[This review was collected as part of a promotion.] A reliable shampoo for increasing volume to my hair! It’s perfect that the formula is made for 72 hours because I usually wash my hair about that time routinely. It doesn’t cause greasiness and didn’t harm my bayalage too severely.

I switch it up between the OGX keratin shampoo/conditioner and the OGX biotin and collagen shampoo/conditioner. I saw amazing results with my hair almost instantly that I've stuck with this brand and these products now for a few years and I would never go back to any other drug store brand.

If you have asian hair that is super straight and gets static-y during the cold like mine, I highly recommend this product. I use this along with the conditioner and my hair has never been so voluminous and full! This is my holy grail especially in the winter.

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.

[This review was collected as part of a promotion.] This shampoo smells great and makes my hair feel stronger after using it. I’ve seen this shampoo around for a while but never got around to trying it, and I’m sad I didn’t try it sooner. Works great for my hair and smells nice.

As a curly girl I love the slip this conditioner provides . I have low porosity hair and my hair drinks this up which is the main reason I love it . It's great for thinning hair making it stronger and shiny with the biotin and collagen . I really recommend it !

[This review was collected as part of a promotion.] I wish I could give this a great review. Only good thing I have to say is it’s a good smells dupe. Other than that, I am a candidate for good quality hair products and this is just not one of them. it makes your hair feel so rubbery

I bought this because of the good reviews and it was pretty cheap! I needed a volumizing shampoo because my hair is really thin and flat. It worked.. fine? I got out of the shower and my hair did seem more “volumized” but it was just fluffy and sorta dry. I had to use a hair serum after

Best conditioner for my color treated, radiation damaged hair. Helped my hair grow, strengthened it and the product smells great too. I go through a lot of conditioner. My curly hair used to be long and grow quickly but after radiation, I had a lot of damageand breakage which meant I had to cut it. It wasn't growing. I started using this shampoo and conditioner and it slowly started to grow again and became much softer.

I recently got my hair cut and the girl took more off then what I wanted. I researched and researched shampoos, oils, everything that would help hair growth. I came upon this shampoo. This is the best shampoo ever I have been using it for about 2 months and I am already seeing a huge difference. My hair is so healthy looking and it has already started hair growth. It's amazing the difference in just 2 weeks.
