I love this shampoo. It smells amazing and it does not make my hair feel weighted down. I do not think you could improve this product. It last all day.

[This review was collected as part of a promotion.] I like the smell of this shampoo! Leaves my hair feeling clean and hydrated. I’m always looking for new thickening products as my hair has thinned over the years, seemed to help add some volume

A little bit goes a long way, within a few weeks i already seen hair growth and it smells really good, i would improve the texture that the shampoo leaves your hair almost like it dries your hair out.

This is my go to for summer hair. It smells amazing first of all. It's ultra nourishing . It makes my hair stronger and grow with less splits. I love this stuff.

I wouldn't say this lengthened my hair, but it did make fuller. After having my daughter 6 years ago, I lost a ton of hair. This helped a bit, along changing up vitamins and diet. My feelings about this is neutral

I can not stress enough how important biotin is to your natural hair growth! This was the very first kind I purchased when I started my natural hair journey. I used it for 3 months and it made my hair look and feel a million and 3 times better.

Ok so I have curly hair and even tho this product doesn’t say its for curly hair it makes my hair feel amazing. My hair was super moisturized and curls were defined I would 100% recommend

This has become my favorite conditioner! It leaves my hair silky smooth and smelling beautiful. I feel like this particular version keeps my hair strong and healthy. I’ve tried many of the Ogx products and they are all great!

[This review was collected as part of a promotion.] I received the ogx biotin & collagen shampoo complimentary for an honest review. The shampoo cleansed effectively, the scent is subtle but nice, and it left my hair feeling clean and soft.

I have used this shampoo and it's sister conditioner for about a month now and have seen huge improvement in my hair. My hair is softer, fuller, and thicker. It's given my hair manageability, too.
