[This review was collected as part of a promotion.] I've been using the OGX Biotin & Collagen Shampoo lately, and it's been a great addition. Formulated with key ingredients—biotin and collagen, this shampoo is designed to help strengthen and volumize hair. The biotin helps with hair growth and strength, while the collagen adds a boost of volume. Besides, the shampoo gives a rich lather, and the scent is pleasant without being overpowering. My hair feels stronger and healthier after every wash. Overall, the OGX Biotin & Collagen Shampoo has made a noticeable difference in my hair's appearance and texture, and I’m really happy with the results.

Smells great and leaves my hair feeling great. Best for thin hair, don’t use on an oily scalp. I wish it would have noticeably improved my hair. Smells better than most shampoos. Satisfied with this but I feel like it’s missing something. I do recommend.

Really nice shampoo. I use quite a bit of the OGX line of shampoos and conditioners, and I still have this one however I will say it’s not my top pick. I think it would work really well with a different hair type but for me personally it left my hair feeling pretty soft but really frizzy. Still a good shampoo though and I would still recommend if you don’t have extremely curly, moisture hungry hair.

When I was in middle school and high school my hair always stayed the same length. But I realized I was using very cheap shampoo and not really taking care of my split ends or anything. I switched to this shampoo and my hair has grown about six inches!

The absolute best conditioner for thinning hair. OGX Biotin and Collagen Conditioner should be really expensive but it’s not! I actually have beautiful body and gorgeous shine every time I use this. It won’t weigh your hair down! Great for color treated hair because it’s sulfate free!

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!

It’s nice, great scent and biotin is pretty high up on the ingredients list which is awesome to see!!! However I stopped use because I’m removing products w silicones from my hair care routine :/. This has dimethicone I believeeee, so I stopped using it solely for that reason

When I bought this product I did not think it would work, after using the shampoo and condition I was very happy of the result. I noticed the first time I use this product. I am going to keep using this product and see how my hair look in three month.

I love this product,I am African woman with very kinky(coarse) hair. The first I tried this product my hair was dry and was breaking. Now it's feels healthy, it looks healthy and it is healthy. It has gone back its natural colour too. I can't touch stop touching my hair! Thanks

OGX Thick & Full + Biotin & Collagen Shampoo - 13 fl oz I have extremely fine hair and on top of that it was falling out at the follicle. Since I started using this OGX shampoo and conditioner about a yr ago I notice it has helped with my hairloss and makes my hair fuller. I now longer have excessive hair loss. I will continue to buy and recommend this product it as it has helped strengthen my hair follicle.
