However, whether androgenetic alopecia causes changes in microcirculation is unknown.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n The objective of the study was to investigate whether alterations in nailfold capillaries occur in androgenetic alopecia patients.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n The nailfold capillaroscopy images of androgenetic alopecia patients and matched controls were collected and analyzed.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The frequencies of avascular areas, dilated, bushy and bizarre capillaries and capillary disorganization, nailfold capillaroscopy scores of 2 or scores both 2 and 3 were significantly higher in the androgenetic alopecia group than in the healthy controls (9.0% vs. 0%, 57.7% vs. 19.2%, 3.8% vs. 0%, 2.8% vs. 1.3%, 3.8% vs. 0%, 38.5% vs. 12.8% and 39.7% vs. 12.8%, respectively).<\/jats:p>\n <\/jats:sec>\n \n Limitations<\/jats:title>\n The results of this study may be biased on account of the limited sample size or the presence of an undiagnosed disease in participants which could alter the nailfold capillaries.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Bushy, bizarre and dilated capillaries, capillary disorganization, avascular areas and nailfold capillaroscopy scores of 2 or 2 and 3 were more common in androgenetic alopecia patients than in healthy controls.
