Why is my scalp itchy?
Seborrheic dermatitis
According to American dermatologist Dr. Anna Chacon, one of the most common causes of scalp itchiness is seborrheic dermatitis. This inflammatory skin condition is characterized by red patches, dandruff, and flaky scales.
It develops when excess sebum encourages the overgrowth of yeasts that naturally live on the scalp. This triggers inflammation, redness, and a faster turnover of skin cells, leading to itching and visible flakes.Scalp massage tool
