TLDR Radiofrequency devices can help remove or grow hair, but more research is needed.
Preliminary evidence indicates that bipolar and monopolar radiofrequency (RF) devices are effective for hair removal, with bipolar RF combined with intense pulsed light being particularly useful for long-term removal of body and facial hair, and monopolar RF used for eyelash removal in trichiasis patients. Conversely, fractional RF shows promise in stimulating hair growth in individuals with alopecia areata and androgenetic alopecia. Further research is necessary to better understand the efficacy, mechanisms, and optimal parameters of RF devices for different hair-related applications.
January 2019 in “Acta dermatovenerologica Alpina, Pannonica et Adriatica (Tiskana izd.)” Non-ablative radio frequency can potentially increase hair count in men with androgenetic alopecia, but some may be bothered by the smell during treatment.
