Buyer beware! This works as promised. When I use the shampoo I was not expecting the results that I got. My hair could definitely double for a lions mane or Diana Rosss hair once dried. This definitely make sure hair feel thick and fall as advertised. It leaves your hair filling clean and smelling really good, however there was just something about it that did not make this a favorite for me.

[This review was collected as part of a promotion.] OGX Biotin & Collagen Shampoo has been a delightful addition to my hair care routine. The shampoo lathers well and gives my hair a thorough cleanse without stripping it of natural oils. I have not noticed a significant improvement in the volume but with the texture I would say it feels soft after I use it. The subtle fragrance is a pleasant bonus that lingers without being overpowering. While it may not perform miracles, the results make it a reliable choice for me.

Great shampoo! I have noticed just after a month of using that my hair feels thicker and healthier! I did not notice an increase in length after using these for over 6 months. I wish it did not contain any sulfates. Overall good product and affordable!

I purchased a bottle of the thick and full and loved it. The second bottle the shampoo was so thick I could hardly get it out of the bottle. After using it and towel drying my hair I found gummy white pieces in my hair. I had to comb them out and wash with another kind of shampoo. What went wrong ? I have another bottle as I bought 2 at the same time. This is the lot number if it tells you anything . not happy with this bottle.LOT020205AA that 5 might be a S.

I like to use this condition to treat my hair every once in awhile. I don’t use it every time I wash my hair because it weighs it down a little. I use it when my hair is feeling dry and brittle, and it hydrates and leaves my hair feeling soft and looking shiny. This is a good brand I have tried a couple different kinds and they are all good so far! Smells great!

This is one of the few shampoos that actually gives my straight, thinner hair any volume!The plus is you don't need that much, as it's concentrated. The smell is nice and it leaves my hair soft and voluminous! If you're having trouble with other brands that claim to be volumizing, give this shampoo and conditioner a go!

[This review was collected as part of a promotion.] This smells amazing. I used to have really curly hair and due to the heat damage it has turned into strands. I noticed this gave my hair more volume. Not sure if I would use this for my kind of hair tho. Packaging is great and affordable. I just think this is more for people with really thin hair.

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.] I will only use OGX hair products ever again. They make something for every hair situation. I love the biotin and collagen, I have been growing my hair out and it has helped wonders. The tea tree and peppermint is awesome and made my hair smell like Christmas all winter and in the summer I like the coconut milk because it is so gentle after a day in the pool and Sun.

[This review was collected as part of a promotion.] Im always looking for hair products that work well with thick and curly hair and this shampoo is wonderful! It suds up really nicely and feels like im getting a good clean while not drying out my hair! The scent is also great!
