    TLDR PRP treatment improves hair density and diameter in women with androgenetic alopecia.
    This systematic review analyzed the effect of platelet-rich plasma (PRP) on androgenetic alopecia in women. Six clinical trials with a total of 92 subjects were evaluated, and most studies reported a positive therapeutic effect for PRP. The results suggest that PRP treatment had a positive effect on the improvement of androgenetic alopecia, increasing hair density and improving hair diameter in affected women. However, the studies included in the review were limited by their small sample size. Overall, PRP injection is an effective and safe treatment that could be recommended for stages II and III in male-pattern hair loss and stage I in female-pattern hair loss.
