The effect of autologous activated platelet-rich plasma injection on female pattern hair loss: A randomized placebo-controlled study.
/
RESULTS:
There was a statistical significant difference between PRP and placebo areas (P<.005) regarding both hair density and hair thickness as measured by a folliscope. The hair pull test became negative in PRP-injected areas in 25 patients (83%) with average number of three hairs. Global pictures showed a significant improvement in hair volume and quality together with a high overall patient satisfaction in PRP-injected sites, and these results were maintained during the 6-month follow- up.
CONCLUSION:
Platelet-rich plasma injections can be regarded as an alternative for the treatment of female pattern hair loss with minimal morbidity and a low cost-to-benefit ratio.
