Several examinations will be performed in every visit, including history taking, physical examination, trichoscopy and trichoscan. Laboratory evaluations (complete blood count) for the measurement of the thrombocyte for baseline and PRP will be performed for all assented subjects on the first visit. Each subject will be instructed to apply 5% topical minoxidil twice a day everyday as primary therapy during the study
This research is a preliminary, randomized, double blind clinical trial, which will examine the differences in PRP preparation methods, a single-spin centrifugation of 3000 rpm in 15 minutes compared to a double-spin centrifugation of 1500 rpm in 6 minutes followed by 2500 rpm in 15 minutes, on the results of Thrombocyte Concentration and Clinical Improvement of Androgenetic Alopecia.
