Vinegar Rinse
If your hair tends to be oily even after you wash them, then first shampoo your hair and use a vinegar rinse. For this, mix 3 tablespoons of apple cider vinegar with 2 cups and wash your scalp and hair with it. This helps to get rid of excess oil on the scalp and on the hair. Also, it helps to restore back the pH balance, plus gives a light, bouncy texture to your hair.
