Roughly half of people with psoriasis get scales on their scalp. Thick scales on your forehead, hairline, behind your ears, or on the back of your neck can be softened with coconut, olive, or peanut oil. Massage a small amount into your scalp, then put on a shower cap overnight, and shampoo in the morning. Repeat for two or three nights. The dead skin should soften and wash away.
You can use a comb to lift off the softened scale. Hold it almost flat, and gently move it in a circular motion. Don’t scrape your scalp.
