Trichology is the scientific study of hair and its diseases. This field focuses specifically on the structure, function, and pathology of hair, making it crucial for understanding various hair-related conditions and their treatments. Trichologists, the professionals who specialize in this field, often assess and recommend treatments for issues like hair loss, scalp disorders, and the overall health of hair.

The other subjects listed, such as nails, skincare, and facial structures, fall under different areas of study in cosmetology and dermatology. For example, nails are studied in onychology, skincare typically pertains to dermatology or esthetics, and facial structures may be addressed within the broader context of facial anatomy or cosmetic procedures. However, none of these disciplines specifically concern themselves with hair as the primary focus, which is why the correct answer is centered around hair in trichology.
