OGXThick & Full + Biotin Collagen Extra Strength Volumizing Shampoo with Vitamin B7 Hydrolyzed Wheat Protein for Fine Hair. Sulfate-Free Surfactants Thicker, Fuller Hair, 13 Fl Oz

I’ve been using this shampoo for a little under a year. I love the way it thickens my thinning hair. The softness and overall feeling of my hair is still getting better and better. The scent is really nice and a bit strong but you will get compliments. The price is affordable. The bottle could be a little more easy to squeeze but for sure a permanent shampoo & conditioner for me.

I’ve been using this for about a year, and I do see a difference in my hair feeling thicker and healthier. I’ve also noticed my thinning slowing down. Quality!

I have very fine, soft hair and in the last couple of years it's getting a bit thin, have lost some hair too, not happy about that. I recently tried this shampoo, it has a nice soft scent, barely noticeable. Not sure if it's had any effect on my hair as of yet but after reading the ingredients, I'll keep using it for the time being.

Fantastic product, hair is much better since starting using this, texture, feel, look is a lot better, damage hair is less noticeable, well continue to use it

I bought this for body and shine. I’ve spent a lot of money on expensive products that didn’t work. This stuff was amazing , it gave me body and shine like no other product did. Highly recommend

The price was good but it doesn't thicken like my other thicking shampoo and conditioner. This left my hair limp a few hours after using it but it did make my hair very soft. Now as for the smell, well not good, maybe it's the collagen not sure. I'll continue to use it since I bought it but I won't buy it again.

Seems to add some volume, reasonable considering price

Adds more volume to my thinning hair. Keeps it soft and shiny.
