For years I used Bilolage Volumetherapie, full lift, but it's no longer made. I tried other volumizing shampoos, but was disappointed, each of them leavening my hair limp and flat...until I tried OGX Thick & Full. This is an awesome product and it's sulfate free. My has never felt or looked so good.

[This review was collected as part of a promotion.] I have already used this brand and I love the essence, it meets the objective, it is efficient, the texture it has, and also the price which is very affordable, it is worth trying it and what can I say about the very good ingredients, plus I like the packaging because it saves space.

[This review was collected as part of a promotion.] I love this shampoo. It smells awesome & leaves my hair feeling so soft & smooth. It’s also making it feel more full which is nice because it’s been thinning a lot since I had a medical procedure a couple years ago.

[This review was collected as part of a promotion.] Biotin and collagen shampoo is a great shampoo, packaged well soap texture no smell very effective. This shampoo worked so well with my hair not real expensive. Definitely recommend made my hair, thicker soft and shiny. 

I've been using this shampoo and conditioner combination for about a year now, and it's hard to switch to a different product because of how much it has helped my hair grow and how much thicker it feels now, absolutely wonderful results! I have tight, dark, 3c type curls, natural hair, and I identify as Black-Latina. I'm not sure if this was an effect of this shampoo/conditioner combo or where I live in the US, however, it hasn't helped much with the frizziness of my hair, but like I said, it could have to do with the fact that I live in Ohio, arid, windy, dry, or humid, no one knows most of the time. Overall, absolutely wonderful product and has done exactly what it says. Over the last year I've noticed how much healthier my hair looks and feels. Would 100% recommend for someone who's looking to regain some hair health, growth and body!

I'm never going not use this brand. After using the biotin shampoo and conditioner only once my hair smelt amazing and was super soft. My hair is also super thick, course, and wavy/curly and this helps the frizz go down a bit too which is a big plus.

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

So I bought this one by accident instead of the coconut milk one. And I’m so glad I did!! The way my hair feels and looks is fantastic! I get compliments every day! Y’all I live in Texas where there’s more humidity than anything and ever since I started using there problem big hair didn’t seem to be my biggest problem anymore. Do yourself the favor and buy it!

[This review was collected as part of a promotion.] this shampoo smells so good and my hair actually continues to smell like it afterwards which i love because it smells fresh and clean ! i do double cleanse and this has cleaned my hair very very good and is definitely supportive to its word ! would definitely repurchase !

I am a 64 year old female and have had "super" baby fine hair my entire life. I have tried many hair products throughout the years that claim to improve the look and texture of your hair but, this one is the ONLY one that has ever actually worked. After my very first shampoo, I noticed the difference, as did my husband. Very little of this product (a drop or two) is all that is needed for really great results. If you have baby fine hair, you should try this shampoo. You will not regret it!
