TLDR Using a carbon dioxide laser and platelet-rich plasma together can effectively restore hair and patients are generally satisfied with the results.
The study assessed the effectiveness of fractional carbon dioxide laser followed by platelet-rich plasma application on hair regrowth in seven participants with androgenetic alopecia. The participants underwent ten treatment sessions every two weeks with a 12-week follow-up. The study found that both groups showed significantly increased total and terminal hair densities during treatment compared to baselines. The mean total hair density increased significantly more with high pulse energy (1.42 hair/cm2) compared to low pulse energy (1.04 hair/cm2) throughout the study period (p = 0.023; 4.89 hair/cm2). Patient satisfaction scores demonstrated improvement, with statistical significance (p = 0.029). The average pain intensity scores were not different between the groups (p = 0.760). The adverse events were minor and well tolerated. The study concluded that this synergistic treatment leads to hair restoration and high patient satisfaction, with the parameters of 22-mJ beam energy with 400 spots/cm2 density being superior to 12-mJ beam energy with 800 spots/cm2.
