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!!

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.

Worth it!! All hair types 
I am on a hair care journey. I want to grow 3 inches of hair by December and it is now in the middle of August. I have foresee hair, low porosity, and about bra strap hair length in the back and a little past shoulder in the front. My hair is extremely damaged. I have always used their mega soft curls and thought that penetrated my hair well. I went ahead and bought their acidic bonding curls, shampoo and extreme length shampoo and conditioner. I put both in my hair last night, blow dry my hair with a little heat protected and very light oil . Honestly, I can tell that the extreme length has something in it because my hair feels extremely more sturdy, almost as if it's thicker. Like it was coded with something, but my hair is soft and flowing. I decided to trim my ends and I will report back with how much hair growth I have but definitely I can see how this makes your hair stronger from breaking because I physically feel stronger and I've never had a product do that before.
Smells amazing and works!
