The causes of itchy head and dandruff are different, and the removal methods are also different, as follows: 1. It may be seborrheic dermatitis in the scalp area, and after this symptom occurs, you can use compound ketoconazole hair lotion to wash your hair, or you can use selenium disulfide to wash your hair. If the itching is more obvious, you also need to take oral antihistamines, such as loratadine, epinastine, imipramine, etc.; 2. If the dandruff and head itching are very obvious, it may also be formed by fungal infection, such as ringworm, and this time you need to test for fungi. If it shows positive, oral antifungal medication is required, usually itraconazole, or terbinafine, etc. can be taken orally. Topical antifungal medications can also be used, such as compound ketoconazole ointment, etc. If itching symptoms are obvious, you can also take oral moistening and anti-itching capsules, etc.
