Hair loss after COVID-19 isn’t brought by the virus affecting hair follicles, doctors say. But, they think it’s most likely caused by a reaction to the physiological or emotional stress caused by the disease.

This kind of covid hair loss is possible, which the experts term as telogen effluvium, is related to psychological stress and physical stress.

Coronavirus can cause many factors that can precipitate hair loss, such as psychological stressors like prolonged fear and the death of a family member.

The effect is that the hair loss itself often causes more stress, leading to more hair loss. Also, hair loss can be a widespread side effect of drugs that are used to treat COVID-19. Read on to know the causes of hair loss.

1 Fever

People who are infected with COVID never show symptoms. But, other asymptomatic COVID patients may have a fever.

We know people having high fever do not have a synchronized shedding phase, or telogen effluvium, for about six weeks when the fever has begun. This hair loss can last many weeks before normalizing.

2. Stress and anxiety

Stress has a significant number of effects on some organ systems in the body, like the digestive tract, brain, and hair follicles. Abnormal cortisol levels may also damage hair follicle functioning.

Although stress is not a significant cause of covid hair loss, we also have some underlying conditions triggered by stress. So, stress is not the primary cause, but it acts as an effect.

A lot of people are reporting hair loss during COVID because it’s a stressful period. And also, those whose bodies are affected by stress in a more chronic response don’t produce the stress hormone cortisol. When the immediate threat has passed, then you will start experiencing hair loss.

 3. Nutritional disruption

Loss of appetite, nausea, vomiting, together with diarrhoea are the known symptoms of COVID. All these conditions may also lead to hair loss.

The body expends a big deal of energy developing hair, which affects nutrition because of quality or quantity of intake and anything concerning malabsorption. Disruption of the gut microbiome can have an effect on the significant metabolic population of hair follicles on the scalp. 

 A single gram of hair about the quantity of hair you can fit into a standard sugar packet needs nearly 650kJ of energy to produce. This is about the power required for around 15 minutes of continuous cardio exercise.”

4. Sleep disruption

Stress from income loss, job insecurity and isolation can be affecting your sleep. All this is the damage of hair as well.

A new find suggests the complex local control of the hair follicle cycling, which the brain’s natural circadian rhythm can influence.

This can show why night-shift workers, severely and those with significant sleep disruptions or staying asleep, can experience chronic hair loss together with other hair loss symptoms.

5. Changes in blood flow

COVID-19 has been affecting blood clotting and blood flow in the body. Blood flow to the scalp is essential for scalp and hair health also.

Because of the restrictions in blood flow and clotting effects related to COVID-19, there can be a mechanism of slow down blood flow to the hair follicles. And it can starve out other robust hairs, causing a big hair shed in anagen effluvium type scenario.

When the clotting is reduced, blood flow can go back to relatively as usual, and hair can start growing back. But also reason may be starvation of the hair follicles through the reduction in nutrition in the blood flowing to the hair.

Because the clotting factors with various respiratory issues. The demand and availability of particular vital nutrients like serum iron and ferritin can drastically be altered while the virus is in total active.

Because of this, it’s also possible that a decrease in the supply of iron to the hair during the active virus can result in rapid hair loss. Knowing that the individual can return to a normal state soon, he may experience a full recovery.

6. Compliance

As each of us has been staying at home more, many of our routines have reduced to the other side. People are lacking daily routine check-ups with doctor’s appointments, and they may be reducing their treatments and regimes.

Abilities for many have changed as quickly as lockdown orders, working from home, and learning from home came about. These changes have resulted in a lot of hair loss patients finding their hair reduction.


When you’re experiencing covid hair loss, the first advice to patients is not to stress. When it’s telogen effluvium, your hair will start getting back on its own.

Make an appointment to see a physician when the issue lasts more than six months. It would help if you also visited a doctor when the hair loss is associated with a rash, flaking or itching, that can show a different problem.
