Is your scalp itchy? Here are the main causes.

Main causes of itchy scalp

1 – Dandruff and seborrheic dermatitis: the most common causes.

Dandruff, those unsightly little white flakes, is often caused by excess sebum or the use of harsh products. It causes intense itching, and the more you scratch, the more irritated your scalp becomes.

Seborrheic dermatitis is a chronic inflammatory condition that appears as red patches covered with thick, yellowish scales. In addition to the scalp, it can also affect the eyebrows, the area behind the ears, and even the nostrils.
