What aspect of hair health does Trichology primarily focus on?

Trichology is the scientific study of hair and scalp health, specifically focusing on diseases and disorders affecting them. This field of study examines various conditions that can impact hair growth, hair loss, and scalp health, such as alopecia, dandruff, and other dermatological issues. Trichologists are trained to diagnose these conditions and often work in conjunction with dermatologists to provide comprehensive care.

In contrast, design and styling pertain to the aesthetic aspects of hair, including haircuts and styling techniques, which are not the primary focus of trichology. Growth and maintenance relate more to how to care for and nurture hair rather than specifically addressing health issues. Finally, coloring techniques are part of the cosmetic enhancement of hair, which falls outside the purview of trichology's focus on health and diseases. Thus, the emphasis on diseases and disorders makes it clear why this option is the central tenet of trichology.
