A Case of Acquired Trichorrhexis Nodosa After Applying New Hair Spray

A 17-year-old boy developed acquired localized trichorrhexis nodosa, characterized by whitish nodes on the hair shaft, after changing his hair spray during the summer. The condition, which appeared in the temporal zones bilaterally, was diagnosed through microscopic examination. The patient had no relevant medical history or family history of similar conditions. The study suggested that the combination of the new hair spray, sun exposure, and hair styling might have contributed to the hair damage, though the exact cause remained unclear. The condition was managed by cutting the affected hair to achieve a cosmetically acceptable result.
