Favus; a skin disease causing scalp infections and patchy hair loss.

How it's used

Refers specifically to a fungal scalp infection that causes hair loss and crusty patches, often used to describe the appearance of the scalp rather than just the medical condition. It carries a strong negative connotation and is sometimes used as a derogatory label for someone with a messy or unkempt appearance. Unlike 鬼剃頭, which refers to alopecia areata caused by stress or autoimmune issues, 瘌痢 is infectious and typically associated with poor hygiene.

Examples

He had scabies when he was young, so there is a bald patch on the top of his head.

Common phrases

a person with a scabies-infected scalp

Common mistake

Do not confuse this with 鬼剃頭, which is sudden hair loss in circular patches without inflammation or crusting. Using 瘌痢 to describe someone's hair loss can be very offensive, so avoid using it as a casual descriptor for baldness.
