[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.

I am a type 2 diabetic that has had 3 types of cancer over the past years in my life. Having had radiation treatments many times, added with daily insulin, was taking a toll on my hair. Once thick and shiny, my hair had become thin and fine and somewhat dull and lifeless. I had been using your O2 shampoo and conditioner with great success. I have just tried your Biotin and Collagen products and I love them!! My hair feels thicker and it shines!!! Smells wonderful too! I'm a customer for life!! Thank you so much!!

[This review was collected as part of a promotion.] I’ve been using this product and love how my hair feels and looks after I blow it out. I have curly, fine hair and this has helped thicken it up. The scent smells very luxurious, kind of reminds me of a spa shampoo.

I thought I found my forever shampoo and conditioner. But now you went and changed the look and quality of the products. Why did you have to change perfection. My hair doesn't look or feel the same. Nor does it smell good. I'm so disappointed.. unless you change it back, I won't be buying your shampoo again..So sad.

I started using this product about 8 years ago! I love it because I have fine hair and it gives me so much body and makes my hair feel thicker and I love the fact that it's sulfate free! I also had weight loss surgery and it prevented me from losing my hair!

[This review was collected as part of a promotion.] I used this in combination with the conditioner. It leaves my hair shiny & smooth. It has a light coconut scent that is pleasant and not overpowering. I like the way it makes my hair feel, can’t comment on hair growth as I haven’t used it for long enough, but it’s definitely a great value for the price.

Most of the reviews were positive, so I decided to give it a try. I've been looking for a sulfate and paraben free shampoo that will give my hair volume. I wash my hair every 2 - 3 days and take good care of it. On the second use, I noticed a shocking amount of hair on my hands as I rinsed out the comditioner!! Thinking it might have been stress related, I used the shampoo and conditioner a third time. More hair fell out!! But the kicker was when my son decided to use the set after seeing the extra bottles in the hall closet. He yelled out from the shower and sticks his hand out with a clump of hair, and said, "Mom, look!!" Needless to say, I returned all 4 bottles the next day!! I worked so hard to stop the shed, and this horrible shampoo/conditioner was undoing all my progress. NO THANKS!

[This review was collected as part of a promotion.] Love it! It smells so good and made my hair so soft after just one wash. I would rate this five stars but my only issue is that it doesn’t really lather well in my hair so i feel like i need to use more.

[This review was collected as part of a promotion.] Ogx biotin & collagen shampoo is good for normal hair. I have an oily scalp and fine hair so it’s not the best for my scalp but my mom has normal scalp, tons of thick hair and she loves this shampoo and conditioner combo. It smells really good and I think it’s fairly priced. As you can see on the picture, my hair looks a little clumpy at the roots.

I am in love with this shampoo and conditioner! My hair was so thin and lifeless and now I have volume and thickness. Even my husband noticed a change. Please keep making amazing products. I have tried many and love them all and I love that they are sulfate free!!!
