'Hairdo archaeologist' solves ancient fashion mystery
Janet Stephens earns a living trimming, straightening and dyeing the hair of customers seeking the latest look.
But the stylist from the US city of Baltimore is more interested in the hairdos of the past.
Stephens is a hairstyle archaeologist who specialises in recreating how women in ancient Rome and Greece wore their hair.
She spoke to the BBC about a museum visit that marked the start of a long journey of discovery on which she solved a historical mystery and had her work published in an academic journal.
