Latest Findings Link Covid to Increased Risk of Alopecia Areata

While the pandemic caused all kinds of challenges, some of its unexpected side effects, like hair thinning and shedding, are only just coming to light.

Recent research has uncovered a possible connection between COVID-19 and an increased risk of alopecia areata, prompting new discussions about how viruses, stress, and our immune systems all play a role in hair health.

Here, we’ll explore the findings, discuss other forms of COVID-related hair loss, and share what you can do if you’re experiencing unusual shedding.

Study links COVID-19 to alopecia areata

A recent study carried out in South Korea, has found that COVID-19 may be associated with a higher risk of developing alopecia areata. This common condition occurs when the body’s immune system attacks its own hair follicles, leading to patchy hair loss.

While alopecia areata can happen to anyone, this research suggests that a COVID-19 infection could potentially heighten the chances of it occurring. Researchers also noted an increased risk for other immune-related skin conditions like vitiligo and chronic urticaria.

These findings support a growing consensus that COVID-19 doesn’t merely affect the respiratory system; it may also trigger complex immune responses in the body. When this happens, hair follicles can become collateral damage as part of an overactive immune response.

Understanding temporary shedding due to illness

Several people recovering from COVID-19 report increased hair shedding, often referred to as telogen effluvium. This form of hair loss commonly follows periods of major physical or emotional stress, such as high fevers, surgeries, or, indeed, severe viral infections.

In the case of COVID-19, the stress load on the body, combined with the emotional toll of the illness, can push more hair follicles than usual into the resting (telogen) phase. After a few months, these resting hairs fall out in greater quantities, causing noticeable shedding.

The good news is that telogen effluvium is typically temporary. Once the body recovers and stress levels decrease, most people find their hair growth cycle returns to normal, and lost strands eventually regrow over time.

However, it’s important to differentiate between patchy hair loss (which could suggest alopecia areata) and general shedding (often tied to telogen effluvium). Understanding which form of hair loss that you are experiencing can help you identify the most effective interventions.

Management and prevention

If you or someone you know has noticed hair thinning or bald spots following COVID-19, it’s understandable to feel concerned. The first step is to consult a professional for a proper diagnosis, especially if you’re seeing patchy, circular areas of loss, which could point to alopecia areata.

Determining the cause is crucial because the right treatment varies depending on the diagnosis. For alopecia areata, some therapies focus on calming the immune system, while telogen effluvium often requires nothing more than time, good nutrition, and stress management for hair to bounce back.

Lifestyle adjustments can also support healthier hair regrowth. This includes following a balanced diet rich in protein, vitamins, and minerals, as well as maintaining an exercise routine to help manage stress.

Scalp-friendly habits like gentle hair care, limiting heat styling, and avoiding harsh chemical treatments, can further minimise breakage.

If you’re concerned about post-COVID hair loss, don’t wait until the shedding becomes overwhelming. Reach out for professional advice and explore personalised options.

Whether it’s alopecia areata or temporary hair thinning, understanding the root cause is half the battle.
