ABSTRACT
Introduction: Telogen effluvium (TE) is characterized by diffuse hair shedding 2-3 months after a stressor, and factors such as hypoxia, inflammation (interleukin 6), medications and need for mechanical ventilation may play a role in the development and severity of TE caused by COVID-19. Aims: Evaluate the benefit of the hair care routine using products containing active ingredients to reduce the microinflammation of the scalp and increase the resistance of the hair strand to treat subjects with TE caused by COVID-19. Case presentation: After 60 days of the hospitalization due to COVID-19 infection, a 58-year-old woman showed a typical diagnostic of TE associated to post–COVID-19 infection, presenting positive results to traction test, trichoscopy, and trichogram. During 30 days, she used: 1) Product A: shampoo containing Aminexil, niacinamide, pyridoxine and panthenol;2) Product B: conditionate containing SP94 (glucose + linoleic acid);and 3) Product C: treatment ampoules containing creatine, panthenol, and ceramide R. The products A plus B were used once time for daily and the product C was used 3 times a week. Results: After the treatment, the subject presented an improvement of 100% of the hair loss, with negative results to traction test, trichoscopy, and trichogram analysis. The subject reported a high satisfaction with the treatment (ratio 10/10). Discussion: The hair care routine using the products A, B, and C could improve the TE caused by COVID-19, maybe by reduction inflammatory process in the scalp. Clinical studies in the high scale must be conducted to proof this hypothesis.
