Trichophilia

Trichophilia, hair partialism, or hair fetishism is a paraphilia in which one becomes sexually aroused by, or is extremely fond of, human hair; commonly head hair.
Arousal may occur from imagery and physical contact of hair, this includes head hair, pubic hair, axillary hair and fur. Head hair arousal may come from watching or touching very long hair or shaved heads, hair cutting and head shaving, long bangs, red hair, wet hair, new hairstyles, permanent wave etc.
Long hair fetishism as well as haircut fetishism seems to be common, since there are hundreds of web sites and forums devoted to both these forms of fetishisms, based in countries around the world. Especially the haircut fetish is apparently a secret, largely unknown or little discussed by the media, or even acknowledged in Western culture.
