Fractional Laser Treatments in AGA

Iana Barros presented on the use of fractional laser treatments for alopecia, particularly androgenetic alopecia (AGA). She explained the potential mechanisms of how lasers promote hair regrowth, citing studies that suggest low energy and high density settings yield the best results while avoiding follicular damage. Barros highlighted the importance of combining laser treatments with first-line therapies for improved outcomes, particularly in moderate to advanced cases of AGA. Different types of lasers, including erbium glass, Tulium, and CO2 lasers, were discussed, with erbium glass showing the most evidence for therapeutic effects. Barros described her own protocol, typically involving six sessions that combine laser with mesotherapy, and noted the safety and tolerability of the treatments while emphasizing the necessity of tested parameters to avoid complications. She shared a case study of a postpartum patient successfully treated with laser alone, reinforcing the potential efficacy of fractional laser treatments. In conclusion, Barros emphasized the need for more research to establish optimal treatment protocols and encouraged the audience to consider combining different treatment mechanisms for AGA.
