Pathogenesis of androgenetic alopecia / 中华皮肤科杂志

ABSTRACT

Androgenetic alopecia (AGA) is the most common type of non-cicatricial alopecia.Many researches have indicated that the pathogenesis of AGA involves genetic background,abnormal metabolism of sex hormones and follicle miniaturization,hair follicle microintlammation and environmental factors.Among them,genetic susceptibility is the most important factor for the individual difference of AGA,and follicle miniaturization induced by abnormal sex hormone metabolism and/or hair follicle microinflammation is the last step in the occurrence of AGA.
