We aimed to document the HD\/cm2, number of hair shafts (HS) per pilosebaceous unit (PU), and HS diameter of different grades of anterior scalp margin MTA (AMTA). Methods: A cross-sectional descriptive study of 401 women over a 9-month period in 2023. The severity of AMTA was scored using the marginal traction alopecia severity score. Phototrichoscopic evaluation of HD\/cm2, HS diameter, and number of HS per PU was done on the alopecic intertemporal, right and left temporal, and the non-alopecic right temporal and intertemporal scalp sites. Results: The HD\/cm2 of the non-alopecic intertemporal scalp site ranged from 282 to 519 cm2 compared to that of the AMTA which ranged from 14 to 349\/cm2, p &lt; 0.001. With increasing severity of AMTA, there was a significant decrease in HD: grade 1 had HD of 227.56\/cm2 compared to 131.22\/cm2 in grade 4 at the intertemporal area, p &lt; 0.001. HS diameter ranged from 0.0087 to 0.0200 mm in grade 1 and 0.0078\u20130.0100 in grade 4. Single hair units were present in 100%. Conclusion: Anterior scalp marginal alopecia results in a significant reduction of HD, hair shaft diameter, and number of hair strands. Preventative education on hair care practices and hair styles is advocated. <\/jats:p>","DOI":"10.1159\/000543221","type":"journal-article","created":{"date-parts":[[2024,12,19]],"date-time":"2024-12-19T17:01:02Z","timestamp":1734627662000},"page":"207-214","source":"Crossref","is-referenced-by-count":1,"title":["A Comparative Cross-Sectional Study of Hair Density and Hair Shaft Diameter of Different Severities of Anterior Scalp Marginal Traction Alopecia in Women"],"prefix":"10.1159","volume":"11","author":[{"given":"Ehiaghe Lonia","family":"Anaba","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hadiza","family":"Sani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2024,12,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.4103\/jewd.jewd_17_21"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1002\/ski2.158"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1159\/000500509"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1473-2165.2007.00345.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.5070\/d325m840mz"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.4103\/ijdvl.IJDVL_553_16"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111\/ijd.13599"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.14974"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2023.02.024"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.4103\/JCAS.JCAS_50_16"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1684\/ejd.2015.2726"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.2147\/CCID.S394045"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1111\/jocd.14694"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1159\/000485522"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.4103\/ijd.IJD_648_20"}],"container-title":["Skin Appendage Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000543221","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000543221","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,4]],"date-time":"2025-06-04T16:03:38Z","timestamp":1749053018000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000543221"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12,19]]},"references-count":15,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2025,6,4]]},"published-print":{"date-parts":[[2025,6,4]]}},"URL":"https:\/\/doi.org\/10.1159\/000543221","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.28044914","asserted-by":"subject"}]},"ISSN":["2296-9195","2296-9160"],"issn-type":[{"value":"2296-9195","type":"print"},{"value":"2296-9160","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,12,19]]}}}
