I also have an oily scalp and here are some tings that I personally do to help control it
•washing my hair double (the first round is to remove buildup (for example; dry shampoo, sebum, dead skin cells…) and the second round is to focus on my scalp and deeply cleansing the roots of my hair)
•not tuching my hair (so the oil won’t spread)
•only using conditioner or treatments on the end of my hair
•chaning pillow cases frequently
•using a clarifying shampoo > moisturizing/hydrating
•only washing my hair 1 or 2 a week to train it
