Although you can accurately call the person who cuts your hair your "trichologist" if you want to, the term is usually applied as it is in our example sentence: 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").
