The BEST

"After losing a lot of my hair on accutane, I started using this shampoo. It makes my hair feel so nice and has helped me regrow my hair to be thicker. I recently tried a different brand after using this for a while and it just didn’t compare, I immediately had to buy this again and get back to it. It smells amazing, has a great lather, and has made my hair so healthy"

— Emily M. (5/5)

Can’t use any other shampoo now

Great Product, Bad Packaging

"Product itself is great, I've been using it for years. However the packaging kind of sucks. The pump is not long enough to fit your hand under it."

— Sam G. (3/5)

Hard to Pump

"Love this product. Hate the bottle. The pump is not long enough to fit your hand under it."

— Sam G. (2/5)

Great!

"I used to have super thick hair and four kids later, it's now very fine. This shampoo is the first to help it feel fuller and stronger, while being smooth and shiny. The smell at first was alot but it's grown on me and I like knowing my hair smells good for a long time! I typically wash once every 2-3 days and this keeps my hair clean and shiny for longer than any others I've tried!"

— Abby K. (5/5)

The best shampoo ever !

"I will repurchase this every single time!! The only shampoo that keeps my hair clean and feeling amazing! I reccomend to all my friends. As a pro athlete, it gets my gross training/game hair clean as well - which is hard to do without stripping too much away!!"

— Shea H. (5/5)

Wouldn’t buy again

"Smells amazing - but I’m noticing a ton of shedding/breakage and my hair has been feeling really dry since I started using it, even with the leave-in and oil."

— Kristen B. (2/5)

Wonderful

"I hvave been using this for several years now and my hair feels wonderful. I get asked often how my hair is soft and shiny."

— Ann C. (5/5)

I love how it makes

"I love how it makes my hair feel clean. Sometimes I think I need the fine hair shampoo. I am kind of in between."

— Yaeli E. (4/5)

Love it

"I have been using this conditioner for a while now and I absolutely love it makes my hair so soft and beautiful the others on really nicely."

— Olga O. (5/5)
