Answer

Signs of androgenetic alopecia include the following:

  • Gradual onset

  • Increased hair shedding

  • Transition in the involved areas from large, thick, pigmented terminal hairs to thinner, shorter, indeterminate hairs and finally to short, wispy, nonpigmented vellus hairs

  • End result can be an area of total denudation; this area varies from patient to patient and is usually most marked at the vertex

Diffuse alopecia areata may mimic the androgenetic form. The presence of exclamation point hairs, pitted nails, or a history of periodic regrowth or tapered fractures noted on hair counts suggests the diagnosis of diffuse alopecia areata.
