Experiencing Hair Loss after Vaccination

Hair loss can be due to many reasons. Some of them include certain medications, high fevers, hormonal changes, pregnancy, surgical shock, transplant surgery, poor diet (lacking in essential fatty acid, biotin, zinc, iron deficiency), anemia, aging, male pattern baldness, thyroid disease causing decreased thyroid levels (hypothyroidism), severe emotional stress, and autoimmune disease (disease that affects the body's ability to recognize its own tissues, causing it to gradually destroy them). Then again, recent research shows that hair loss could occur in some people who have taken vaccinations. If confirmed by other studies, the side-effects could be considered very rare.

For quite some time now, reports of hair loss were identified and evaluated among individuals who had taken vaccines. These hair loss cases were hundreds out of the millions of doses of vaccines that were taken by the overall population. Then again, just this study can’t prove that vaccines cause hair loss. Other health conditions that could not be identified could also be responsible for the hair loss.

While all vaccines of hair loss, in this study, were investigated with reports, the hepatitis B vaccine seemed to suggest more association with these rare cases of hair loss, than other vaccines. It was also found that some patients had lost hair again when they received additional doses (the recommended 3 doses) of the hepatitis B vaccine.

The study also revealed fewer men than women reporting hair loss. However, there could be other reasons for this. Some of them would include:

  1. Men may not report hair loss quite as often as women since their hair is usually worn shorter and hair loss may not be as noticed as much as in women with longer hair. Further, quite a few men expect to lose their hair as they age (e.g. male pattern baldness).
  2. Women and health care workers who testified to hair loss were more in touch with their health care providers about health concerns.

The good news is that, in more than half of the cases, hair did grow back, but in a few cases only partial regrowth of hair was reported. Acute hair loss on more than half of the head or body was reported in many of the cases that were assessed. Of the reports of acute hair loss, some people recovered most or all of their hair, while a few reported consistent baldness.
