Have used this for years and loved it. Was able to wash my hair 3 times a week and it looked good every day. The new and improved is definitely not an improvement. It leaves my hair dry and frizzy the first day and flat and greasy the second. I don’t even understand how that’s possible! Guess it’s time to find another brand.

I bought this originally for my daughters' hair. It smells really nice and does seem to reduce the frizz in my eldest. She has coarse wavy to curly hair! I love that it doesnt have parabens and will probably start using this instead of redken for my own hair!

[This review was collected as part of a promotion.] The OGX Thick & Full + Biotin & Collagen Shampoo and Conditioner duo has been a game-changer for my hair care routine. The nutrient-infused formula truly delivers on its promise of adding volume and texture. After just a few uses, I noticed my hair felt thicker, more full-bodied, and had a beautiful shine. The subtle fragrance is also a nice touch, leaving my hair smelling fresh throughout the day. Plus, knowing that these products are sulfate-free and paraben-free gives me confidence that I’m using something that’s not only effective but also gentle on my hair. If you’re looking to add some volume and life to your hair, I highly recommend giving these products a try!

[This review was collected as part of a promotion.] I received this OGX thick + full biotin and collagen shampoo. This is a volume and texture shampoo and is nutrient infused formula with over 72 hours of volume and body!! My hair is shiny and flowing since I have started using this. I love that this is sulfate and paraban free! This helps protect hair protein bonds while cleaning thoroughly and giving your hair a younger looking and feeling touch! Love love love this. The scent is so good and it lasts untill your next wash.

I used this shampoo for years when I had shorter wavier hair. It's volumizing and was great for keeping my waves nice and bouncy. I stopped using it after I colored and grew my hair - it was slightly drying and I feel I needed something more hydrating and smoothening.

[This review was collected as part of a promotion.] Im in love with this product i have used this brand before with other different products they have. I love the smell of the shampoo and conditioner. Great packaging. It does the work it leave my hair so soft and shin. Definitely recommend this 2 products.

When I used this I was shocked! Ive been trying out different shampoos for years now and this shampoo is the one for me. My hair has gotten fuller, softer, and longer. The smell is amazing! And its long lasting. I really recommend this shampoo with the conditioner also!!!

[This review was collected as part of a promotion.] Love this biotin and collagen shampoo by ogx. It makes my hair feel nice and clean without over drying it or stripping too much moisture. It also suds up nicely and you don’t have to use too much for it to be effective.

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 ;)

[This review was collected as part of a promotion.] This shampoo is definitely moisturizing and makes my hair soft. I wouldn’t recommend it for oily scalps as it doesn’t give that “squeaky” clean feeling. Not a big fan of the sweet scent. I haven’t noticed any major hair growth.
