The COVID-19 pandemic has left lasting effects on many people’s health, with hair loss being one of the most noticeable and distressing consequences for many. While the virus itself is primarily a respiratory illness, its impact on the body can extend to other systems, including hair growth. Hair loss after COVID has been widely reported. Here’s a breakdown of why it happens after COVID-19, its symptoms, and what can be done to manage it.

Hair Loss After COVID

Hair loss related to COVID-19 typically presents as telogen effluvium (TE), a temporary condition in which more hair than usual enters the shedding phase. This usually occurs 2–3 months after a physical or emotional stressor, such as illness, surgery, or severe infection. COVID-19, as a significant stressor, can trigger this response in the body. It’s important to note that this type of hair loss is generally not permanent, and hair usually grows back once the body recovers.

Why Does Hair Loss Occur After COVID-19?

Several factors contribute to the hair loss that follows a COVID-19 infection:

1. Physical Stress from Illness: The body’s immune response to an infection like COVID-19 can put it under significant stress. This stress can push hair follicles into the telogen (shedding) phase, leading to increased hair loss.
2. Fever: Fever, a common symptom of COVID-19, is another factor that can trigger telogen effluvium. When the body experiences a fever, it can disrupt the normal hair growth cycle, leading to hair shedding several weeks later.
3. Nutritional Deficiencies: During illness, many individuals experience a loss of appetite, difficulty eating, or digestive issues that affect nutrient absorption. A lack of essential nutrients, including iron, protein, and vitamins like vitamin D, can weaken hair and contribute to hair loss.
4. Psychological Stress: The psychological impact of dealing with a pandemic, anxiety about one’s health, and the emotional toll of isolation can also play a role in hair loss. Emotional stress has long been known to contribute to telogen effluvium, and it’s no different in the case of COVID-19.
5. Hormonal Changes: Stress from illness can alter hormone levels in the body, including cortisol, which can disrupt hair growth. Hormonal imbalances are a known cause of hair shedding, and they may exacerbate post-COVID hair loss.

How Long Does Hair Loss After COVID Last?

For most people, hair loss after COVID-19 is temporary and typically begins 2–3 months after the infection. The shedding process can last anywhere from 6 to 9 months before new hair starts to grow back. However, some individuals may notice the hair thinning persists for a longer period, though it often gradually resolves once the body fully recovers from the illness and stressors have diminished.

Managing Hair Loss After COVID-19

1. Focus on Nutrition: Eating a balanced diet rich in vitamins and minerals is essential for hair health. Nutrients like iron, biotin, vitamin D, zinc, and protein play a key role in hair growth. Consider incorporating more fruits, vegetables, lean proteins, and whole grains into your meals. If necessary, speak with a healthcare provider about supplements.
2. Practice Stress Management: Since stress can exacerbate hair loss, adopting stress-reduction techniques like meditation, yoga, deep breathing exercises, or regular physical activity can help manage both physical and emotional stress. Prioritize self-care and mental health to support your overall well-being.
3. Use Gentle Hair Care Practices: Avoid harsh hair treatments or tight hairstyles that can cause additional stress to your hair and scalp. Choose mild, nourishing shampoos, and use conditioners or leave-in treatments to help maintain moisture and prevent further damage.
4. Scalp Health: Maintaining a healthy scalp is vital for hair regrowth. Consider using scalp treatments that promote circulation and support follicle health. Oils like rosemary or peppermint oil have been shown to stimulate hair growth and improve scalp health.
5. Consult a Dermatologist or Trichologist: If you’re experiencing significant or persistent hair loss after COVID-19, it’s a good idea to consult with a dermatologist or trichologist. They can help determine the exact cause of your hair shedding and suggest appropriate treatments, such as topical solutions like minoxidil or prescription medications, if necessary.
6. Patience and Realistic Expectations: It’s important to remember that hair growth takes time. While it can be frustrating to experience hair thinning, especially after a challenging illness like COVID-19, it’s essential to be patient. Your hair will likely grow back, but it can take several months for visible results.

When Should You Seek Medical Attention?

While hair shedding after COVID-19 is typically temporary, there are cases where it may require medical intervention. If you notice:

• Severe or widespread hair loss
• Bald patches
• Itchy, painful, or inflamed scalp
• Continued hair loss beyond 9 months

It’s essential to consult a doctor to rule out underlying conditions such as alopecia areata or other health issues.

Frequently Asked Questions About Hair Loss After COVID

1. Why does hair loss happen after COVID-19?

Hair loss after COVID-19 is often caused by telogen effluvium, a condition where more hair follicles than usual enter the shedding phase due to physical or emotional stress. The body’s response to illness, fever, and the stress of the virus can lead to temporary hair shedding.

2. How long after COVID-19 can hair loss start?

Hair loss typically begins 2–3 months after the infection, as hair enters the telogen phase. You may start noticing shedding around this time, though it can last for several months before regrowth begins.

3. Is hair loss after COVID-19 permanent?

No, hair shedding caused by COVID-19 is generally temporary. Most people see regrowth after 6 to 9 months as the body recovers from the illness. However, in some cases, the process may take longer.

4. Can COVID-19 cause long-term hair loss?</h3>

In most cases, the hair loss is temporary. However, if the shedding continues beyond 9 months or worsens, it’s worth consulting a doctor to rule out other conditions or causes, such as underlying health issues.

5. How can I stop hair loss after COVID-19?

While you cannot entirely prevent post-COVID hair shedding, you can help manage it by focusing on a balanced diet, reducing stress, using gentle hair care practices, and keeping your scalp healthy. Nutrient-rich foods and stress management are key to promoting regrowth.

6. Will my hair grow back after COVID-related hair loss?</h3>

Yes, in most cases, your hair will grow back. Telogen effluvium is a temporary condition, and once your body recovers from the stress caused by the virus, hair regrowth typically resumes. It may take several months for noticeable results.

7. Can I use treatments to speed up hair regrowth?

While there’s no quick fix, treatments like minoxidil (Rogaine) or PRP (platelet-rich plasma) therapy may help stimulate hair growth. It’s best to consult a dermatologist to discuss the most effective treatments for your specific situation.

8. Is there any way to prevent hair loss after COVID-19?

While it’s difficult to prevent hair loss completely, you can reduce the severity by focusing on overall health. Eat a nutrient-dense diet, manage stress levels, and use gentle hair care products. Also, consider taking supplements like biotin or vitamin D if recommended by your doctor.

Conclusion

Hair loss following a COVID-19 infection is a common issue that many individuals face, but it’s important to know that it is typically temporary. Understanding the factors that contribute to post-COVID hair loss and taking steps to manage stress, nutrition, and hair care can help support your hair’s recovery. With time, most people experience regrowth, and the hair eventually returns to its normal thickness. Be patient, care for your hair, and remember that recovery is a gradual process.
