First of all I have very fine hair. From the first time I used it I loved it and my hair really looks and feels thicker. I am so happy I will be ordering this again.

I've been using this shampoo for about two weeks, and I really love it! It gives my hair noticeably more volume and makes it feel fuller without weighing it down. The texture is pleasant, it lathers nicely, and my hair feels clean, soft, and fresh after washing. I also love that it's sulfate-free. Overall, I'm very happy with the results and would definitely recommend this shampoo!

Works great if you have thin hair you can tell a difference between this product and others...I recommend The Shampoo and Conditioner.

Great shampoo. Only takes a small amount to give great sudsy shampoo. Leaves hair squeaky clean. Since I have been using this shampoo and conditioner, my hair has stopped coming out by the comb full.

This too I have been used this biotin shampoo for years and still been using it,I love this brand, it smell so good , it makes my hair so thick, and also is so shine with the (conditioner) combine these two make my hair so healthy. Thank ‘s to Sam’s club still carry this brand. Also the price at Sam’s club it very good price.

This shampoo, as well as the associated conditioner, has way too much perfume. If you're wearing actual perfume, it's overpowered. Also, it's hard to tell which is which in the shower... it would be smarter to put different colored pumps to make that easy. The shampoo works well though.

OGX Thick and Full Biotin and Collagen shampoo and conditioner for volume and texture. Purchased the shampoo and conditioner at my local drugstore. The products worked okay, but the fragrance (which I didn't care for) really bothered my nose, and my nose was still running even after I got of the shower. While I enjoy OGX products, this particular shampoo and conditioner are not for me.

I bought last week and I found my hair become rough, lifeless after using this shampoo. I was so hopeful before using this shampoo but after a couple of uses I experienced that this is the worst shampoo I have used. Hair are so lifeless, rough and sticky. I am very much disappointed. Total waste of money.

This shampoo does the whole opposite of what it claims to do. My daughter had very thick hair and ever since she started to use this shampoo, her hair has gotten so thin and breaks so much easier. My husband, son and myself noticed that as well, but my daughter was the most affected by it.
