Hands down the best conditioner I have used. I’ve had trouble combing my hair Ever since I bleached my hair and dyed it. This conditioner leaves my hair soft and easy to comb. It doesn’t get tangly and I don’t have to deal with ripping my hair out while combing it. My hair also doesn’t look dry thanks to this conditioner. I LOVE this and HIGHLY recommend this. I always buy 2-3 at a time. Ogx Thick Full Biotin Collagen Shampoo 254 Oz Pack Of 2

I have a lot of trouble with off branded shampoos and some of them tend to make my hair dry. This product didn’t do that and made my hair feel soft. I would recommend this item to people who want soft luxurious hair. And I would continue to buy this.

I didnt have high expectations since its a drugstore brand, but wanted to give it a try. Its actually pretty good! I feel like my hair is fuller when I put it up. Im definitely going to buy it again. I dont love the initial smell out of the bottle. Its pretty strong. It fades quickly though.

[This review was collected as part of a promotion.] This shampoo was really gentle on my hair. I’m transitioning from all the hot tools and letting my hair natural. It’s been quite a journey but I’m shortly but slowly I’m finding the right products for my hair. I enjoyed using this shampoo it didn’t tangle my hair and it did a good job cleaning it.

One word FANTASTIC! My hair is kind of messy right now and Im losing a lot hair plus is friZZ I started to use this shampoo this week because I google best shampoos for weak hair and this one was in the list! One week is enough to know that this is an amazing product for hair! Highly recommend my hair now is beautiful

I have to constantly rotate the brand of shampoo/conditioner I use. This product and this bottle specifically is in my rotation. Not only does it smell good, it works extremely well with my thick, straight and dyed hair. I've tried other versions of the OGX shampoo/conditioner and this is my favorite.

[This review was collected as part of a promotion.] Biotin and collagen shampoo is a great shampoo, packaged well soap texture no smell very effective. This shampoo worked so well with my hair not real expensive. Definitely recommend made my hair, thicker soft and shiny. 

My favorite hair care product I own! I use both the shampoo and conditioner and my hair has dramatically gotten stronger! I also have noticed it become more fuller too. I have been using this product for over a year and I don’t plan on ever stopping!

I bought this about 2 months ago and it does do what it says, my hair has grown significantly since using this product and it makes my hair appear thicker, the only problem I have with this product is the smell. I'm switching to a different one with the same brand to try to get the same effect just with a better scent. I love OGX!

Most of my life I had very thin, brittle hair. It was strange because being African-American, we usually have coarse, thick hair. My mom cut ALL my hair off when I was about 13 because she said it wasn't growing and I needed to start fresh. About a year ago, I stop chemically relaxing my hair and straightening it. I got this shampoo and conditioner and since then my hair has done a complete 360! My hair is SO thick now. It has grown so much and is verg healthy! The little hair I had in my crown area is now full again. Thank you OGX! Holy grail for sure!!!
