What causes hair shedding after the flu?

Question

Hello doctor,

I am writing to discuss a concern that has been causing me some distress. Approximately a month ago, I experienced a severe bout of the flu. Since then, I have observed a noticeable increase in hair shedding. At 35 years old, I have not encountered such an issue before, and it is becoming a source of anxiety for me. I would like to understand:

Is it common to experience hair loss following an illness like the flu?
What is the typical duration for such hair shedding to subside?
Are there recommended treatments or practices to promote hair regrowth and prevent further loss?

I maintain a balanced diet and take regular vitamin supplements, but I am concerned about the potential for full recovery. Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Based on your description, it sounds like you might be experiencing telogen effluvium, a common and temporary form of hair shedding that often occurs a few weeks to months after a significant physical or emotional stressor, such as a severe flu. During this condition, more hair than usual shifts from the growing phase (anagen) into the resting phase (telogen), leading to increased shedding. This typically becomes noticeable four to eight weeks after the triggering event and can last for about three to six months, though full recovery may take up to nine to 12 months in some cases.

The encouraging news is that telogen effluvium is usually self-limiting, and hair often regrows on its own once the body has fully recovered. To support regrowth:

Maintain a balanced diet: Ensure your meals are rich in protein, iron, zinc, and B-vitamins (especially biotin). Foods like lean meats, leafy greens, nuts, and whole grains can be beneficial.
Continue with your multivitamins: If they contain these key nutrients, they can aid in hair health.
Be gentle with your hair: Avoid tight hairstyles, heat styling, or harsh chemical treatments, as they can exacerbate hair loss.
Consider topical treatments: If shedding persists beyond six months, over-the-counter options like Minoxidil may help promote hair growth. However, it is essential to discuss this with your doctor before starting any new treatment.
Check your iron and thyroid levels: Persistent hair loss can sometimes be linked to deficiencies or thyroid dysfunction. Consulting with a healthcare provider can help identify and address any underlying issues.

Lastly, it is important to manage stress, as anxiety about hair loss can further impact the hair growth cycle. Engaging in relaxation techniques, regular exercise, or speaking with a counselor can be beneficial. If you do not notice improvement within a few months or if you observe bald patches or changes in your scalp, it is advisable to consult a dermatologist for further evaluation.

I hope this helps.
