While DF is a milder form characterized by mild scaling, itching, and no visible inflammation, SD presents as a more severe condition with red, scaly, and often inflamed lesions. Despite the high prevalence of these conditions, research specific to their epidemiology and management in Canada remains limited. This review examines the etiology, epidemiology, and management of DF and SD from a Canadian perspective. It highlights the role of\n                    <jats:italic toggle=\"yes\">Malassezia<\/jats:italic>\n                    species in the pathogenesis of both conditions and explores the influence of genetic, environmental, and microbial factors. The review also outlines the diverse clinical presentations of DF and SD across different ethnicities and the effectiveness of various over-the-counter and prescription treatments available. Additionally, the article emphasizes the lack of a Canadian consensus on the management of these conditions, calling for further research and formalized guidelines to better inform health care providers and improve patient care. Given the diverse Canadian population and the increasing burden of DF and SD, a more tailored approach to treatment is essential to address the challenges posed by these chronic conditions.\n                  <\/jats:p>","DOI":"10.1177\/12034754251368845","type":"journal-article","created":{"date-parts":[[2025,10,24]],"date-time":"2025-10-24T12:15:46Z","timestamp":1761308146000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Understanding the Scalp: Dandruff and Seborrheic Dermatitis"],"prefix":"10.1177","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8664-7723","authenticated-orcid":false,"given":"Aditya K.","family":"Gupta","sequence":"first","affiliation":[{"name":"Mediprobe Research Inc., London, ON, Canada"},{"name":"Division of Dermatology, Department of Medicine, Temerty Faculty of Medicine, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian","family":"Landells","sequence":"additional","affiliation":[{"name":"Landells Clinic, Nexus Clinical Research, St. John\u2019s, NL, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mesbah","family":"Talukder","sequence":"additional","affiliation":[{"name":"Mediprobe Research, London, Ontario, Canada &amp; School of Pharmacy, BRAC University, Dhaka, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eunice","family":"Chow","sequence":"additional","affiliation":[{"name":"Division of Dermatology, Department of Medicine, Faculty of Medicine and Dentistry, University of Alberta, Edmonton, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renita","family":"Ahluwalia","sequence":"additional","affiliation":[{"name":"Canadian Dermatology Centre, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3091-640X","authenticated-orcid":false,"given":"Julio C.","family":"Jasso Olivares","sequence":"additional","affiliation":[{"name":"Division of Dermatology, CIUSSS du Montr\u00e9al H\u00f4pital Maisonneuve-Rosemont, Montreal, QC, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noemie","family":"Vezina","sequence":"additional","affiliation":[{"name":"Medical Director at Follicl MD, Hair restoration clinic, Montreal, QC, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9626-6863","authenticated-orcid":false,"given":"Geeta","family":"Yadav","sequence":"additional","affiliation":[{"name":"FACET Dermatology, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elias","family":"Raad","sequence":"additional","affiliation":[{"name":"L\u2019Or\u00e9al Canada, Montreal, QC, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4329-2029","authenticated-orcid":false,"given":"Nour R.","family":"Dayeh","sequence":"additional","affiliation":[{"name":"L\u2019Or\u00e9al Canada, Montreal, QC, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,10,24]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/exd.14091"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/jocd.14913"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000529854"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.13188\/2373-1044.1000019"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.2147\/CCID.S459498"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.4103\/0974-7753.82117"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0507.2008.01624.x"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.2147\/CCID.S284671"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2022.12.017"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/exd.14006"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1063\/5.0136543"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/myc.12276"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1080\/mmy.39.3.243.251"},{"issue":"3","key":"e_1_3_3_15_2","first-page":"185","article-title":"Diagnosis and treatment of seborrheic dermatitis","volume":"91","author":"Clark GW","year":"2015","unstructured":"Clark GW, Pope SM, Jaboori KA.
