In the majority of male androgenetic alopecia cases, a patient\u2019s history and clinical evaluation may be sufficient to establish the diagnosis, while for women, they should be supplemented with trichoscopy. Methods: The PubMed and Scopus databases were used to collate published studies and to analyze the most typical trichoscopic findings in patients diagnosed with androgenetic alopecia. A total of 34 articles were retrieved after exclusion. Results: The most common features identified using trichoscopy included hair diameter variability (94.07% of patients), vellus hairs (66.45%) and the peripilar sign (43.27%). Others, such as the honeycomb pattern, yellow and white dots, were less relevant. Conclusions: We concluded that hair diameter variability, vellus hairs and the peripilar sign represented valuable indicators for the diagnosis of androgenetic alopecia.<\/jats:p>","DOI":"10.3390\/jcm13071962","type":"journal-article","created":{"date-parts":[[2024,3,28]],"date-time":"2024-03-28T12:09:40Z","timestamp":1711627780000},"page":"1962","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Trichoscopy of Androgenetic Alopecia: A Systematic Review"],"prefix":"10.3390","volume":"13","author":[{"given":"Agata","family":"Kuczara","sequence":"first","affiliation":[{"name":"Department of Dermatology, Medical University of Warsaw, Koszykowa 82a, 02-008 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Wa\u015bkiel-Burnat","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Medical University of Warsaw, Koszykowa 82a, 02-008 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriana","family":"Rakowska","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Medical University of Warsaw, Koszykowa 82a, 02-008 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u0142gorzata","family":"Olszewska","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Medical University of Warsaw, Koszykowa 82a, 02-008 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lidia","family":"Rudnicka","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Medical University of Warsaw, Koszykowa 82a, 02-008 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"622","DOI":"10.23736\/S0392-0488.19.06399-5","article-title":"Androgenetic alopecia in women and men: Italian guidelines adapted from European Dermatology Forum\/European Academy of Dermatology and Venereology guidelines","volume":"155","author":"Alessandrini","year":"2020","journal-title":"G.
