Psoriasis isn't contagious. You can't spread it to other parts of your own body, or to other people, simply by touching. Psoriasis typically goes through cycles. The symptoms can persist for weeks or months, followed by a break. Maintain a healthy weight.
Psoriasis occurs often in skin creases or folds.
Avoid scratching, rubbing or picking at the patches of psoriasis. Bathe daily to soak off the scales. Avoid hot water or harsh soap. Keep your skin moist. Use soaps, shampoos, cleansers or ointments containing coal tar or salicylic acid.
