I have a little experience with oils when it comes to my hair. I have tried to use oils regularly but really do not see the use because it weighs my hair down. I do, however use oils as a hot oil treatment or prepoo and this works fine for me but... I have issues after my wash-n-gos with itchy scalp. So... my question is - how do you type 3 gals use oils in your hair? What ways are most effective?
