The study of hair and its diseases is called "trichology." Trichology is a specialized field within dermatology that focuses on the scientific study of hair and scalp health. Trichologists are professionals who are trained to understand the structure, function, and growth cycles of hair, as well as the various factors that can affect hair health and lead to hair and scalp disorders.
Trichologists may work in various settings, including hair clinics, salons, and dermatology practices. They assess and diagnose hair and scalp conditions, provide advice on hair care and treatments, and may recommend products or therapies to address specific issues like hair loss, dandruff, scalp irritation, and other hair-related concerns.
