Seborrheic dermatitis of the scalp in children can be treated with general therapy to boost the immune system and can be treated with medication. The main causes of seborrheic dermatitis may have genetic reasons, their own dietary habits, lowered immunity as well as bacterial infection skin disease. You can maintain a healthy and regular life, get enough sleep, avoid a greasy and sugary diet, avoid excessive cleansing, and moisturize your skin with daily scientific moisturizers. If the inflammation is more serious, you can use the strong glucocorticoid topical, if there is a fungal infection you can use ketoconazole and other antifungal agents, and if there is severe itching you can use antihistamines such as loratadine tablets to sedate.
