Clinical Evaluation of Localized Scalp Thread Embedding for Male Androgenetic Alopecia

Volunteers who met the inclusion criteria were enrolled in the trial. All participants underwent treatment intervention in the vertex alopecic area via vertex alopecic area scalp thread embedding. A single thread embedding session was performed upon enrollment, with monthly follow-ups conducted over a total period of 6 months. Operative procedure: After fully exposing and disinfecting the treatment area, threads were inserted into the scalp at an approximately 15-degree oblique angle, with needle tips reaching the subgaleal space at a depth of 2-4 mm. Threads were spaced 1 cm apart. Upon completion, the treated area was disinfected and applied with erythromycin ointment.
