How it works
Watermans gives backChemotherapy wards have had free Grow Me® from us since 2014, 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.

AllantoinHair does not change in one month, and our 122-person study ran for three months. A litre is four 250ml bottles' worth, so the subscription sends a fresh one every 2 months at 15% off. Change it to every 3 months in the dropdown if you use less.

Work a small amount into wet hair and massage it into your scalp for 1 minute. Leave it on for 3 to 4 minutes so the actives have time to work, then rinse. Feel the tingle? That is our seven-ingredient formula getting to work. Most people feel the tingle for a few minutes. It is completely normal, and it is why you leave it on for 3 to 4 minutes.
Use it 4 to 5 times a week. In our study, 122 people used it four times a week for three months. Follow with Condition Me® on the lengths.
Avoid contact with eyes. If this happens, rinse straight away with clean water. Do not use if you are allergic to any ingredient. Keep out of reach of children.
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. Why sulphate-free matters.
Month 1: scalp feels deep-cleaned and refreshed. Hair feels softer and detangles more easily.
Month 2: fewer snapped strands on your brush and pillow. Lengths feel stronger and look shinier.
Month 3: hair looks fuller and feels thicker as less of it breaks. 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.
If it is working, why would you stop?

Four bottles' worth, delivered before you run out. Leave it on the scalp for 3 to 4 minutes, use it 4 to 5 times a week, and give it the full 90 days.
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.
What it does for your hair and scalp
Good shampoo
Helped thicken my hair, it’s fine and thin. Recommend it to all my friends who say their hair is going thin
There are no words to describe this. I had chemotherapy and lost every single strand of hair. I was recommended this on my cancer site and well I started by massaging it in my scalp and carried on doing this! The hair growth was amazing. I went on to recommend it to about 20 people whom all loved it. My friends whom hair had gone thin through over dying it also used it. So it’s way above 20 people with great results do not hesitate to buy it.
I consistently use this shampoo and elixir at night and find that my hair feels healthier and stronger. I have tried other products but they tend to be either too dry or too oily. WATERMANS has a great balanced product for my hair and scalp.
I used this shampoo years ago but after moving to Finland couldn’t get hold of it. Before Christmas I put an order in and delivery was quick and smooth. Having used this and the conditioner for a month now I can really feel the difference. I don’t use it for hair growth but for anti dandruff/flaking skin reasons. It has increased the volume in my hair undoubtedly but I have no dandruff. Having used the most popular anti dandruff shampoo before which contained sulphates, this has made my hair and facial skin feel healthier and less irritated.
This product makes my scalp feel very clean and my hair looks revitalised. No dryness or oily feeling between washes. Quality shampoo and conditioner that lasts for ages. Tried many different brands but always come back to this one.
I've been using Watermans Shampoo and Conditioner for a few years now; as a medical doctor I have recommended it to patients who have commented on my hair.
It really reduced hair-loss at 58, and is great for everyday use. An A+++ product.
I started using the grow me shampoo during menopause , after showering each day I was pulling handfuls of hair from the plug hole. I tried a few products but this one really work's. I still use it daily. Now my hair is thicker and the longest it's been in years.
I have been using the shampoo for years now. I love it!
I reviewed back in February after very little usage and was thrilled. However after more use, and more photos to show the difference I can honestly say I'm feeling more and more confident about my hair and other people are noticing it more now too.
I'm so glad I stumbled across this by accident it's now a daily talking point and I've pointed several people to the watermans direction for their hair loss/thinning. I really am so greatful especially as I can also pay via clearpya and pay in, installments meaning I can spend more on an order l. My most recent purchase were the salon size bottles and they're still going strong a month later, definitely worth the extra money.
In my photos the top left is when I started in January, the bottom right was this evening 18.07.24
I'm generally quite cynical about beauty claims, but this shampoo definitely made my hair grow longer more quickly. It's a bit early to tell whether the thickness is improved. Oh - and faster growing fingernails too!
One month ago I ordered my first Watermans grow me shampoo bottle set (x2). And I totally fell in love with it the first time I try it on my hair, the foamy sensation along with the minty smell leaves my hair feeling soft and even new tiny hair has starting to grow in my hairline where I used to have receding patches. Watermans has become my new favorite shampoo brand and of course my new favorite hero!! I'm never gonna change it for any other shampoo out there in the market, because W grow me is totally the best. Thank you so much for everything Watermans! Greetings
I have used this before when growing out my short hair during covid. It is now all one length in a bob. I have started using again as going a bit thinner at the front due to menopause. Brilliant product. Lots of new growth and my hair is thicker and in great condition. Thanks Watermans 😊
The best shampoo I'll never use anything else ❤️
I took the after photo about 65 days after I started using the shampoo, conditioner and elixir. I have to admit, I was pretty surprised when I compared it to the before photo. I really don't know what else I need to say. I think the photos speak volumes.
So goood and I l love it
Just want to say that these products are life savers ,no other products in market can stop your hair loss fully ,this shampoo and conditioner set can bring back your lost hair as well ,no match to the quality of these products
So try it as mentioned and you will never be disappointed that's for sure .
God bless them
P.s the results of before and after pictures in my case in just 3 months gap
I have been using this shampoo for a few months now. My hair is much improved, I don’t have any thinning areas anymore. Before I started using this I was getting a lot of hair falling out. The biggest difference I can see is atriums the sides by my ears, I was more or less bald…not anymore thankfully.
Give it a try, don’t think you will be disappointed
I use the bundle every night! A little goes a long way.
I started my hair growth journey back in May and my results speak for themselves.
I still have a long way to go but not constantly worried about bold patches when doing up my hair now. This in conjunction with a hair supplement I take has given me so much more confidence.
10/10
As my hair is thinning due to a genetic disorder it has not grown despite my using Waterman's for around one year. My hair is fine and fly-away. However, it feels thicker and is shinier with much more body. I often get comments about how healthy my hair is. So, I will make sure that I always continue to use Waterman's growth shampoo. It's the absolute best shampoo I've ever used.
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.

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 and review counts on this page were checked in November 2026.
Yes. It is exactly the same Grow Me® formula, with caffeine, biotin, rosemary, niacinamide, lupine protein, argan oil and allantoin. The litre is simply four 250ml bottles' worth, made for families, salons and anyone who does not want to reorder every month.
For one person using it 4 to 5 times a week, about four months. For two people, about two months, which is why the subscription defaults to every 2 months. You can change it to every 3 months.
Massage it into a wet scalp and leave it for 3 to 4 minutes so the actives have contact time, then rinse. Follow with Condition Me® on the lengths. Use it four to five times a week. In our study, 122 people used it four times a week for three months.
Yes. Grow Me® is sulphate-free and suits men and women of all hair types, including colour-treated, curly and Afro hair. Keep it out of the reach of children.
Hair grows on a slow cycle, so one bottle is enough to feel a cleaner scalp and softer hair, but not enough to judge fullness. One 250ml bottle used as directed lasts about a month. Our independent consumer study ran for three months, and the Watermans 90 Day Money Back Guarantee needs three bottles' use, which is why the plan delivers monthly.
Yes. Grow Me® suits men and women of all hair types, including colour-treated, curly and Afro hair. It is sulphate-free and paraben-free, and it is made in the UK.
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.
No shampoo can stop medical or genetic hair loss, and any brand that claims otherwise is overselling. A good shampoo reduces breakage and keeps the scalp in good condition, which helps the hair you have look fuller. If hair is falling out suddenly or in patches, see your GP first.
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.
Yes, at any time, from your online account, with a clear cancel button. No calls, no emails, no fees. You can also pause, skip a delivery or change how often it comes. Cancelling takes effect before the next scheduled payment.
Yes. Use as directed and if you are not happy, we will refund you. How it works. Subscriptions can be paused, skipped or cancelled from your account in two clicks.
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.
See your GP if hair falls out suddenly, in round patches, with an itchy or sore scalp, or if you are worried. Blood tests can check iron, thyroid and vitamin levels. A cosmetic shampoo works alongside medical advice, never instead of it.
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.
