A medical specialist or expert who studies and treats hair loss conditions and diseases of hair and scalp.
Formed from 'alopecia' plus the suffix '-ist' (one who practices or specializes in), following the standard medical terminology pattern established in the 19th and 20th centuries.
While 'trichologist' is the more common name for hair specialists today, 'alopecist' shows how medical language evolves—older term formations sometimes get replaced by newer ones even when they're perfectly descriptive.
