Trichology is the study of the hair and scalp.^[1] The term derives from Ancient Greek θρίξ (thríx), "hair"^[2] and -λογία -logia. In most jurisdictions the title of a trichologist, not the field of trichology, is considered a para-medical discipline.^[1]

The Institute of Trichologists was founded in 1902.^{[3] [4]} The first journal for the field, International Journal of Trichology, was founded in 2009.^[5]
