Platelet-Rich Plasma Treatment for Accelerated Androgenetic Alopecia Pattern Hair Loss After COVID-19 Infection: A Case Series.

BACKGROUND: Hair-related manifestations such as alopecia areata or telogen effluvium were reported during COVID-19 disease. Accelerated hair loss with androgenetic alopecia (AGA) pattern or management has not been discussed before. AIMS: This study aimed to examine the accelerated AGA pattern hair loss and management with PRP treatment. MATERIALS AND METHODS: This study was designed prospectively and nine patients included to study confirmed PCR test for COVID-19 infection. Patients underwent platelet-rich plasma (PRP) injections for 4 sessions. Results were accessed with the hair pull test (HPT) and self-administered hair growth questionnaire (HGQ). RESULTS: Nine patients were admitted with complaints of hair loss after an average of 220 ± 24.2 (min: 182 max: 264) day after recovery of COVID-19. Mean age of the patients was 33.8 ±8.4 years old (min: 26, max: 52). Six (66.7%) patients were male, and three (33.3%) of them were female. HPT score decreased to 6.0 ± 1.6 after the first PRP application (p = 0.007, CI 95%:2.7-5.2) and decreased to 1.2 ± 0.8 after the last PRP session (p = 0.008, CI 95%: 6.4-11.1). Five (55.5%) of the patients described the treatment as "very effective" after treatment with HGQ. CONCLUSIONS: Accelerated hair loss associated with COVID-19 continues in long term and PRP treatment provides a satisfactory solution.
