My Fave!!
About 9 months ago I was sent this shampoo, conditioner and leave in treatment to review by a third party company. I have to admit, the first thing I noticed was the scent. It's marvelous!! The second thing I noticed is that after a couple of uses, my hair didn't break near as much. There wasn't a l...

Scent is wonderful, overall product not as much
I received this product to try for free in exchange for sharing my opinion about it. I have fine hair that lacks volume, as well as certain pieces that don't really seem to be growing at all, so I was very excited to try this product. The first thing that I noticed about it was the scent. Wow! This ...

I wanted to like it
I have fine waves/curls that are usually shoulder length. I got my hair fairly long and managed to grow out most of my breakage this year, and I was really excited to find a shampoo that would maintain my new mane. I chose this one, and unfortunately that turned out to be a mistake. The thickness i had achieved for the past year quickly disappeared after just a couple of washes. I was drying my hair when i realized i had a TON of breakage around the top of my head, and the rest of my hair looked like straw. My hair is super thin again, and badly damaged. I will be switching back to my old shampoo.
Growth
My hair has grown so much since I've been using this product and my hair has never been this healthier before
Constant repurchase
Hair Type Wavy Hair
This is my favorite shampoo to double cleanse with. I feel like it gets my hair feeling super clean and helps with my breakage. I have not notice any protein overload and I've been using it for about 3 years now.
Horrible .
Ive lost so much hair and progress due to this product . When I first started using this I noticed strands of hair coming out after I showered and I kind of just ignored it but the times I wouldn't use this product it wouldn't happen my hair only came out after showering when using this product . I used it for abt 3 months and noticed my hair getting thinner and thinner but never thought to blame this product until I see other reviews . Made my hair thinner , more dry , etc . Definitely growing faster from the root but at what cost ..?
Wanted to love it
I really had high hopes for this shampoo, but unfortunately, that wasn't the case. It smells really good and I like how it lathers but the downfall is it makes my hair fall out, flat and now I have a couple bald spots on the top and sides of my head. I'm so stressed out right now.. I can't even return it because it's been more than 30 days. I'm gonna have to throw away 2 bottles now.. such a waste of my money. 😞💔
