Ayton Global Research ran the study from blank, unbranded bottles, four washes a week. Consumer perception results, individual results vary. See every result.
One 250ml bottle used as directed lasts about a month. Hair grows on a slow cycle, so the first month gives you a cleaner scalp and softer hair, and months two and three are where fuller-looking hair shows. That is why our consumer study ran for three months, why the 90 Day Promise needs three bottles, and why most customers subscribe. Hair care is not a quick fix. It is a routine you keep, like brushing your teeth.

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.”

Root causes
Hair falls out after having a baby because pregnancy hormones keep extra hairs in the growing phase, and when oestrogen drops after birth those hairs shed together. The American Academy of Dermatology says shedding peaks about four months after giving birth and most women see normal fullness return by their child's first birthday.
Hormone drop
After birth, oestrogen falls sharply and hairs held in the growing phase move into shedding at once.
Sleep loss
Broken nights and exhaustion add physical stress, which adds to shedding.
Nutrition
Pregnancy and breastfeeding use up iron and nutrients, so hair gets less.
Stress
The emotional and physical strain of a newborn can prolong shedding.
Breakage
Quick ponytails, dry shampoo and skipped conditioner make fragile hair snap.
Thyroid
Postpartum thyroid changes are common and can cause thinning, so mention it to your GP.

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 shampoo for postpartum hair loss is gentle, sulphate-free and strengthening, so fragile hair snaps less while shedding settles. Grow Me® Shampoo is vegan, free from sulphates and parabens, and combines caffeine, biotin, rosemary and lupine protein. The set with Condition Me® is rated 4.8 from 4,752 reviews.
Postpartum shedding usually becomes noticeable a few months after birth and peaks about four months after, according to the American Academy of Dermatology. Most women see their hair return to normal fullness by their child's first birthday, and many sooner.
Grow Me® is a rinse-off cosmetic shampoo, so it is washed away and not swallowed. If you have any concerns about products while breastfeeding, ask your midwife, health visitor or GP. Always check with them before taking supplements.
Speak to your GP, midwife or health visitor before taking any supplement while pregnant or breastfeeding. GrowPro® gummies contain biotin and zinc, which contribute to the maintenance of normal hair, but your healthcare team knows your full picture.
Wash with a light, sulphate-free shampoo, condition only the lengths, blow-dry roots upwards and try a shorter layered cut. Avoid tight ponytails, which pull on shedding areas. InstaHair building fibres give instant coverage at the hairline.
See your GP if shedding carries on past your baby's first birthday, comes out in patches, or you feel very tired, cold or low. Iron deficiency and postpartum thyroid problems are common and treatable.
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 Promise refunds you. Subscriptions can be paused, skipped or cancelled from your account in two clicks.
