I was pleasantly surprised at how well this line worked to add substantial volume to my hair. Maybe volumizing conditioners that I've tried don't do much to nourish and moisturize hair but this one does both flawlessly! And it smells absolutely amazing.

I love this OGX biotin and collagen shampoo. It smells so good. I was worried this shampoo was gonna make my hair more oily than it already is. That was not the case. It made my hair so soft and shiny. It made it bouncy and much healthier looking. It is really nice. Definitely recommend

If your hair is flat and fine, but you dream of thick and full hair, look no more. This product will make your hair look and feel fuller and it smells amazing. Also is a cheaper option over salon shampoos and I even prefer it to the prestigious brands

I like the scent of this shampoo. I always felt that my hair was thoroughly cleaned. It lathers well and doesn't require much product. Although I never really noticed a difference in the strength or length of hair while using. Overall I probably wouldn't buy again.

I recently tried OGX Thick & Full + Biotin & Collagen Volumizing Shampoo, and I absolutely love it! This nutrient-infused formula provides incredible volume and body that lasts for over 72 hours. The sulfate-free surfactants make it gentle on my hair, while the Vitamin B7 Biotin works wonders for my locks. I highly recommend it for anyone looking to elevate their hair game!

Ooohhh I never get tired of this stuff! I'm always looking to find something good for my hair, and stuff is fantastic! It provides it with nutrients that keep it happy and healthy. With curly hair like mine, using shampoos and conditioners that aren't specifically for curly hair is always a risky game, but if you use the right products after washing, it truly doesn't make a difference (at least for me)!

This shampoo is amazing for helping grow long and healthy hair. I used this on a missions trip to the Dominican Republic, and man did it help my hair still look amazing after a full day of construction in the middle of June! It rinses out easily without leaving my hair feeling weighed down. This is a must for everyone!!

If there were more than 5 stars this shampoo would easily get it. I have always had very oily hair and no matter what shampoo and conditioner I used my hair would get oily by the end of the day and I would HAVE to wash it or it would get even worse the longer I waited. I purchased this shampoo with the conditioner on a whim because I have straight and thin hair so any kind of volume to give it some life sounds great to me and I've used other volumizing products and they have done nothing for my hair. After just the first time using it I could feel my hair already thicker and on top of that it did not get oily whatsoever even after more than 24 hours which never happens for my hair. I immediately went out and bought the bigger size so I won't run out 10/10 recommend!

Ive been using this shampoo for the past 3 months and I love it , I was having a really bad time due to hair fall out every time I would brush and shower I would get hand fulls of hair fall out but since I started using this I only see by most 5 hairs fall in the shower. Im very happy with this and totally will continue to use it.

This was an okay conditioner. I bought it because of the biotin and collagen additives because I needed something to strengthen my hair. It might've slightly helped in that department, but I wasn't too thrilled at how my hair would feel afterwards. It wasn't as soft as I'd like it to feel. If you're looking for softness and manageability, this isn't it.
