Itching of the scalp area is also evident with daily hair washing, and the skin appearance of the itchy area needs to be carefully observed. If there is a significant diffuse flushing with a lot of dandruff, seborrheic dermatitis is considered a possibility. This condition is associated with poor rest and sleep deprivation, and in some cases, with Malassezia infection. It is recommended to use selenium disulfide lotion or ketoconazole lotion to wash the head for some relief of this itching. If the itching in the scalp area is accompanied by obvious plaque-like lesions, a large amount of dandruff needs to be scratched by hand, and if obvious punctate bleeding can be seen, it can be considered that there is a possibility of psoriasis in the scalp area, so it causes obvious itching. It is recommended to choose to use fluticasone propionate cream with carbotriol ointment for comprehensive treatment.
