crépu

frizzy, fuzzy; kinky (for hair)

“Rosalie avait des cheveux crépus, gris-blanc, qui dressait comme une toque au-dessus de son crâne.” — Rosalie had frizzy greyish-black hair, which stood up like a judge's wig on top of her skull.

From Old French cresp + -u; ultimately from Latin crispus (“curly; crimped”) (→ crêpe).
