Seborrheic scalp cannot heal itself and is a common chronic inflammatory skin disease. Most patients with seborrheic dermatitis need anti-inflammatory and antiseptic treatment to get healed. Patients need to take scientific home care in daily life, together with topical and oral medications for treatment. The patient should regulate the diet, limit the fatty and sugary diet, avoid drinking alcohol and spicy and stimulating food; ensure a regular life; avoid excessive cleaning and rubbing; use a mild emollient to enhance oil control and moisturizing. In addition, under the guidance of a doctor, select medications. Topical medications mainly focus on fat dissolution, keratin exfoliation, anti-inflammatory and anti-itching, and different dosage forms can be selected according to different parts and lesions. It is important to receive treatment as soon as possible after suffering from seborrheic dermatitis, because when it is detected at an early stage, it can be treated very well, either through local medication or oral medication.
