The scientific study of hair, its diseases, and care is known as trichology. This field focuses specifically on understanding the structure of hair, types of hair disorders, and appropriate treatments or methods for hair care. Trichologists are specialists who analyze hair and scalp conditions, providing insights into various issues such as hair loss, scalp diseases, and the overall health of hair.

Dermatology, while closely related, is a broader medical field that addresses skin, hair, and nail conditions but does not specifically focus on hair alone. Ophthalmology pertains to eye health and vision, making it irrelevant to this context. Cosmetology encompasses a wide range of beauty practices, including skin care, hair styling, and nail care, but does not specialize in the medical or scientific aspects of hair. Hence, trichology is the most precise term for the study specifically related to hair and its related issues.
