Large study shows that COVID-19 is linked to hair loss

Since the rates for COVID-19 vaccinations remain stubbornly low, I do my best to point out reasons for getting the vaccine. Next up, new research shows that COVID-19 infections are linked to hair loss. That’s right, getting COVID-19 can increase your chances of going bald.

As I usually do, I will examine the data from the research and critique the study to determine if it is, indeed, a reason to avoid COVID-19 by getting vaccinated.

COVID-19 and hair loss paper

In a paper published on 10 January 2024 in JAMA Dermatology, Jin Park, MD, PhD, of Jeonbuk National University Medical School in Jeonju, South Korea, and colleagues performed a cohort study that included 259,369 patients with COVID and 259,369 patients without COVID. Patients were matched by demographic characteristics and comorbidities.

The researchers examined the incidence of alopecia areata, a type of hair loss that forms in patches and is potentially caused by an autoimmune disorder, in COVID and non-COVID cohorts. The incidence of autoimmune diseases appears to be higher in individuals who have had COVID-19 compared to those who haven’t (and another reason to avoid the disease with vaccines).

Here are the key results from their research:

  • Generally, the researchers found that hair loss from alopecia areata significantly increased after COVID-19, a nationwide study involving more than half a million South Koreans found.
  • The incidence of this autoimmune form of hair loss was 82% higher for individuals with versus those without a prior COVID infection.
  • The study also revealed a 6.4X increase in the incidence of telogen effluvium, that is, rapid hair loss triggered by stress or other changes to the body, among the cohort with COVID-19 compared with the control group.

The researchers speculated that COVID-19 induces a cytokine storm that leads to an autoimmune disorder like alopecia areata.


COVID-19 is linked to many conditions from diabetes to death, but people still don’t seem concerned and make every excuse to avoid the vaccines that can prevent COVID-19. This study shows that contracting COVID-19 can lead to a particular type of hair loss and pattern baldness that is not reversible. You can lose your hair and never bring it back.

If I can’t appeal to anything but vanity in preventing COVID-19, then I present this study.
