first time user, its a quality product and would recommend. Read more
I love this shampoo! Its free of the harmful additives that shampoos can have. It smells of mint and makes my hair clean and shiny without stripping it of all its oils. Its also very gentle on the scalp. I tried the bar shampoos and they don't leave my hair as nice as SHE. I have continued to purchase SHE for my hair for a year now. I highly recommend it. Read more
My wife and I used the product for six months. We started with good results, but our scalp started to itch a lot, and it caused excessive dandruff. We stopped using it, but it was too late. After a long time, we still had dandruff and dryness, which was very damaging. I don't recommend it. Read more
I've been using this product for one full year this month and I wish I had a little more praise for it. I've been using the shampoo in conjunction with some DHT blocker/supplements and I can't say I'm blown away. Now, what I can say is that if I stop taking the pills and don't use the shampoo for a few days, I notice considerable hair-fall in the shower, so some combination of the supplements and the shampoo is working on some level. What I haven't noticed is any regrowth or thickening of the hair with the exception of body hair (gee, thanks). So, mixed results. I really like the smell ans how foamy it lathers up--Has a real premium feel to it. Read more
The shampoo/conditioner leaves my hair feeling fuller and healthier. I highly recommend it. Additionally, I communicated with the CEO of the company personally, and he was very honest and meticulous in answering my many questions. Read more
I’ve used these type of shampoos before and they have stripped my hair but this product is gentle, smells good and lathers really well. I have a sensitive scalp so the fact it contains no parabens or sulphates and is made in the US means I have confidence my scalp won't be irritated. I did as they suggested and left it on for a couple of minutes and my hair looked and felt great - more volume and thicker. This is now part of my daily routine. Read more
