The term that refers to the study of hair and scalp health is indeed trichology. This field specifically focuses on the diagnosis and treatment of hair and scalp conditions, including hair loss, dandruff, and other issues affecting the hair follicle and scalp environment. Trichologists are experts who understand how the hair and scalp function, as well as the various external and internal factors that can affect their health.

Dermatology, while related, is a broader field that encompasses the study of skin conditions, which includes not only the scalp but also all other areas of the skin. Cosmetology is more focused on beauty treatments, including hair styling, makeup, and skin care, rather than the medical or health aspects of hair and scalp. Ophthalmology is unrelated, as it pertains to the health and diseases of the eyes. Therefore, trichology is the most accurate term for the study specifically related to hair and scalp health.
