Crepe hair, also called wool crepe hair is a product used to create simple hair and fur effects. It is most commonly used for beards, eyebrows, or other simple body hair.

Crepe hair traditionally is sold wrapped in a tight braid that unravles wavey. It may then be straightened with a cool iron if desired. The Crepe is then applied in a buildup fashion, starting at the base (according to the desired directional grain of the hair), and building up. It is adhered to the skin using spirit gum or liquid latex. After applying the hair, it may be trimmed and styled as desired.

Crepe hair is sold in a wide variety of colors.
