Trichology is a branch of medicine concerned with the study of structure, functions and diseases of hair and scalp. Trichology often requires interactions with endocrinology, gynaecology, internal medicine, pediatrics, pathology and psychiatry.
Hair is an important appendage and an internal organ of the cutaneous system. As systemic diseases are reflected in the skin, hair also reflects and reacts promptly to systemic insults. Hair disorders can give clue to many enigmatic genetic syndromes. Hence the knowledge of basic and clinical dermatology is essential to set up a trichology practice.
