Publicly Available Large Language Models for Trichoscopy: A Head-to-Head Comparison with Dermatologists.

ABSTRACT: Background/Objectives: Trichoscopy is an important diagnostic tool for hair and scalp disorders, but it requires significant expertise. Publicly available large language models (LLMs) are becoming more popular among both physicians and patients, yet their usefulness in trichology is unknown.
