Effect of COVID-۱۹ Vaccines on Hair Loss

Aims: The COVID-۱۹ pandemic has led to the global distribution of vaccines, but there are concerns regarding potential side effects. Hair loss is one of the less commonly reported side effects. The present study aimed to investigate the effect of COVID-۱۹ vaccinations on hair loss. Instruments & Methods: A cross-sectional descriptive study was conducted with ۵۸۰ participants aged between ۲۰ to ۷۲ years, consisting of ۲۷۰ males and ۳۱۰ females. Machine learning techniques were employed to analyze the data and determine any potential relationship between COVID-۱۹ vaccines and hair loss. A logistic regression analysis was used to assess the odds ratio and ۹۵% confidence interval for hair loss. Findings: Of the total participants, ۱۷.۶% reported experiencing hair loss after receiving the COVID-۱۹ vaccine. This percentage was higher in females (۱۹.۴%) compared to the males (۱۵.۲%). There was a significant association between the COVID-۱۹ vaccine and hair loss in both males and females. The odds ratio for developing hair loss after receiving the COVID-۱۹ vaccine was ۱.۳۴ (۹۵% CI: ۱.۰۴-۱.۷۳) for females and ۱.۱۲ (۹۵% CI: ۰.۸۱-۱.۵۴) for males. Conclusion: Hair loss is a rare but possible side effect of COVID-۱۹ vaccination in both males and females, which its prevalence is higher in females than in males. Individuals with certain comorbidities, such as hypertension and diabetes, may be at a higher risk for experiencing hair loss after COVID-۱۹ vaccination.
