Hair condition	Teletrichology visit evaluations	Instrument	Instrument findings
Telogen effluvium †	Pull test Hair shedding Ponytail measure	Macro‐imaging app/handheld microscope	Lack of hair shaft variability
Alopecia areata †	Pull test SALT PGA	Macro‐imaging app	Yellow dots Broken hairs Exclamation mark hairs

FFA §	Measure hairline distance from glabella	Macro‐imaging app/handheld microscope	Absence of vellus hair
CCCA ¶	Clinical pattern suggests diagnosis	Macro‐imaging app/handheld microscope	Hair shaft variability
Other scarring alopecias †	Patchy alopecia	Macro‐imaging app/handheld microscope	Absence of follicular openings and peripilar casts
