Leaves my hair feeling super clean. This is the only shampoo I have used that has not left my hair feeling super dry and weighed down. Not to mention it smells really good. I have been using this shampoo for almost 5-6 months. (Pics of curls on wash days)

I used to really like this shampoo but then I realized that it was creating so much buildup in my hair that made my hair feel kind of waxy. I was so sad because I have been using this shampoo religiously for about 6 years and it makes my hair feel even thicker.

This stuff has made my hair feel so much thicker. I like the way it smells. I notice that my hair doesn’t feel as thick when I use a different shampoo/conditioner, which makes sense because I don’t think this actually makes your hair thicker, just makes it look and feel thicker, which is good enough for me.

Most products always give that same disclaimer "It works on the first try" but this product actually means it! I have ALWAYS had thin hair so after reading the good reviews, I decided to try this out. I've always had the shampoos that smelled good but my hair was still limp. NOT with this product. When it says you'll see results after the first use, it's true. As soon as I used the shampoo and conditioner, I blow dried it and could instantly tell the difference. After the second time, there was no doubt that my hair appeared much fuller than before. And it smells great so it's even better. And think about it...a product that actually works, that's more than HALF the price of these other fancy products that don't even come close!! BUY THIS!

[This review was collected as part of a promotion.] This shampoo has all the effectiveness of a pricier shampoo, but without breaking the budget! It has a luxurious scent, and the lather is perfect. The bottle is perfect to hold in the shower without slipping out my hands. I love it, my hair feels thicker and fuller after using this shampoo!

[This review was collected as part of a promotion.] Absolutely love these OGX products. The bottle shape is so cute and the fun colors make it really fun to try out all of the different collections. The biotin and collagen set, specifically, make my hair feel so soft and noticeably shiner after use.

[This review was collected as part of a promotion.] I received this OGX Biotin and Collagen Shampoo for free through Influenster in exchange for my honest review. I really like this shampoo, it lathers really well. It smells amazing and leaves my hair looking great. I would definitely recommend this product.

I've been using this product for almost 2 years now and I absolutely love it! I've used other products by this company, but this is by far my favorite. I have naturally wavy, dry, thick, and coarse hair. This leaves it feeling silky smooth and refreshed. This is my go to hair product.

I thought I will never find the one when it comes to shampoos. Well, this is it guys. I do not know what they did to this one in specific, but it leaves my skin so smooth after washing. The volume of my hair is great as well. And I used to always struggle with it. It does have a slight purple color (especially the conditioner one), which works great for keeping my blonde highlights without yellow tones

This is my everyday shampoo I also use their conditioner. I LOVE their shampoo and conditioner so much it has the best fragrance which the scent stays in your hair, I get compliments about the way my hair smells all the time!! my hair is so soft and it has made my hair less oily over time in my opinion. you wont regret buying this product it has made showering more exciting because who doesn’t love using a amazing product in the shower?!
