    TLDR Androgenetic alopecia is less common in Chilean Mapuche than Caucasians, but more common than Asians, with racial differences in prevalence and types.
    This study analyzed the frequency and clinical patterns of androgenetic alopecia (AGA) in Chilean Mapuche, a group of Amerindian people from southern Chile. The study included 231 patients, 88 males and 143 females, with two or more surnames of Mapuche origin. The percentage of AGA in men was 32.9% and in women, 8.29%. The study found a lower percentage of AGA in Chilean Mapuche compared to Caucasians, but it was higher than Asians. The similarities of AGA percentage and clinical patterns between Mapuche and Asians may support evidence of common anthropologic links. The study suggests that racial differences in AGA prevalence and clinical types exist.
