Did you know?

Although you can accurately call the person who cuts your hair your "trichologist" if you want to, the term is usually applied to someone who studies and treats hair and scalp ailments. The "trich" in "trichologist" is the Greek trich-, stem of thrix, meaning "hair." This root makes an appearance in a number of other similarly technical-sounding words, such as "trichiasis" ("a turning inward of the eyelashes often causing irritation of the eyeball"), "trichome" ("an epidermal hair structure on a plant"), and "trichotillomania" ("an abnormal desire to pull out one's hair").
