I have very thin hair and this product gives me more volume without getting tangled and gives me great shine. The smell is amazing and it lathers well in the shower. I use the large pump bottles so it lasts me longer!

I think this product is a good amount for the quality youre getting. It worked for my blonde colored hair. The sent isnt very strong but if you dont like very strong smell then Id recommend for you.

While using in the shower, you can immediately feel that your hair is thicker and more full. U barely need to use any and the smell is wonderful. I used both the shampoo and conditioner but I believe the shampoo shows the most results

Been using the thickening biotin and collagen shampoo and conditioner for about one year and still love the results. My hair is thin and limp and this brings it back to life!! Absolutely love and will continue to use.

As a professional hairdresser drugstore shampoo and conditioner are out of the question. BUT OGX is the only one I will reach for in a need for a clean and good shampoo

[This review was collected as part of a promotion.] Love this brand! It makes my curly hair soft and less frizzy. The smell is also great and it is pretty good for the price. I will definitely be purchasing this again.

[This review was collected as part of a promotion.] Love it the packaging and texture and scent is so amazing the effectiveness is so good too and the value of money it is good too love how it makes my hair

It was good at first, but then my hair was really awful and I was very sad with the results. However, it depends on the type of hair but I did not like it

My mom loves it. She thinks it really helped her when her hair was shedding. I have naturally curly hair and also use it at times and have no complaints. Anything with biotin and collagen, is a go for me.

I used in conjunction with the shampoo. Seemed to work well enough although I never noticed it helping with the strength of my very fine, thin and fragile hair.
