Works wonders!

I have dry overprocessed hair because of bleaching, and am in my 50s. Not many products do what they say, but after using this shampoo, my hair is always silky soft. I love it! My hair is also curly so frizz is always an issue... But not with this shampoo. So if you have the same problems I do, then I encourage you to try it. You won't be disappointed!

This shampoo works!

This shampoo lathers up really nice and left my hair feeling clean and soft! The packaging is effective and easy to use. Sometimes I find the pumps on certain shampoos annoying but this one is nice. I noticed my hair with more of a shine after using only once!

Returned product

Returned it because there is a law suit claiming it makes your hair fall out. No thank you.

Smells greata

Some recommend this shampoo because I was loosing too much hair. I just started using it hopefully it works. It smells great and I love how my hair feels.

The Formula Has Changed

I had previously bought a bottle of this same shampoo from Sam's club and it worked great! I recently restocked this month and it is not the same, my hair now get oily within one day of shampooing!

Good shampoo; strongly scented

The shampoo does its job of making my hair feel clean and manageable, but it’s too strongly scented for me. I don’t have allergies to perfumes, but would recommend that anyone who does should be cautious about trying this.
