This hair product really does what it says. It leaves my hair looking thicker, fuller, and healthier. I love this company so much and I love how it’s sulfate free. It affordable too. I would definitely buy again. I have been using this almost for 2 years now and I love it

Hey! I would recommend because, it smells good and it makes my hair so soft!!! I think this product would have to be easier to get out of the bottle! it helps with greasy hair! I am for sure satisfied with it, I would recommend using both conditioner and shampoo!!

[This review was collected as part of a promotion.] After almost 2 weeks of trying this ogx biotin and collagen shampoo, I can honestly say this stuff works! My hair isn't super thin, but I do have a lot of hair, and after even just the first use, I instantly felt like my hair was thicker and had more volume. It has a very pleasant coconut smell to it and suds up very nicely after the first shampoo wash! I would give this two thumbs up!

Ooohhh I never get tired of this stuff! I'm always looking to find something good for my hair, and stuff is fantastic! It provides it with nutrients that keep it happy and healthy. With curly hair like mine, using shampoos and conditioners that aren't specifically for curly hair is always a risky game, but if you use the right products after washing, it truly doesn't make a difference (at least for me)!

I've been using this shampoo and conditioner for years. Have loved it until recently. For some reason the shampoo, after a week or so, turns to a hard gel in the container. The first time it happened I thought it was just a fluke but this 2nd container has done it also. I wash my hair every day so it's not like it sits for long periods of time.

I am not a fan of drugstore hair products, but if I ever have to OGX is the range for me. Thick &Full biotin range is my favorite. It truly makes my hair to appear more full and very soft and shiny. It smells amazing and little goes a long way. What else do I need in my shampoo.

Really good shampoo. I have very thin hair and it cleans my hair well while adding a bit of a volume boost. I love the smell and find it very easy to use, as it goes from a thick gel to a gentle lather and makes me enjoy washing my hair. And the smell lasts. Have repurchased and would definitely recommend.

Just like the conditioner I very much love OGX shampoo. I started using this brand after I started putting fashion colors in my hair and from my knowledge it helps to retain the color a little bit better than if you were to use regular drugstore brands

I have fine hair that is recovering from being over processed (highlights & dying it too blond). I’m usually sceptical of what hair products can really do, but I was pleasantly surprised after I used this! My hair is fuller and feels so healthy & shines! Great product!

I love how this made my hair look healthy and shiny, but my hair came out in clumps after first use. My scalp completely freaked out and had terrible eczema/dry/blisters for a week after. It still has not recovered. Do not buy, especially if you have thin hair.
