Waves, texture, fullness!
I am SO happy with this product. After each use my hair is full of texture and volume. I have wavy hair, but the waves have always been lackluster and sad, and usually fall and flatten as the day goes on. Not with Dallas, though! My hair is so flowy with beautiful waves. I've never had my hair react to a shampoo/conditioner like it does with Dallas. I'm a fan!

great
The standout feature is the Biotin. Unlike some "thickening" products that just coat the hair in wax to make it feel thicker, this duo focuses on strengthening the hair infrastructure. After one wash, hair feels noticeably "plumper" and has a much better grip for styling.

Problem finally solved!
After trying for years, and trying just about every product on the market that claimed it could help with my fine, lifeless hair, my hair stylist used R&CO products. All I can say is WOW! These products do everything they say they can do.
