A practical guide to the standardization of hair loss photography for clinicians.

The article focuses on the development of novel, pragmatic, and flexible standardized photography protocols for the clinical assessment and monitoring of hair loss disorders. Three main protocols address common hair loss presentations: pattern hair loss (using Hamilton–Norwood and Sinclair scales), frontal fibrosing alopecia/traction alopecia (incorporating FFASI, FFASS, ALODEXFFA, and M-TAS scores), and alopecia areata and other patchy hair loss conditions (utilizing SALT, ALBAS, LPPAI, and other validated scoring systems). These protocols provide detailed guidance on photographic views, hair positioning, and trichoscopic imaging to ensure reproducible, high-quality images that can be used by clinicians and medical photographers even without formal photography units. The standardized approach aims to improve objective assessment, patient monitoring, and research comparability while acknowledging practical challenges such as hair type variability and patient comfort.
