Is it possible that leave-in conditioner makes my hair frizzy?
I suppose it could be due to other factors, but when I wash all the conditioner out of my hair (and still use styling products) my hair is actually less frizzy when it dries.
There are a few ingredients that some people can become frizzy from using, aloe vera, coconut, glycerin, and other humectants. This is especially true if t's humid where you live. Glycerin totally frizzes my hair. Try finding a leave in without glycerin or use a little oil on your ends when your hair is very wet.
