Abstract (original English)

Androgenetic alopecia (AGA) is the most common type of hair loss. Platelet-rich plasma (PRP) and mesotherapy (MZT) injections of various solutions fortified with growth factors are popular treatment options for AGA. The aim of this study was to compare the efficacy of RPP and MZT products in the treatment of AGA. This retrospective study included 72 AGA patients treated with two PRP formulations and two MZT products, administered manually or with a gun injector. Hair parameters (hair thickness, hair density, and hair count) on frontal and vertex areas were measured before and after 6 months. Over 6 months, trichoscopic parameters showed significant intragroup and intergroup variability. MZT1 and PRP2 groups exhibited statistically significant improvement in most parameters, while MZT2 significantly increased vertex hair density. Hair thickness changes differed significantly between PRP1 and PRP2 groups (unadjusted p value <0.001) and possibly between MZT1 and PRP1 groups (unadjusted p value = 0.049) in both regions. Injections of PRP and MZT formulations can significantly enhance trichoscopic parameters in AGA patients within a 6-month period, but the extent of improvement varies among different PRP and MZT products.
