AVEDA has a really, really great serum - I don't know the exact name of the product but worked great the other day at the salon. I have struggled my entire life with extremely thick, frizzy, kinky hair. I've used straighteners, ethnic straighteners, and I regularly iron it if I am going to wear it down. It's HARD work let me tell you! I also use a foam made by Paul Mitchell - but honestly, I hate putting stuff in my hair...and I try not to wash it every day.
