By far my favorite shampoo. I have thin, fine hair, so I always struggle with volume. Most shampoos weigh my hair down. This one boosts the volume with biotin just like it advertises. An absolute 10/10.

I love it because it doesnt leave my hair dry and because I have treated hair sometimes it doesnt look healthy but these shampoo has helped me a lot with it because of the Biotin And Collagen

This is a great shampoo and I felt my hair feel thicker and healthier after using! I could notice a difference in the first month. I didnt notice an increase in length and this product does contain sulfates

I hate shampooing my hair because my hair become dry and unmanageable. This shampoo leaving my hair moist and you don't have to use so much for a good clean. I love the price, the smell and how much volume I had. FYI I'm fully natural with kinky hair type. Please buy with conditioner. both products together creates soft manageable hair! I love love love it! follow me on ig: blurasberrii

My daughter loved the way this shampoo & conditioner made her hair look and feel, but then she developed dandruff. This leaves me questioning: is it dandruff, product build-up, or what? Anyone else have a similar experience? Now we don’t know what to do to get her hair back to normal.

[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.

' I'm not one to really write reviews but I am one that reads and use reviews to help me decide. This is my honest opinion. I have long hair and it's very hard to keep it nourished towards the ends. I used a cheaper version of this type of product and I had good results. I tried the OGX product and absolutely fell in love within one use. My hair felt thicker softer smoother everything. I have now been using this product for two weeks and my hair is like unbelievably soft and bouncy full of body. Shiny healthy

From first use, I noticed a remarkable improvement in my hair, both in scalp coverage ands volume. I have been suffering from thin hair and balding for some time and your biotin/collagen shampoo certainly works for me. I also had no adverse allergic reaction, of which I do have to be careful. Thank you for a wonderful product. Highly recommended.

Mi cabello es ondulado, un poco seco y diria que muchas veces no es manejable. Hasta que un dia encontre este maravilloso shampoo que cambio totalmente mi cabello. El acondicionador y el shampoo es la convinacion perfecta para mi cabello. Y lo mejor de todo que no usan animales para probarlos..

[This review was collected as part of a promotion.] Biotin & Collagen Shampoo is an amazing shampoo , the effectiveness feels instant but more noticeable the more you use it . The scent is addictive and the packaging being the shape that the bottles are help with knowing what to look for. The price is worth the product and the shampoo leaves your hair smooth and clean.
