It is recommended to avoid eating a lot of spicy and stimulating food, fried food and sweets in daily life, so as not to cause the sebaceous glands to secrete more sebum and the face or scalp to become greasy. It is recommended to avoid excessive washing, which may lead to unbalanced sebum secretion, and to choose mild shampoo or cleansing products for washing. Eat fresh vegetables and fruits, ensure smooth bowel movements, and ensure sleep quality. If the symptoms of oiliness are heavy, accompanied by other symptoms such as itching and erythema, you can take oral vitamin A acid drugs for adjustment, such as vitamin E capsules and isotretinoin pills, but they should be applied under the guidance of a professional dermatologist.
