Abstract

Introduction Mini-invasive therapies based on autologous non-activated Platelet-Rich Plasma (ANA-PRP), Low-Level Laser Therapy (LLL-T), and Micro-Needling Technique (MN-T) used in combining for hair re-growth need to be standardized. Objectives The work aims to showin vivooutcomes resulted from retrospective case-series study in which ANA-PRP + MN-T + LLL-T were used in combined in patients affected by Androgenic alopecia. Methods 23 patients were treated, of which 13 males were classified in stage I-V by the Norwood-Hamilton scale, and 10 females were classified in stage I-III by the Ludwig scale. Assessment of hair re-growth was evaluated with photography, physician's and patient's global assessment scale, and standardized phototrichograms during a follow-up: T0 - baseline, T1 - 12 weeks, T2 - 23 weeks, T3 - 44 weeks, T4 - 58 weeks. Results Interesting outcomes represented by a hair density increase of 81 +/- 5 hairs/cm(2)and 57 +/- 7 hairs/cm(2)respectively at T1 and T2 compared with baseline (173 +/- 5 hairs/cm(2)at T1 and 149 +/- 9 hairs/cm(2)at T2 versus 92 +/- 2 hairs/cm(2)at baseline) were observed using computerized trichograms. Expert Opinion The main limitation in the autologous regenerative therapies and biotechnologies in hair-regrowth is the extreme variability of PRP products used, in the absence of standardized protocols and widely shared. Appropriate PRP preparations have to be pick after carefully thinking about their bio-molecular specifications and intended indications for use in patients.
