I started using this to help my hair after treatment from cancer. It has made my hair so much fuller. My scalp isn't dry either. It has a wonderful smell as well. It lathers great. I would recommend to anyone that is looking to improve the fullness of their hair.

One of my favorite conditioners. It doesn't leave hair greasy once its rinsed out and smells soo good. It helped calm my frizz and did seem to give me a bit thicker hair if I blow dried it after.the scent last a long time. I will definitely continue to use it.

I love all OGX shampoo & conditioner. I've been using this one to replace my [product:kevin-murphy-plumping-rinse] as it's really expensive. My hair has been feeling super thick and way healthier. It's also sulfate and paraben free which is super important to me.

I use it currently, i love the way the product smells and makes my hair feel. I must say, the shampoo is a little dense but dont worry it works amazing. I have seen a difference in terms of growth i feel my hair has grown since using this shampoo BUT did not make it less dry. Had to use different products for that.

Leaves my hair feeling super clean. This is the only shampoo I have used that has not left my hair feeling super dry and weighed down. Not to mention it smells really good. I have been using this shampoo for almost 5-6 months. (Pics of curls on wash days)

This has been my holy grail shampoo!! Literally have gone through so many bottles. I tried other brands that claimed to do the same thing but it always felt as if my hair was weighed down. As soon as you use this shampoo-your hair will thank you. It instantly feels thicker and more full. Highly recommend this shampoo where it won't break the bank ;)

I love all OGX products, not only because they all smell amazing, but because they actually do exactly what they say they will! I used this shampoo for about three weeks and when I switched I could tell an immediate difference in the way my hair felt!

I really love the shampoo it smells amazing makes my hair nice and thick and full and healthy. It's great for the price and a great drugstore option when you don't want to spend a lot of money the whole brand has great options for hair care I just like this particular line from them

My FAVORITE SHAMPOO as of right now ! Because I like to switch it up every time I finish a bottle. It smells amazing. I can really feel my hair growing thicker and feeling softer. I would buy this again 10/10. [product:ogx-thick-full-biotin-collagen-shampoo-130-fl-ozpack-of-1]
