To treat seborrheic dermatitis
of scalp, use a ketoconazole
based shampoo every alternate days. Also use a steroid and clotrimazole
based lotion over the scalp for faster resolution of the lesions. If the lesions are too itchy, you may also take antiallergic like cetirizine
. Do not oil your hair as it aggravates seborrheic dermatitis.
Hope that answers your query. Take care.
