Resumo

A alopecia androgenética ou calvície em homens é caracterizada clinicamente pela rarefação simétrica de cabelos em couro cabeludo frontal e coroa. O desenvolvimento da alopecia androgenética é geneticamente determinado e dependente de andrógenos. Estima-se uma prevalência de alopecia androgenética em cerca de 50% dos homens brancos aos cinquenta anos de idade. Embora não traga consequências à saúde, a perda de cabelo pode interferir na qualidade de vida do indivíduo. A compreensão do ciclo de crescimento dos pelos e o conhecimento da patogênese da alopecia androgenética aumentou significativamente nos últimos anos, mas ainda não é completa. Folículos pré-programados do couro cabeludo sofrem um encurtamento dos ciclos de crescimento, associado ao afinamento da haste, processo denominado miniaturização do folículo. A herança genética suspeita é poligênica, mas, até o momento, apenas o gene receptor de andrógenos foi implicado nesta hereditariedade. Muitas opções terapêuticas estão disponíveis para alopecia androgenética masculina e são revisadas no artigo; entretanto, atualmente poucas demonstram resultados efetivos no tratamento da alopecia androgenética
