1. Eczema: Eczema may be caused by the patient's head sweating heavily and not being dried in time, resulting in the scalp being in a humid environment for a long time. It may also be that the scalp is exposed to allergens, which will cause red papules on the scalp, accompanied by obvious itching symptoms, leading to itching of the scalp. You can apply antipruritic drugs such as calamine lotion and diphenhydramine cream according to your doctor's advice. If the scalp itching is serious, you can take loratadine tablets and cetirizine hydrochloride tablets.
2. Tinea capitis: Tinea capitis is caused by skin fungi infecting scalp and hair. Scales may appear locally on the scalp, accompanied by alopecia and scalp itching. Debris will appear after scratching by hand, which will make the patient's scalp itch. Topical application of antifungal drugs such as clotrimazole solution and miconazole nitrate gel, combined with itraconazole capsules and terbinafine hydrochloride tablets can relieve the discomfort caused by tinea capitis.
Patients should be careful not to scratch the scalp with their hands to avoid damaging the scalp.
