Reversal of Stress-Associated Alopecia
Abstract:
Novel coronavirus SARS-CoV-2, designated as COVID-19 by the World Health Organization (WHO) on February 11, 2020, is one of the highly pathogenic β-coronaviruses that infects humans.1 Alopecia areata (AA) is a chronic inflammatory disease with sudden hair loss.2,3 There is strong evidence that AA is a tissue-specific autoimmune disease that develops based on genetic predisposition.4 In several patients, acute or chronic psycho-emotional stress may be causing the initiation and/or progress of AA.5 It is suggested that psychological stress can trigger or exacerbate inflammatory skin diseases through the neuroendocrine system, which is an essential connection between the brain and the skin.6,7 Hair loss has emerged as a frequently noted side effect of infection with COVID-19, and has been observed in many patients who have recovered from a documented COVID-19 illness.8,9.
