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.
[5] Trichology includes subspecialties that deal either with certain diseases or diseases of certain parts of the hair.
