Rated 4 out of 5 by from I like it! It’s really good if you have thick course hair! I feel like if your hair was in the finer side it might be too heavy. It feels so smooth even a week later!

Rated 3 out of 5 by from Ok shampoo So it actually chills the frizz and adds gloss without killing your curls, it seems it cuts blow-dry time in half, but you gotta pair it with the weekly mask and hit it with heat or it's just an okay gentle shampoo, but it kind of has irritated my scalp.

Rated 4 out of 5 by from Great thick rich lather I like the thickness and rich lather this shampoo has. Makes my hair really smooth and shiny has a bit of a strong scent. I have used it with the whole system and it does keep my hair frizz free.

Rated 4 out of 5 by from Nice shampoo I really like the texture and results of this shampoo. Four stars for the overpowering strong scent. It’s way too much for me and it stays throughout the day.

Rated 5 out of 5 by from Good with overall smoothing system I love that is comes with a pump. It’s like a mini keratin Brazilian treatment if you use this whole system like it’s designed. It’s a lot of steps but a really good price.

Rated 5 out of 5 by from Pleasant surprise I've been using this system for a few weeks now and I can honestly say my hair feels sleeker and more manageable. I live in a high humidity area and I can tell a difference in the smoothness of my hair after being outside. I also love the scent of these products!
