Can Covid-19 trigger hair loss? Here’s what you’ll want to know.

In the months following a Covid-19 an infection, many individuals have reported elevated hair loss—a phenomenon consultants say is comparatively widespread, and sure short-term, Knvul Sheikh writes for the New York Times.

How widespread is hair loss after Covid-19?

Research estimates that 22% of sufferers hospitalized with Covid-19 expertise sudden and short-term hair loss—often called telogen effluvium—following an an infection. 

While it’s tougher to find out how widespread hair loss is in individuals who skilled delicate types of Covid-19, studies counsel that it’s one in every of over 60 persistent signs usually related to lengthy Covid.

Throughout the Covid-19 pandemic, many docs have noticed a rise in sufferers searching for assist for the situation. “I have never seen anything like it in my life,” mentioned Michele Green, a New York City-based dermatologist who’s affiliated with Northwell Health‘s Lenox Hill Hospital and focuses on hair loss. “I’m seeing more male and female patients, from every age group, every working profession. It’s really been across the board.”

What causes elevated hair loss after Covid-19?

According to Sheikh, telogen effluvium “occurs when stress or illness triggers much more shedding than the typical 50 to 100 hairs a person loses per day.”

Notably, the situation isn’t particular to Covid-19. “Experts have known for centuries that severe illness, surgery, blood loss, hospitalization, childbirth and extreme emotional events, like the loss of a loved, one can trigger telogen effluvium,” Sheikh writes.

However, evidence means that individuals who have a historical past of Covid-19 an infection are 4 occasions as seemingly to expertise hair loss than those that haven’t any historical past of an infection.

While consultants don’t totally perceive how bodily and emotional stressors trigger telogen effluvium, many dermatologists believe a stress hormone referred to as cortisol might play an element.

However, Luis Garza, a professor of dermatology on the Johns Hopkins University School of Medicine, famous that different chemical substances might present a sign telling hair follicles when to shed.

For many, “Covid-19 has been a double whammy,” combining “the mental stress of living through a pandemic” with “the physical stress of the illness itself,” Sheikh writes.

Typically, particular person hairs cycle by way of three phases—the anagen section, catagen section, and telogen section—earlier than falling out. The follicle then repeats your complete course of. Each strand goes by way of totally different phases of the cycle at totally different occasions, which means that solely 5% to 10% of an individual’s hair on their head ought to be within the telogen section at any cut-off date.

“Telogen effluvium short-circuits the cycle for many hairs,” Garza mentioned. When this occurs, 30% to 50% of an individual’s hair enters the telogen section, which ends up in giant quantities of hair falling out two to a few months after an sickness.

Fortunately, the hair loss is normally short-term. Experts have famous that whereas it might final between six and 9 months, the shedding ultimately slows, and new hair begins to develop.

What do you have to do in case you are experiencing hair loss after Covid-19?

According to Sheikh, it is best to see a health care provider for those who discover sudden hair loss or are involved concerning the quantity of hair you might be shedding. “By intervening early, particularly if your hair loss is linked to an underlying condition, you can treat it effectively,” Sheikh writes.

“Usually you’ll know if you’re losing hair long before anyone can actually clinically see it,” Green mentioned.

Typically, docs document your medical historical past, order blood work, and carry out a hair-pull take a look at, which entails gently pulling small sections of hair from totally different areas of a affected person’s scalp. “If six or more strands fall out without resistance, it is a positive indicator of active loss,” Sheikh writes. “In some cases, your doctor may also order a biopsy to examine your hair follicles.”

If a affected person has telogen effluvium, most docs will counsel ready for the hair to develop again by itself.

“A lot of what I do is counsel people when it occurs and play the role of a cheerleader for them, reassuring them that this will get better,” mentioned Arash Mostaghimi, director of dermatology inpatient service at Brigham and Women’s Hospital.

However, some dermatologists might suggest a topical resolution of minoxidil—the hair-growth drug that’s the lively ingredient in Rogaine.

According to Garza, stress administration can usually be an efficient technique to handle the situation. “One thing I tell patients who come in for hair loss is that they might benefit from seeing a therapist, because we know that stress causes hair loss and hair loss also adds to stress,” he mentioned. “Hair is a huge component of our identity.”

While some folks flip to dietary supplements that aren’t well-regulated to spice up their hair development, Mostaghimi famous that most individuals’s diets already embrace sufficient of the nutritional vitamins and minerals wanted for good hair development. “I discourage people from being too aggressive in trying these because you may end up spending a lot of money on these items when the benefits are marginal if any,” Mostaghimi mentioned.

Ultimately, consultants emphasize that telogen effluvium following Covid-19 isn’t normally everlasting.

“The majority of my patients who came to me in the beginning of the pandemic are already doing better,” Mostaghimi mentioned. “Their hair has recovered and they are able to express themselves with their hair the way that they want.” (Sheikh, New York Times, 9/30)
