IPA: //ˌsɛbəˈriːɪk//
KK: /sɛbərˈhiːɪk/
Relating to a skin condition that causes oily or flaky skin, often affecting the scalp and face.
The doctor diagnosed her with seborrheic dermatitis, which caused her scalp to be itchy and flaky.
Seborrheic is formed from "sebum" (from Latin *sebum*, meaning fat or grease) and "-rrhea" (from Greek *rhein*, meaning to flow). The term describes a condition characterized by the flow or discharge of oily substances from the skin.
Think of 'sebum' as the oily substance and '-rrhea' as the flow — this helps you remember that seborrheic refers to a condition involving the flow of oil from the skin.
