You can wash your hair in the morning, but with warm water. If there is more dandruff, it can be combined with selenium disulfide lotion. If a small rash like erythema or papule appears, topical trimethoprim cream or paregoric ointment can be used. If a rash with pustules appears, topical clindamycin phosphate gel can be used, and if the patient has intense itching, oral levocetirizine hydrochloride capsules can be taken. The patient needs to avoid spicy and irritating diet such as raw onion, raw garlic, strong tea, coffee, chili, mustard, and also avoid drinking alcohol, avoid eating too much greasy food, maintain good rest and sleep, and eat more vitamin-rich vegetables for adjustment and treatment.
