioner for about 6 to 7 weeks due to my hair randomly thinning. The improvement I've seen already is amazing. My confidence with my hair is much better and I've since purchased the set again and the hair mask.”
7 months inCustomer's own photo“I've been using this shampoo and conditioner for 6 to 7 months now and the difference in my hair is amazing. The condition of my coloured blonde hair is amazing, no breakage, super soft. I love it that much I bought the salon size in both.”
Long-term userCustomer's own photo“Rapid weight loss after surgery caused dramatic hair loss. I truly thought I was going to go bald. Then I discovered Watermans and won't use any other shampoo and conditioner. My hair is in beautiful condition, it's thicker than ever and I couldn't be happier.”
First weekCustomer's own photo“I haven't been using this product for a week yet and I'm already seeing improvement. My hair is fuller, it's glossy. I also have scalp psoriasis and it hasn't bothered me at all since I've been using this product.”
2 years inCustomer's own photo“I have been using Watermans for over 2 years and the proof is in my photos. I was a tape hair extension person for years so my hair was damaged and short with ratty ends. Now everyone asks me what I use.”
Repeat buyerCustomer's own photo“I had very thin hair before this shampoo. My hair is so healthy and thick now. I don't want to use any other shampoo but Grow Me.”
Most hair loss shampoos are a caffeine shampoo with a nice label. A supermarket shampoo is detergent and perfume. Grow Me® puts seven actives on your scalp for 3 to 4 minutes, every wash, and was tested on 122 people for three months.

Real improvements in both my own hair and my clients, from stronger strands to healthier scalp condition with consistent use.
Trichologists see hair loss every day, and the ones who recommend Watermans do it for a simple reason: a sulphate-free wash that puts seven actives on the scalp for 3 to 4 minutes, and clients who come back with hair that looks and feels fuller. Hair loss surgeons stock it for their patients too.
Caffeine-only shampoos do not work. If caffeine alone grew hair, every coffee company would sell shampoo. Grow Me® works as a team: caffeine wakes up the scalp and stimulates the follicles during the 3 to 4 minutes the shampoo sits on your head, and that is what lets the others get to work. Biotin, rosemary, niacinamide and lupine protein go in. Allantoin calms the scalp. Argan oil does its own job on the strand. Some of these have been used on hair for thousands of years. All seven, every wash.
For the formula to work, leave it on the scalp for 3 to 4 minutes before washing out.
Every Watermans formula is built on ingredients with their own test data, combined so they work on the scalp and the strand together.
Our actives are tested by the labs that make them. Our lupine protein was tested in the lab and on volunteers by our ingredient manufacturer. Caffeine, biotin, rosemary and niacinamide are among the most studied hair ingredients there are.
Our lupine protein is a trademarked active from our ingredient manufacturer: a hydrolysed lupine protein rich in peptides, trace elements and vitamins. It is in Grow Me® Shampoo and Grow More® Elixir.
Most shampoos lean on one hero ingredient. Grow Me® combines caffeine, biotin, rosemary, niacinamide, lupine protein, argan oil and allantoin, so the scalp and the strand are looked after in the same wash.
We have watched thousands of hair loss brands and products come and go, every one claiming to combat hair loss. Since 2012 Watermans has sold 6.5 million bottles, won a Queen's Award for Enterprise and run a three-month consumer study on 122 people. We are still standing. We must be doing something right.
Ingredient tests are carried out by the ingredient manufacturer. Our own three-month consumer study of Grow Me® covered 122 people.
Root causes
Most hair loss is one of these, and plenty of people have two at once. The medical side is for your GP. What you wash with is yours to control. Every card ends with the one thing you can do today.
Menopause, perimenopause, HRT changes, PCOS, thyroid problems and the contraceptive pill all change how long each hair spends growing, so the parting widens and the ponytail thins. Your GP can test for most of these. Wash with a routine that strengthens what you keep and does not strip the scalp. We go deeper on our hormonal hair loss page.
A shock, an operation, a high fever, Covid, a bereavement or a hard year pushes a crowd of hairs into their resting phase at once. They shed together two to three months later, and for most people it is temporary. Keep the routine gentle and consistent while it works through. More on our stress hair loss page.
Low iron is one of the most common causes of shedding in women, and crash diets, weight loss surgery and low protein starve hair of what it is made from. Hair is last in the queue when the body is short. Eat properly, and ask your GP for a ferritin check if you feel wiped out.
Heat, bleach, tight ponytails, rough towels and brushing wet hair snap strands halfway down. Broken hair has no white bulb on the end and looks exactly like thinning at the roots. This is the easiest one to fix: sulphate-free washing, a conditioner on the lengths, heat protection, and a weekly mask.
Pregnancy hormones hold on to extra hair for nine months, then let it all go at once around month three or four. It can look alarming on the pillow and in the plughole, and it is normal. Most mums see it settle by the first birthday. Our postpartum page has the full picture.
Pattern hair loss runs in families, in men and women. Each strand grows finer and the hairline, temples or crown thin first. No shampoo changes your genes, and we will not pretend otherwise. A GP or trichologist can confirm it, and a scalp that is not stripped every morning keeps the hair you have looking its fullest.
See your GP if hair comes out in round patches, falls out suddenly, your scalp is itchy, sore or scaly, or you feel unusually tired, cold or low alongside the shedding. Blood tests for iron, thyroid and vitamin D are quick and the common causes are treatable. A cosmetic routine works alongside that advice, never instead of it.

FAQs
Watermans products are cosmetics. They are not medicines and do not treat medical hair loss. If your hair is falling out suddenly, in patches, or you are worried, please see your GP or a trichologist first. Prices, stock and review counts on this page were checked in October 2026.
The best hair growth products are a sulphate-free shampoo and conditioner you can use every wash, backed by real customer results. Watermans Grow Me® Shampoo and Condition Me® Conditioner are made in the UK, rated 4.8 from 4,752 reviews as a set, and in an independent three-month study 83% of 122 people said their hair looked fuller.
Cosmetic hair growth products do not change genetics or hormones, and no shampoo can regrow hair that has stopped growing. What they do is keep the scalp clean and refreshed and stop fragile hair snapping, so more of the hair you have stays on your head and looks fuller. If hair is falling out suddenly or in patches, see your GP first.
The Grow Me® Boost Set: shampoo on the scalp for 3 to 4 minutes, Condition Me® on the lengths and Grow More® Elixir on the parting at night. Women make up most of our customers and 104 of the 122 people in our study, and most said their hair looked fuller after three months*. Going through menopause or just had a baby? We have a routine built for each.
Men usually want the hairline and crown dealt with, so the Shampoo and Elixir Set is the men's best seller: Grow Me® four or five washes a week, Grow More® Elixir on the temples and crown at night. All cosmetic, no drugs, nothing to prescribe.
Start with the Grow Me® Shampoo & Conditioner Set. Two steps cover the scalp and the lengths, it is our best-selling routine, and it costs £22.91 a month on subscription. Add the Grow More® scalp elixir or GrowPro® gummies once the basics are in place.
Expect cleaner, softer hair from the first wash, less breakage by around six weeks and fuller-looking hair by eight to twelve weeks of washing four to five times a week. That is why the 90 Day Money Back Guarantee covers a full 90 days of use. Results vary from person to person.
Yes. Grow Me® is sulphate-free, so it does not strip colour the way a supermarket shampoo does, and most of our customers have coloured hair. Bleached hair is more porous and drier, so follow every wash with Condition Me® and add Masque Me® once a week.
Yes. Wash as normal and keep conditioner off the bonds or tapes. Grow Me® works on your own scalp and hair underneath, which is where the shedding and thinning happen. It will not loosen bonds.
Grow Me® is a cosmetic shampoo with no drugs in it, and many customers use it through pregnancy and postpartum shedding. If you have any concern, check the ingredients list with your midwife or GP first. For hair that sheds after birth, see our postpartum hair loss page.
Many customers do, and Watermans supplies free hair care to chemo wards. Grow Me® is gentle, sulphate-free and drug-free. During treatment, ask your oncology team first, as some units prefer very mild products while the scalp is sensitive. After treatment, when hair is returning, it is a kind wash to start with.
Yes. Grow Me® is a cosmetic and does not contain or interact with either medicine. Keep taking what your doctor has prescribed. Many customers use Grow Me® as their everyday shampoo alongside a prescribed treatment, and apply the elixir at a different time of day to any topical treatment.
Grow Me® is made for adults with thinning or shedding hair and most children do not need it. For kids we make a separate, gentle range. If a child has sudden hair loss, see your GP rather than treating it with a shampoo.
Usually yes. There are no sulphates, and allantoin is in the formula to calm a scalp that feels red, itchy or tight. If you have a diagnosed scalp condition such as psoriasis or eczema, use it as normal and keep any prescribed treatment going. Stop and see your GP if a product ever makes a scalp condition worse.
Both. Every product here is unisex and suitable for colour-treated, curly and Afro hair. The formulas are sulphate-free, paraben-free and made in Britain, and every formula except Condition Me® is vegan.
This page lists every Watermans hair growth product. If shedding is your main concern, our best shampoo for hair loss page explains the causes, the routine and what to expect in the first 90 days.
Yes. Use the shampoo, conditioner, mask, hair oil or heat spray as directed for the full 90 days and, if you are not happy, the Watermans 90 Day Money Back Guarantee refunds you. Subscriptions can be paused, skipped or cancelled from your account in two clicks.
Yes. This is the part most people get wrong. Grow Me® is not a wash-and-go shampoo. Massage it into the scalp, leave it for 3 to 4 minutes so the caffeine and rosemary have contact time, then rinse. Four to five washes a week. Use it like a normal shampoo and you will get a normal shampoo's results.
The results come from using them. Grow Me® and Condition Me® are cosmetic products that reduce breakage and keep the scalp in good condition while you use them. Stop, and over a few months your hair gradually goes back to how it was. That is why most customers treat the routine as something they keep, not a one-off fix.
Yes. Grow Me® is a cosmetic, not a medicine. There are no drugs in any Watermans product, so there is nothing to prescribe and no prescription to renew. Seven cosmetic actives do the work: caffeine, biotin, rosemary, niacinamide, lupine protein, argan oil and allantoin. If you are already using a treatment from your GP or a pharmacist, ask them before adding anything new to your routine.
Yes. PETA lists Watermans as cruelty-free: neither our ingredients nor our finished products are tested on animals, and our suppliers follow the same standard. We have never tested on animals, anywhere, and never will.
We don't just avoid animal testing, we actively fund the fight against it. Watermans is a featured PETA UK Business Friend and donates to PETA's work against animal cruelty. You can check us on PETA's cruelty-free list.
A kiss of life for hair
*Based on an independent consumer study of 122 people (104 women, 18 men) who used unbranded Grow Me® Shampoo four times a week for three months. Most users said their hair loss had noticeably slowed down, they noticed less shedding and less hair loss when brushing, their hair density had increased, their hair looked fuller and healthier, and it felt thicker and stronger. Consumer perception results. Individual results vary. Watermans products are cosmetics, not medicines, and do not treat medical hair loss. Full study report available on request.
