Curly Girl Method

ToastieSimons

So after wearing my hair in a ponytail for years i'm trying to embrace my wavy/curly hair. Right now it's super wavy underneath but the top layer/front is just straight and frizzy.

I'm trying the curly girl, conditioner only method.  My hair is so greasy feeling on my scalp.  Any suggestions?  It's been about a week.  I actually pulled my hair back and put baby powder on my scalp today because it looks so gross. Would baking soda/vinegar wash be better than conditioner only?
