Similar to the other OGX shampoos, I chose this product because it doesn't have sulfates which are supposed to be bad for your hair. I don't think this product made my hair "thick & full" as advertised, and it doesn't lather very much. I am disappointed in it and wouldn't purchase again.

This product for hair is amazing. It left my hair feeling strong and full. It is easy to wash with and smells very nice. I use it very frequently and goes along great with the conditioner. Other hair products most of the time leave my hair greasy this does the opposite.

[product:ogx-biotin-collagen-shampoo] is absolutely fantastic!! It takes my fine, limp, lifeless hair and turns it into thick, luscious looking hair. The volume achieved is insane; I look like I have twice the hair! Have never been so satisfied with a shampoo. Will be hard for any other brand to beat it! If you have fine, thin hair then [product:ogx-biotin-collagen-shampoo] is for you!!

I have only been using this product two weeks now and I have noticed a significant improvement with not only the overall volume of my hair but most importantly the overall health. Previously my ends looked very dry and damaged and now they look healthy! I will definitely keep using this shampoo and conditioner. I kind of regret not trying it sooner.

I've been using this shampoo for a few months now, it's my personal favorite. The consistency of the shampoo is interesting, it's not like a lot of other shampoos. My scalp feels so fresh and clean after using this, and my hair stays looking full and voluminous a lot longer. I dye my hair pretty frequently and it's really taken quite a lot of my hair, but this shampoo helps bring it back to its original glory.

First off, this OGX shampoo smells amazing! I have an oily scalp but lately it's been dry and this has been working for me either way because it really helps balance your hair. This particular shampoo softens and smoothes my hair but I also see it appearing more thick over time! My hair is also breaking less. I use it with their OGX Argan Oil Of Morocco Penetrating Oil and Organix: Renewing Moroccan Argan Oil, Weightless Healing Dry Oil, 4 oz (Pack of 2)

This shampoo has help with my hair fall out, due to my thyroid condition. It has given my hair more volume. However, it leaves my hair a bit brittle. I use ogx oils to aid with this issue. I like the smell that it gives my hair. All in all, I would purchase this again.

This shampoo makes me happy! I have very thick hair, which tends to be dry. When I tried it I immediately noticed that it made my hair so soft! I don't recall my hair ever being this soft. Also my hair doesn't break off so easily. I am quite satisfied with this product.

I actually love the shampoo, I just wished it got a little more lather than it does. Has a very nice smell as well. Lasts for 2 days with a beautiful smell. One of the nicest smelling shampoos I've tried. I'm actually excited to try the other ogx products! Deff worth the money! Great product!

First of all.... THE SMELL IS AMAZING! Its strong but I love it. This shampoo makes my hair feel clean and it stays cleaner before washing. My hair feels and looks healthy. I've been using this for 2 months and I have noticed a great difference. I will continue to try hair products from this brand!
