I live by this stuff!!
Hands down THIS is the best thing out there for curly hair in my opinion! Aveda has an entire line for curly hair and I use every single product! I've searched for years and finally a great shampoo and conditioner! S&C go for about $20 each, but so worth it.
I really like Aveda's Be Curly line. I know a lot of curly girls like to wear their hair straight, but for days when you want to flaunt your curls or waves (or just can't be bothered), this shampoo and conditioner are just what you need. My own hair dries into loose waves and curls that tend to frizz, but Be Curly fights frizz and enhances curl, so after using it my hair dries into gorgeous, loose ringlets. For the absolute best results, I suggest working Be Curly style prep and Be Curly curl enhancer into your hair while it's still damp, then gently drying with a diffuser.
