I recently used this shampoo when visiting relative. I was amazed at how thick my hair looked and my curls were back. As soon as I got home I ordered myself a bottle. Shipping was fast and the bottle was well packaged. No leaks.

I have been using this for about 2 weeks now and I immidiatly noticed the difference on the way my hair looks and feels. People have even asked me what I'm doing because my hair doesnt look as thin.

I've been using this for a little over a week and I haven't noticed any more thickness in my hair, but my hair now smells like doughnuts so that's a plus.

Very happy with results! Makes my very fine and thin hair more puffy and full looking! I don't even have to use Mouse when I use shampoo along with the conditioner! Huge bottle will last a really long time and so reasonably priced!

A cancer patient recommended this shampoo stating it helped her hair full thicker. Biotin & Collagen are 2 components that assist in hair growth. Great product

This product smells great! But I don’t love the way it makes my hair feel. It may just not be the best product for MY hair so I still have it a 4. It feels nice in my hands and it cleans well, my hair just doesn’t feel as nice once it is dry.

The product itself is excellent as far as a volume shampoo but the pump is easy to break in shipping and I had to call Sam's and get a replacement since the first shipment had the pump broken off (kudos to SAM'S Customer Service)

I have extremely thin hair and I have tried almost every shampoo but OGX biotin & collagen shampoo is amazing!! My hair is shinier than ever and it feels so soft and healthy.

s shampoo because I was losing so much hair. Currently using both the shampoo and conditioner, and it seems to be helping. I plan to keep using it and would recommend it.

I'm pretty impressed with this shampoo, like it well enough that I gave some to my daughter in law , because I felt she would also like it well enough to get it for herself.
