What term refers to the study of hair and its functions?

The term that refers to the study of hair and its functions is tricology. This branch of science focuses specifically on the structure, function, and diseases of hair follicles and hair. Tricologists are experts who analyze hair and scalp conditions, treating issues such as hair loss or scalp disorders. This specialization is essential for professionals in the beauty and health industries, as it addresses both aesthetic and health-related concerns associated with hair.

Dermatology, on the other hand, deals with the skin, nails, and hair, but its primary focus is wider and does not concentrate exclusively on hair. Cosmetology encompasses all beauty treatments, including hair, skin, and nails, but does not specifically study hair alone. Esthetics focuses primarily on skin care, makeup, and other treatments related to the aesthetics of the skin, rather than on hair. Therefore, tricology distinctly identifies the study of hair and relates directly to its functions and health.
