TLDR PRP injections improve hair density in men with hair loss, with few short-term side effects.
The study found that platelet-rich plasma (PRP) injections can be a safe and effective treatment option for men with androgenetic alopecia (AGA). The study included 30 males who received 3 PRP injections at one-month intervals. Hair density increased by 19.17% following the intervention, and the improvement was sustained at 4 months. The study concluded that PRP injections have a favorable effect on hair density in male patients diagnosed with AGA, with minimal short-term side effects.
