June 2018 in “Clinical and Experimental Medicine” This study found that patients with alopecia areata had significant systemic inflammation and vitamin D deficiency, with both conditions more pronounced as disease severity increased.
191 citations
,
May 2018 in “British journal of dermatology/British journal of dermatology, Supplement” This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.
48 citations
,
April 2018 in “JEADV. Journal of the European Academy of Dermatology and Venereology/Journal of the European Academy of Dermatology and Venereology” This study found that individuals with alopecia areata had significantly lower serum vitamin D levels and a higher prevalence of vitamin D deficiency compared to people without the condition.
29 citations
,
December 2017 in “International Journal of Dermatology” This study found that vitamin D deficiency in patients with alopecia areata was associated with greater disease severity and longer duration, but not with disease pattern or vitamin D receptor expression.
99 citations
,
July 2017 in “Clinical Reviews in Allergy & Immunology” This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.
63 citations
,
May 2017 in “American Journal of Clinical Dermatology” This review found that patients with alopecia areata may have lower levels of vitamin D, zinc, and folate, but conflicting evidence precludes definitive clinical recommendations for micronutrient supplementation.
28 citations
,
April 2017 in “Journal of cosmetic dermatology” This study found that while vitamin D deficiency is not the sole cause of alopecia areata, it may worsen the disease, suggesting supplementation could help in pediatric cases.
20 citations
,
May 2016 in “Journal of Cosmetic Dermatology” This study suggests that lower serum and tissue vitamin D receptor levels in alopecia areata and androgenetic alopecia patients may play a role in the pathogenesis of these hair diseases.
52 citations
,
July 2015 in “International Journal of Dermatology” This study found that patients with alopecia areata had significantly lower serum zinc levels, which correlated inversely with disease severity, duration, and resistance to therapies, suggesting zinc assessment as a marker of disease status.
105 citations
,
March 2014 in “British journal of dermatology/British journal of dermatology, Supplement” In this study, patients with alopecia areata were found to have significantly lower serum vitamin D levels compared to those with vitiligo and healthy individuals, with lower levels correlating with increased disease severity.
13 citations

September 2007 in “International Journal of Dermatology” This study suggests no significant association between vitamin D receptor gene polymorphisms and alopecia areata.
