Summary
While the majority of patients seeking hair restoration surgery have androgenetic alopecia, surgeons must be able to properly identify patients with other etiologies of hair loss. An invaluable tool to aid in scalp examination that is fairly easy to learn is dermoscopy, which involves the interpretation of magnified scalp images to identify changes not visible with the naked eye and can quickly provide the clinician with important diagnostic clues. This modality can detect characteristic features of many hair loss conditions and, for example, aids in the differentiation of scarring from nonscarring alopecia, androgenetic alopecia from telogen effluvium or alopecia areata incognita, and classic alopecia areata from other patchy alopecias. When findings are equivocal or a scarring alopecia is suspected, scalp biopsy is indicated, and dermoscopy-guided localization is recommended as it has shown to significantly increase diagnostic yield.
