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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We performed a retrospective case series of 13 patients diagnosed with TE at a Dermatologic Laser Center in Mexico.

No adverse events occurred.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>675-nm diode laser seems to be a safe, well-tolerated, and potentially effective adjuvant therapy for TE.
