Abstract
BACKGROUND AND OBJECTIVES: Platelet-rich plasma (PRP) has received growing attention as a valuable therapeutic tool in androgenetic alopecia (AGA). However, knowledge regarding specific effectiveness and satisfaction of PRP for different grades of AGA in male pattern hair loss (MPHL) and female pattern hair loss (FPHL) is missing. This study aims to ascertain and compare the efficacy and safety of PRP treatment for different grades of AGA in males and females over 6 months. METHODS: In this study, 51 MPHL patients with Norwood-Hamilton stage II-V and 42 FPHL patients with Ludwig stage I to III were enrolled for 6 monthly sessions of PRP injections. A longitudinal analysis was used to compare the hair density, thickness, and hair pull test over 6 months for MPHL and FPHL through generalized estimating equation (GEE) models. Phototrichograms of scalp inflammation and oil secretion, global photographs and overall patient satisfaction were also assessed. RESULTS: Consequently, improvement of hair density, hair thickness, hair pull test, the level of scalp inflammation and oil secretion were observed with statistical significance in all stages for both MPHL and FPHL at 6 months. Noteworthy, lower level of alopecia (Grade II, III in MPHL and Grade I in FPHL) had better response to PRP, and also had a better tendency of increment of hair growth than that of high-grade patients with prolonged treatment. CONCLUSIONS: PRP injections, as an efficacious and reliable therapy, can be recommended for Grade II and Grade III in MPHL and Grade I in FPHL.
