OGX Thick & 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

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’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.

This shampoo has both healthy and unhealthy things in it. I don't usually use anything that has very many ingredients that I can't pronounce, but I tried this last year when my hair was thinning at a frightening rate. It smells good and lathers nicely. Very slowly my hair started regrowing, and several odd irritations on my scalp started healing. My hair never has and never will be thick. I did not expect miracles, so I was just glad when some hair started filling in. My only explanation is that the vitamins and protein it contains improved my scalp enough for viable hair roots to function again. Over the years I have noticed that B vitamins and eating more protein did help somewhat. This is why I thought maybe applying them directly to my scalp might be helpful. It seems that it is for me, so I just grit my teeth and try to forget what else is in there. Just bought 2 more bottles while it was on sale.

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!

LOVE,LOVE,LOVE this shampoo. It smells amazing & my hair is always soft & manageable. I've noticed a major difference in the thickness & health of it as well.

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.

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

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
