Aceves has three daughters, all of whom have been born with hypertrichosis. His eldest, Karla, is now in her early 20s. Her mother left when she was a baby and because her father was always away she was raised by her grandmother.

“It’s harder for the women because it’s less socially acceptable for a woman to be very hairy,” says Eva Aridjis. “Most of the women have been abandoned by the non-hairy partners that fathered their children. But for the men, they are actually considered virile and tend to have a lot of girlfriends.

“Karla is the only one in the family who has finished high school but she still has a hard time finding work.”
