We’re launching a ‘mini-snaps’ series where we delve deep into particular topics and summarise the latest evidence and guidelines, through a handpicked search of the most relevant papers. This series, Root Cause, is all about alopecia. We're starting with the incredibly common, female pattern hair loss. On our website, you’ll find videos, handouts and lots of helpful resources.

But today, we kick off the series with a look at hair through history.
