Abstract (original English)

Platelet-rich plasma (PRP) is an autologous platelet concentrate in plasma enriched with growth factors that may stimulate tissue regeneration, collagen formation, re-epithelization, and angiogenesis. PRP is widely used as an androgenetic alopecia treatment option. The present work aims to test the efficacy of various PRP methods, including those with single-spin and double-spin centrifugation. We performed a review of articles published from 2011 to 2021 in PubMed and ScienceDirect. The studies vary in the preparation procedure, dose, number, intervals between the procedures, and the injection technique because of low standardization of PRP preparation, complicating the evaluation of the clinical efficacy of the method. Based on the conducted statistical analysis, we came to the conclusion that the double-spin PRP preparation method was superior to the single-spin technique, which may be taken into account for AGA management.
