What is the primary focus of trichology?

Trichology is a specialized field within the cosmetology industry that focuses on the study of hair and scalp health. This discipline encompasses understanding the anatomy and physiology of hair and the scalp, as well as diagnosing and addressing various hair and scalp conditions. Trichologists examine issues such as hair loss, scalp disorders, and other related health problems, providing insights and solutions to promote healthier hair and scalp.

While the other options may touch on aspects related to hair, they don't encompass the comprehensive approach that trichology takes towards diagnosing and treating hair and scalp health. For instance, studying hair styling techniques pertains more to the practical application of aesthetics rather than health. Analyzing color pigments in hair is a facet of color theory but does not cover the health aspect. Developing hair products mainly focuses on formulation rather than the underlying health concerns associated with hair and scalp. Therefore, the primary focus of trichology lies in understanding and improving the health of hair and the scalp itself.
