Many people who’ve recovered from COVID-19 are still dealing with long-term effects from the virus. We can now add noticeable hair loss to that list. Dermatologist Jeremiah Miller, MD, explained why.

“This type of hair loss, called telogen effluvium, happens not just after COVID-19, but it can occur after any stressful event – emotionally or physically – such as pregnancy, loss of a loved one, or significant weight loss. Hair loss is always alarming. The good news is that this is normally temporary,” said Dr. Miller.

How does stress cause hair loss?

Telogen effluvium is a process in which hair transitions from the active growing phase to the shedding phase all at once. The hair loss is usually noticeable a few months after an illness or major life event and then resolves on its own in 3 to 6 months.

Are there other causes of hair loss?

There are numerous types and causes of hair loss, such as thyroid disease, genetics and inflammatory conditions, making it important that your hair loss is evaluated and correctly diagnosed by a board-certified dermatologist. The most common type of hair loss is male and female pattern baldness, also called androgenic alopecia.

When should you see a doctor about hair loss?

Dr. Miller said it might be time to see a doctor if you are noticing rapid hair loss. Usually, a clinical exam is all that’s needed to make a diagnosis.
