COVID-19 and Hair Loss:

Hair loss has emerged as a surprising yet significant aftereffect of COVID-19, with many individuals experiencing excessive shedding in the months following infection. This condition, known as telogen effluvium, occurs when a physical or emotional stressor, such as a severe illness, pushes a large number of hair follicles into the resting phase, leading to noticeable thinning. The sudden shock of the virus on the body, combined with factors like fever, inflammation, and emotional distress, can trigger this temporary but distressing form of hair loss.

Research indicates that post-COVID hair loss generally begins two to three months after infection and can last for several months before gradually resolving. A study published in The Lancet found that a significant percentage of recovered COVID-19 patients reported hair shedding as a lingering symptom. Another study in JAMA Dermatology confirmed that COVID-19-related telogen effluvium follows a similar pattern to hair loss caused by other febrile illnesses but may be more severe due to the prolonged inflammatory response associated with the virus.

Fortunately, post-COVID hair loss is usually temporary, with regrowth occurring naturally over time. Dermatologists recommend a balanced diet rich in essential nutrients, stress management techniques, and proper scalp care to support recovery. In some cases, treatments such as minoxidil may be prescribed to encourage faster regrowth. While the experience can be alarming, understanding the temporary nature of COVID-related hair loss can provide reassurance to those affected.
