I have split ends & I use a flat iron on my hair alot. What Shampoo & Conditioner work best to repair my hair? Its not dry. But after I brush it, it still feels knotty but its not really (I don't know if that makes sense or not). I also have frizzy hair, so something that would help with that, too. Anybody know what kind of Shampoo and Conditioner would help my hair? Thank you!
