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 the smell and texture of this shampoo. It makes my hair feel nice and think I have very fine hair and it's hard to make it feel volumized. After I use this and blow dry my hair, it feels a lot more luxurious and salon ready. I would definitely purchase this again!

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]

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.

This shampoo seriously surprised me in the best way. I started using it because my hair was feeling kinda flat and thin, and after just a few washes, I could actually feel more volume and bounce. 💜 What I loved: My hair feels thicker and fuller, especially at the roots Smells so good — kind of sweet and salon-y Doesn't leave buildup or feel too heavy

I have both the shampoo & conditioner. I've tried different brands but I feel this is the best and most safe. It's free of sulfates or para vena which is always important especially for treated color hair! I would recommend this to anyone my boyfriend also uses this

I love Ogx products. I interchange this one and the Moroccan oil to maintain strength and shine. It leaves your hair soft and has never weighed down my hair. Sls free and safe for color treated hair. The price is great and cost less than products that don't work. My hair is usually breaks easily but has become much stronger and healthier looking.

The OGX Thick Full + Biotin Collagen Shampoo and Conditioner really does give your hair that thick, and full feeling. The shampoo lathers nicely, and doesn't leave hair feeling stripped. The conditioner is a thinner consistency which makes it feel like you “need more”, but it does end up distributing nicely throughout your hair.

I really like OGX Biotin & Collagen Full Body Shampoo because it gives my hair a nice boost of volume without drying it out. It lathers well and has a pleasant, light scent that isn't overpowering. My hair feels cleaner and fuller after using it, but like the conditioner, it might be a bit heavy for fine hair. I also wish it didn't contain silicones, as I try to avoid buildup. Overall, it's a great option for adding body and thickness to thicker or coarser hair!

My husband with dry scalp and short hair loved this and I can see why. It leaves the hair silky soft and while it does weigh down the hair I can't be mad at it cause I swear my flat hair looks healthier than with some other conditioners. It is not a product that I would use all the time but I'm glad it lives in my shower.
