Grow Me® Shampoo Consumer Study Results
122 people washed with a blank bottle for three months. Here is what they said.
Grow Me® Shampoo was put in front of an independent research company and a panel of real users. The bottles were plain. No Watermans logo, no claims on the label, no marketing. Participants washed with it four times a week and reported what they saw and felt. These are their answers, exactly as recorded.

“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.”

“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. I've since purchased the set again and the hair mask.”

“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 bought the salon size in both.”

Was Grow Me independently tested?
Yes. The consumer study was carried out by Ayton Global Research, an independent research company. Watermans did not recruit the participants or collect the responses.

Three months. Participants used the shampoo as part of their normal routine for the full period before the final results were recorded.
How often did participants use Grow Me Shampoo?
Four times per week, every week, for three months.
Was the Watermans brand visible during the study?
No. Grow Me® was supplied in blank, unbranded packaging, so participants were reporting on their experience with the formula rather than reacting to the brand.
How many people took part in the study?
The substantiation document records 104 females and 18 males.
What percentage of users noticed less shedding?
75% agreed they noticed less shedding, and 79% agreed there was less hair loss when brushing.
What percentage said their hair looked fuller?
83% agreed their hair looked fuller, and 82% agreed their hair felt thicker.
Are these medical results?
No. This was a consumer study, not a medical trial. The figures are consumer perception results, which means they record what participants said they saw and felt. Grow Me® is a cosmetic shampoo. If you are worried about significant hair loss, speak to your GP or a trichologist.
