Biotin Thickening Treatment

I have only used this once since just receiving a week ago. I thoroughly loved the results after just the one use and will continue to use. It’s truly a very unique treatment in every good sense of the word. Thanks so much for taking the time to produce this product.

Awesome!

I bought mine at the salon and it’s amazing! My hair is very fine and thin… I tried so many products and was sceptical… but this really works! You do have to hold it for full 5 min, then rinse off… I skip conditioner and use leave in from R&co on my ends only… then I use defending spray and style! It literally looks like I have so much more hair! Love it!
