A receding hairline is a distinctly masculine trait. Females can occasionally develop it in a condition called frontal fibrosing alopecia. However in females, this is not hereditary and is a variant of a condition called ‘lichen planopilaris’. Lonely hair is a clinical sign in this condition(1). What a cute name for a clinical sign!
