What does trichology study?

Trichology is the scientific study of hair and its diseases. This sub-specialty of dermatology focuses on various aspects of hair, including its structure, growth, and health. Trichologists are trained to address problems related to hair loss, scalp conditions, and overall hair care. Given that the primary subject of trichology is hair, it encompasses everything from hair anatomy to the effects of nutrition on hair health, making it a vital field for individuals seeking solutions to hair-related concerns.

While skin, nails, and glands are all important aspects of dermatological health, they fall under different branches of study. Skin is typically addressed in dermatology as a whole, nails have their own specialty known as onychology, and glands can relate to various organ systems and their functions, rather than specifically focusing on hair. Thus, the emphasis in this question on trichology firmly establishes hair as the correct focus.
