Causes of persistent scalp itching and seasonal irritation

Persistent scalp itching can be caused by various factors depending on the season. In winter, dry air from heating systems in cities like Sofia can lead to skin dryness. In summer, sweat, sun exposure, and frequent washing may trigger irritation.

When itching occurs year-round, it may indicate chronic inflammatory conditions, allergic reactions to specific hair products, or systemic health issues and deficiencies. Common conditions include seborrheic dermatitis, dandruff, and psoriasis. Experts suggest that instead of simply changing shampoos, individuals should seek medical evaluation to identify the underlying cause.
