Does your scalp itch? 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 excessive sebum or the use of aggressive products. They cause severe itching, and the more you scratch, the more irritated your scalp becomes.

Seborrheic dermatitis is a chronic inflammatory disease that manifests itself 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.
