Rejuvenation of the Male Scalp Using 1,927 nm Non-Ablative Fractional Thulium Fiber Laser

The document describes a study where four male patients with Fitzpatrick skin types II-III received a single treatment with a 1,927 nm non-ablative fractional thulium fiber laser to address extensive photodamage on the scalp. The treatment resulted in a 60-90% improvement in dyspigmentation, lentigines, and keratoses, with no adverse events reported and good patient tolerance. The follow-up period was 2 weeks, and the study is the first to document successful scalp rejuvenation with this laser type. However, the study had limitations, including a short follow-up time and the absence of a control group. The authors suggest a maintenance regimen every 6-12 months and call for further research to support these preliminary findings.
