Smells amazing and leaves my hair feeling thick and fluffy once it dies. I've combined this with the conditioner and I've seen a major change in my hair. It feels more healthier and even looks shinier

Im not a shampoo expert and I have pretty bad hair due to health conditions and bleaching. but if it actually has biotin and collagen in it than its great! the smell isn't the best either but thats personal preference.

My second favorite shampoo. My hair easily breaks and it's always frizzy. I usually don't blow dry my hair after a wash due to intense frizzy but using this shampoo makes it less frizzy when blow dry.

I've been buying this OGX, but I don't notice any difference in the thickness of my hair or the fullness. Overall it's a fine shampoo and conditioner, but I'm not in love with it.

Keeps hair bouncy and smelling good! Coupled with the conditioner, this is the best set that I have used in a long time. A very small amount is needed for a full head of long hair! [product:ogx-biotin-&-collagen-shampoo]

Leaves hair shiny and gives it volume. Helped with hair fall and dandruff. Great smell too. Could skip a day or two when it comes to washing my hair without having oily roots.

Love this and the shampoo. Leaves my hair feeling clean and voluminous not dry. Used a different shampoo for a few days and noticed immediately how much I missed this stuff

This is my all time favorite brand to use on my hair. My hair doesn't have as much fall out and is always lush. My hair tends to smell fresh for days afterwards. It's a little on the pricey side but you're getting your money worth.

I have been using this shampoo for 5 years now. It has never changed and still effectively cleaning & increases the volume my hair. Whenever I have to use another shampoo, I lose hair. This product keeps my hair very healthy.

I will never use another shampoo brand. This stuff is amazing!! I have thin hair and this product gives my hair so much volume. I love using the shampoo and conditioner combination. Great product!
