Red Nail Bands in Conjunction with Telogen Effluvium as a Post-COVID-19 Phenomenon

This multicenter study found that hair and nail disorders, particularly telogen effluvium, commonly developed in patients after severe COVID-19 infection.

COVID-19 may cause a temporary hair loss condition called telogen effluvium in some patients after recovery.

This retrospective study observed that telogen effluvium, a type of diffuse hair loss, frequently occurs in females aged 18–30 following SARS-CoV-2 infection, often accompanied by nutritional deficiencies, suggesting an association between COVID-19 and micronutrient deficiency, with acute cases being most common but chronic cases possible.

This study observed that post-COVID patients, especially females, commonly experience Telogen Effluvium, with earlier onset and increased trichodynia in those with more severe COVID-19.

This case study reports a 58-year-old woman experiencing pressure-induced alopecia with concomitant acute telogen effluvium after severe COVID-19, suggesting a potential link between prolonged hospitalization and hair loss.
