What does Tricology primarily focus on?

Trichology primarily focuses on hair, specifically the study of the hair and scalp. This branch of science looks into various aspects such as hair growth, hair loss, and scalp conditions. Trichologists analyze the biological and physiological factors affecting hair, diagnosing issues like alopecia (hair loss), and recommending treatments for various hair and scalp conditions.

While the other options relate to important aspects of esthetics—such as skin health and nail care—trichology is distinctly centered around hair. This specialization requires an understanding of hair structure, hair follicle health, and the impact of environmental factors on hair. Additionally, scalp treatments might seem relevant, but they actually fall under the broader umbrella of trichology, which encompasses overall hair health and treatment.
