Abstract: Background: Telogen effluvium (TE) is a diffuse, non-scarring alopecia that can have a significant impact on quality of life. Although often self-limited, many patients seek therapies that speed recovery. Photobiomodulatory benefits of the 675-nm diode laser are also well established in treating other hair disorders, but there is limited evidence in TE. Methods: We performed a retrospective case series of 13 patients diagnosed with TE at a Dermatologic Laser Center in Mexico. The patients received adjuvant treatment with 675-nm diode laser therapy. Results: Of the 13 patients, 69% had chronic TE. Among those with a positive baseline pull test, 72% became negative at follow-up. Pruritus improved in 83% of symptomatic patients, and trichodynia resolved in 75%. No adverse events occurred. Conclusion: 675-nm diode laser seems to be a safe, well-tolerated, and potentially effective adjuvant therapy for TE. Controlled studies are needed to confirm efficacy and establish standardized protocols.
