Skin conditions: why is my scalp itching?
Seborrheic dermatitis
Interviewed in the columns of Shape magazine, American dermatologist Dr. Anna Chacon identified factors that can cause scalp itching. First she mentions one of the most frequent causes of scalp itching: seborrheic dermatitis, an inflammatory skin disease characterized by the appearance of red patches covered with scales and dandruff. This condition is caused by sebum production, which favors the abnormal proliferation of yeasts naturally present on the skin and scalp. There’s an inflammatory reaction and redness, as well as accelerated renewal of scalp and skin cells.
Psoriasis
Other factors are less common but also cause scalp itching, including psoriasis. It’s an autoimmune disease that causes red patches and scales.
