I am a big fan of OGX products. It all started with the Argan oil shampoo. But I wanted to branch out and try something new. So I opted for the thick & full biotin & collagen shampoo. Normally, I have thin straight hair. But this shampoo helped strengthen it. I would definitely recommend it to others with weak, thin hair.

Usually I love this shampoo but this time not so much. I got half way thru the bottle and it’s just a giant ball of slime. It will not come out of the bottle. When I tried to wash my hair with it it left little balls of gel all over my head and I was forced to rewatch it with a different brand to get the balls out.

[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!

I love all of these shampoos and conditioners. This one in particular gives volume and fullness to your hair. If your hair is thin you definitely have to try this. All of these products smell amazing and they really do what it says on the bottle. I recommend all of these products because they are true to what their label says!

i have gone through numerous products to get my hair thicker. i have had thin hair since i can remember and this is the first product that has made a difference. immediately after the first use i felt the difference. i would recommend this product to anyone who is trying to make their hair thicker, and healthier.

This is my favorite cheap drug store brand of hair products. Every time I use this conditioner I notice my hair is silky smooth, has increased strength and smells AMAZING. I love this product mainly because it does not contain any sulfates. Collagen and biotin are also great for your hair, skin and nails which is a plus.

[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!

I love this shampoo & conditioner! It smells lovely and leaves my hair feeling so soft. I can usually go 2-3 days between washes (which is really good considering I workout and sweat nearly everyday). It’s not super pricey and you can find it at most drugstores!

I can't express my love for this product enough. For years I have been trying to find a shampoo that will thicken my hair and make it lengthy and healthy. This is the first product I have found that actually works, and doesn't build up. Thank you OGX for such an amazing product.

[This review was collected as part of a promotion.] After my weight loss surgey, I needed a good shampoo & conditioner that would protect my hair from the excessive shedding that weight loss surgery patients go through. I washed & conditioned my hair once/week for a year with OGX biotin & collagen & my hair has grown SO much & gotten A LOT thicker, healthier & shinier than it's ever been (it now takes me about 2 1/2 hours to wash, blow dry & flat iron my hair due to the growth & thickness). I never once experienced shedding & have now told all of my weight loss surgery friends about this product!
