There is no evidence that COVID-19 vaccines cause hair loss
To know the adverse reactions of these vaccines, just look at their technical sheets. None of them mention hair loss.. Here you can consult the Comirnaty (Pfizer/BioNTech), Spikevax (Modern), Vaxzevria (AstraZeneca), Jcovden (Janssen), Nuvaxovid (Novavax), Valneva y VidPrevyun Beta (Sanofi).
Some case studies they point out a possible relationship between the COVID-19 vaccine and alopecia areata (a condition that causes round patches of hair loss and can lead to complete baldness).
However, The authors themselves highlight that cases of this type of alopecia are rare. and? it is not clear that they are caused by the vaccine. This is what happens, for example, with a study published in February 2022 in the journal JAAD Case Reportswhich documents 9 cases of alopecia areata after vaccination, between December 2020 and October 2021.
The authors insist that cause and effect cannot be clearly identified in either case. That is, just because a patient suffers from this type of alopecia after being vaccinated does not mean that the condition was caused by the vaccine.
Furthermore, it is a case study, a scientific work that studies a very particular event and whose conclusions usually cannot be extrapolated to the general public, as explained in this note Maldita.eshalf co-founder of Factchecked.
Mental stress caused by the pandemic may have contributed to some of the reported cases, according to an article published in the journal Aesthetic Surgery Journal. “Stress is a trigger for alopecia areata”, state the authors. Although they do not rule out that there may be a link between vaccines and this condition, they highlight that more research is needed to know for sure.
As several point out studies y health authoritiesvaccines against COVID-19 They are safe and effective and reduce the risk of serious illness, hospitalization and death from this disease.
Temporary hair loss is normal after having a fever or illness
Some users also ask on networks If hair loss can be a symptom of COVID-19. “Months after recovering from COVID-19, many people find that their hair falls out in large clumps” states the American Academy of Dermatology.
Fever is a common symptom of COVID-19, and as the AAD notes, temporary hair loss is normal after a fever or illness. This is what is called telogen effluvium, an alteration in the hair growth cycle that produces very noticeable hair loss. for a time-limited and reversible period of time.
The AAD notes that most people experience noticeable hair loss 2 to 3 months after having a fever or illness: “Handfuls of hair may come out when you shower or brush your hair.” This hair loss can last 6 to 9 months. Afterwards, your hair should look normal and stop falling out.
