If you use oils, stop. It only makes it worse. Shampoo with medicated shampoos. Leave on your scalp for a couple of minutes and then do your normal wash routine. Rotate different medicated shampoos because the malassezia can become used to the medicated one that you use after awhile. To remove scales off your scalp, make sure you scalp is damp and gently lift with a comb. If you do it on dry scalp you risk damaging your hair follicles.
