Although it is self-limiting, hair loss can be very distressing, and some patients may seek medical treatment to help promote hair regrowth. Low-dose oral minoxidil (LDOM) has emerged as a novel and very efficient therapy for different types of alopecia. However, information on its safety and efficacy profile in the management of CATE remains scarce. This study aims to evaluate the treatment response to LDOM in CATE patients.</div></div><div><h3>Methods</h3><div>We conducted a retrospective study at a single dermatology center. Adult patients diagnosed with telogen effluvium from December 2020 to October 2022, with a prior history of SARS-CoV-2 infection, and treated with LDOM were included. The efficacy of LDOM was evaluated with the hair-shedding score (HSS).</div></div><div><h3>Results</h3><div>In all, 69 patients, 50 (72.5%) women and 19 (27.5%) men were included.

The time elapsed between COVID-19 and telogen effluvium diagnosis was 117 days (80–181). The HSS continuously decreased during the 2nd, 3rd, and 4th visits after treatment initiation.
