Effect of Microneedling with Growth Factors and Low-Level Light Therapy on Trichotillomania Treatment

Abstract

Trichotillomania (TTM) is a compulsive disorder causing hair loss and emotional distress. While behavioral therapies are common, dermatological treatments are less explored. This study examines a novel combination therapy of microneedling with growth factors and low-level light therapy (LLLT). To evaluate the efficacy and safety of combined microneedling and LLLT as an adjunctive therapy in promoting hair regrowth in TTM. A 26-year-old female underwent 0.2 mm microneedling with growth factors and LLLT twice weekly for four months. Outcomes were assessed through hair regrowth observation and safety evaluation. The patient achieved visible hair regrowth without side effects after eight sessions over four months. Scalp condition improved, and treatment was well-tolerated. This combined therapy is effective and safe for TTM-related hair loss, offering potential as an adjunctive treatment. Further research with larger cohorts is recommended.
