Photothermal Conditioning of Platelet-Rich Plasma: Mechanisms and Emerging Applications in Hair Regeneration

Photothermal conditioning of platelet-rich plasma (PRP) is a promising innovation in hair restoration, enhancing PRP's bioactivity through controlled electromagnetic energy. This technique may increase hair density, promote follicular regeneration, reduce inflammation, and extend the anagen phase of the hair cycle. Despite promising preliminary evidence, there is a lack of standard protocols and a clear understanding of the mechanisms. Future studies with standardized protocols and larger cohorts are needed to confirm efficacy and ensure safety, suggesting potential as a treatment for androgenic and inflammatory alopecia.
