It might be caused by sebum, sweat, or stress!
Even though you wash your hair properly, you may experience itching, redness and inflammation, bumpy eczema, and peeling skin that falls onto your shoulders. Eczema that appears on the scalp and hairline, areas covered by hair, is called scalp eczema.
Scalp eczema has a wide variety of causes, including irritation from hair dyes and sweat, dry air, excessive shampooing, overwork, and stress, and symptoms can appear regardless of the season. Red bumps that form in the hair follicles of the scalp, where sebum secretion is high, cause itching, eventually turn into oily scabs, and dandruff becomes noticeable. One in six people * experience this problem, and some are so bothered by dandruff that they can't wear black clothes.

Scalp eczema often goes untreated until it becomes chronic. It's important to treat it properly with medication early on and make lifestyle changes to prevent future scalp problems!
