Abstract
Alopecia is a challenging complaint dermatologists address. Traditionally, the evaluation consists of a thorough history, a physical exam that grossly evaluates the presence (or absence) of follicular ostia, perifollicular erythema, scaling, pustules, hair shaft abnormalities, laboratory evaluation, and if warranted a scalp biopsy. Although histopathological assessment is the gold standard in diagnosis, some refuse this diagnostic procedure due to the perceived invasive nature. Recognizing the value of dermoscopy in differentiating pigmented lesions, some dermatologists use dermoscopy to aid in distinguishing various hair disorders from one another.
