Great shampoo! I have noticed just after a month of using that my hair feels thicker and healthier! I did not notice an increase in length after using these for over 6 months. I wish it did not contain any sulfates. Overall good product and affordable!

This product is thick and it smells great. I describe the sent to be something that you would think a clean baby smell like. This shampoo was very soapy and provided a great lathering. I immediately felted and seen the difference in comparison to often shampoos that I’ve used. i did purchase the conditioner however the store only had the smaller size at the time.

I have African-American fine hair that is wavy and curly. I had previously used Coconut Milk, Keratin, and the Brazilian Keratin shampoos, as well as the Keratin conditioner, by OGX. I had been eyeing the Biotin & Collagen one for months and decided to try it. Best decision because it has been the best shampoo and conditioner for my hair. I noticed a difference immediately with regards to my hair feeling thicker. I actually take biotin pills which help to thicken my hair, but this shampoo and conditioner have been AMAZING for adding more thickness. Even though I don't wash my hair daily, I use the conditioner on a daily basis by thinning it out a bit with a little water and applying it to my hair as well as wrap foam. Daily use of the conditioner keeps the natural softness of my hair without making it too soft and more frizzy. Wish there was some type of hair paste for this collection to help define curls.

I love OGX shampoos and conditioner. Not only do they smell great, but they also make my hair silky soft. After trying numerous different brands, I’ve finally found a shampoo I enjoy using. I haven’t used this for long so I don’t know if it is helping strengthen my hair yet, but I’ll keep an eye on it. This particular shampoo is a bit too perfumy for me, but since it makes my hair feel nice I don’t mind. The smell doesn’t last long.

The best shampoo by this brand. I love it so much, and I rarely ever use anything else. It truly does help strengthen your hair, and stimulates hair growth. When I use this shampoo, my hair grows almost twice as fast!! This means getting more haircuts, which I hate, but it’s definitely a good problem to have!

I like to use this condition to treat my hair every once in awhile. I don’t use it every time I wash my hair because it weighs it down a little. I use it when my hair is feeling dry and brittle, and it hydrates and leaves my hair feeling soft and looking shiny. This is a good brand I have tried a couple different kinds and they are all good so far! Smells great!

Love this product. Dealing with changes in hair from menopause was not fun for me...finally getting back to thicker fuller hair and not as much loss. When I had my hair cut last month my hairdresser even noticed...she said my hair is fuller and growing better than it has in a few years! My natural hair is straight and fine although I always had a lot of it till the last few years. My son inherited my hair and he is even using this product with much success!

I really like this shampoo. I have been using it all summer. It lathers on very nicely, lots of suds. Its a thicker shampoo then what i am used to. The smell is amazing. It makes my hair feel silky and soft! Even if i do not use a conditioner. I have thin hair that gets oily fast. And sometimes flaky scalp. This shampok did not make any of that worse.

I have a lot of fine hair, that can sometimes have the appearance of being thin since it is very fine. So I try to look for products that will volumize whenever possible! This product is really cost effective, and, in my experience, does have a positive impact on volumizing hair. The texture is somewhere in the middle of thick and runny, and smells absolutely amazing! I use it like a leave in and try to air dry whenever possible. This is a great go-to product for when I am looking for something that will get the job done at a more reasonable cost.

[This review was collected as part of a promotion.] I will only use OGX hair products ever again. They make something for every hair situation. I love the biotin and collagen, I have been growing my hair out and it has helped wonders. The tea tree and peppermint is awesome and made my hair smell like Christmas all winter and in the summer I like the coconut milk because it is so gentle after a day in the pool and Sun.
