I bought this about 2 months ago and it does do what it says, my hair has grown significantly since using this product and it makes my hair appear thicker, the only problem I have with this product is the smell. I'm switching to a different one with the same brand to try to get the same effect just with a better scent. I love OGX!

[This review was collected as part of a promotion.] What I truly liked about the OGX Biotin & Collagen Shampoo For my hair is that It was easy for me to use. I also liked how you only have to put out a couple of pumps that will last you for a couple of months because of the product & applicator. I didn’t dislike anything about the OGX Biotin & Collagen Shampoo. Where I used it was when I had to go to a couple of family events. I just wanted to see how long my OGX Biotin & Collagen Shampoo would last me weekly & every day. Yes, I would recommend this product to others, I would also go into detail as to why I really recommend this product. Something that I would have wanted to know before I got to try out the OGX Biotin & Collagen Shampoo is if the product lasts longer than 2 months. I received this product for free complimentary testing purposes from Influenster and OGX.

[This review was collected as part of a promotion.] I enjoy this shampoo. I love the scent, I would describe it as coconutty, earthy. It definitely keeps my hair feeling clean for 2-3 days. I like the color of the bottle and it is easy and pleasant to use.

[This review was collected as part of a promotion.] OGX Biotin and Collagen Shampoo smells good. It contains vitamin B7, biotin, collagen, and hydrolyzed wheat protein which helps to give volume to hair. My hair has issue with hair thinning so i definitely need volume in hair. And this shampoo is good in that regard. But I felt that it made my hair felt little drier and also I faced lots of hair fall during hair wash. This shampoo is great for oily scalp or people who do less hair was in a week.

[This review was collected as part of a promotion.] I really like the. biotin & collagen shampoo it gives my hair the boost it needs to feel fuller. The packaging itself is the same as the other ogx shampoos just different colors. I think price wise they are about average for shampoo. I think this is definitely worth trying. It cleans my hair without stripping it of everything my hair has to give. My hair is brittle already but this shampoo cleans it without making my hair worse.

Not such a great experience. The ingredients are not natural and you can’t even see the back of the bottle. It clearly states on the back of the bottle “to create fuller looking, skinny hair.” It gives you the illusion of thick hair it can’t actually claim it will make your hair fuller because it can’t. It’s like a bad boyfriend, looks great at first but after investment a terrible terrible idea later.

[This review was collected as part of a promotion.] I received OGX Biotin & Collagen Shampoo free for review from Influenster and OGX. I love the scent and that it doesn't stay strong like other brands. My hair has had a little more volume since I started using it. I recommend.

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.] I was pleasantly surprised by this shampoo! When you first pour some out, it’s very thick! Which seemed weird until I used it more. It lathers really well and smells like expensive shampoo. I noticed a difference after just a few weeks. My hair didn’t get greasy and it felt more full. Definitely worth the price!

Recently I developed a Thyroid problem and was losing quite a bit of hair with every shower. Tired of my thinning hair, I purchased this shampoo/conditioner after finding it on a list of best hair thickening shampoos. After using for 2 weeks now, my hair is no longer thin and I have not had any hair loss in the shower. I have been telling everyone I know and will continue to do so!
