Decoding Hair Loss after COVID

Understanding the Causes, Duration, and Solutions for Hair Shedding After Illness or Fever

Weeks or months after having a fever or COVID, some patients are noticing their hair falling out in clumps. This is actually called “hair shedding”. Patients should know that sickness and fevers can cause your hair to shed during the hair growth lifecycle.


What is hair shedding and how long does it last?

Two or more months after fever or illness, handfuls of hair can come out when you brush your hair or shower. This “shedding” process can last on average six to nine months. Extreme stress can contribute to hair shedding. During the pandemic and illness, many experience additional stress that leads to hair loss.

Is Hair Shedding after COVID-19 Normal?

Hair shedding after COVID-19 is a common phenomenon, typically occurring two or more months after a fever or illness. This shedding is a natural response during the hair growth cycle.

How Long Will Hair Shedding Last?

Hair shedding can last for an average of six to nine months. While it might be alarming to see handfuls of hair during brushing or showering, it's often a temporary phase linked to the stress of illness.

Do My Genetics Play a Role?

While most cases of hair shedding resolve with time, it can sometimes unmask underlying genetic hair loss (androgenic alopecia). If shedding persists beyond 6-9 months, it's advisable to consult with a dermatology provider for a comprehensive evaluation and potential solutions.
"Most who experience hair shedding will see the hair returns to normal with time," says Sarah Lund Peterson, PA-C.

What should I do about hair shedding?

Genetics play a key role in hair loss as well, and hair shedding can sometimes unmask an underlying androgenic, or genetic hair loss. If hair does not return to normal 6-9 months after experiencing hair shedding, this may be the case. Though there is no cure for androgenic alopecia, PRP treatments use your own growth factors extracted from your blood to stimulate thicker healthier hair growth and can combat the signs of genetic hair loss. 

If you feel you are experiencing hair loss for reasons other than illness or COVID, please call your dermatology provider for an appointment.
