In recent months, images of people who say they have begun to have small bald spots on their scalp have appeared in certain Telegram groups after having received the vaccine. COVID-19.

Specifically, it ensures that “He had received the first injection of Moderna on April 8, 2021, and then his hair began to fall out.” What could it have been? Has the vaccine had anything to do with it?

What does the evidence say?

Although some researchers have found cases of alopecia areata (or bald spots), In addition, it is not listed as a side effect of the vaccine.

Yes, there is more international scientific consensus in stating that cases of hair loss occur within a few months of. In any case, they are usually cases of telogen effluvium and, therefore, it is a temporary phenomenon.

What is known about the cases of hair loss after the vaccine and the spread of COVID-19?

Among the side effects of Moderna’s vaccine, there also does not appear to be scientific evidence that it is occurring: “Although hair loss is a recognized adverse effect of different medications, it is not believed to be associated with routine or routine vaccination”, points out to Verificat Shoshana Marmon, dermatologist, assistant professor and director of clinical research in the department of Dermatology at New York Medical College (USA). “We really haven’t had new appearance associated with vaccination ”, he adds.

In the absence of scientific publications on hair loss in vaccinated patients, five researchers from Egypt sent a letter to the Journal of Cosmetic Dermatology describing the case of a patient who had alopecia areata, a form of non-scarring alopecia of autoimmune origin. ,

In their conclusions, the researchers insist that, although said injection is safe and effective against symptomatic COVID-19, “Our report suggests its possible role in the activation of alopecia areata (which is colloquially known as ‘bald spots’) in genetically predisposed patients through immune-mediated mechanisms.”

Marmon agrees with them, who insists on having had “Numerous cases of hair loss as a result of COVID-19 infection and we continue to see these patients regularly in the clinic.”

The most common type of hair loss that experts have detected is telogen effluvium, an alteration of the hair growth cycle that occurs when more hairs than normal enter the shedding (telogen) phase of the hair growth life cycle. . “Fever, illness and severe stress are some of the triggers that can force hair to fall into the fall phase”, Sharnon lists, although he sends a reassuring message: “Despite being definitely somewhat disturbing, hair loss caused by TE is temporary and

The effect is quite common in general, and not only occurs with COVID-19 positives: “Most people see noticeable hair loss two to three months after having a fever or illness”, they point out from the AAD. “This hair loss can last six to nine months before it stops,” they conclude.
