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!!

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!

[This review was collected as part of a promotion.] I really wanted to like this shampoo but unfortunately my fine and color-treated hair did not respond well to it. I have dark brown hair and this brought out a ton of red in my hair. It also made it super oily after not even a day (I can usually go 2-3 days without washing with other shampoos). It does smell great and made my hair super soft! If you have medium to thick hair that isn’t color treated I would definitely recommend trying this!

I am a big fan of OGX products. It all started with the Argan oil shampoo. But I wanted to branch out and try something new. So I opted for the thick & full biotin & collagen shampoo. Normally, I have thin straight hair. But this shampoo helped strengthen it. I would definitely recommend it to others with weak, thin hair.

[This review was collected as part of a promotion.] Really good products !I live how clean my hair feels after using the shampoo. I didn’t notice any strong scent and the shampoo been clear gives me the confidence that the product doesn’t have a lot of chemicals . I really recommend using it

I can't express my love for this product enough. For years I have been trying to find a shampoo that will thicken my hair and make it lengthy and healthy. This is the first product I have found that actually works, and doesn't build up. Thank you OGX for such an amazing product.

[This review was collected as part of a promotion.] This shampoo washes my hair leaving it clean without making it dry. I like the packaging for the shampoo and absolutely love the smell! I also appreciate the fact I don’t have to spend so much money on a product I’m using all the time on a lot of hair.

Ever since I started using this product ( shampoo & conditioner ) my hair has grown so much . My natural hair used to be curly , and from applying heat to it over the years , the curls have become less defined . But ! The collegian and biotin are really helping my curls come back! Deff recommend this product if you have damaged curly hair . ( p.s A little goes a long way )

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!

I bought the travel size bottles at first to use on a vacation and I absolutely fell in love with it!! I immediately bought full size when I got home. I have long curly dry hair and this was amazing. It left my hair soft and light. Most shampoos and conditioners weigh down my hair but this does not!! My hair is less frizzy and with way more volume!!
