Adipose-derived Stem Cell Conditioned Media as a Novel Approach for Hair Regrowth in Male Androgenetic Alopecia

This study was a double-blind, randomized clinical trial (RCT). Two concentrations of ADSC-CM were utilized: concentrated and non-concentrated ADSC-CM. The scalp was divided vertically in half; one side was injected with 2 ml of ADSC-CM, while the control side received 2 ml of NaCl 0,9%. After the injection, patients applied topical 5% minoxidil twice daily. Clinical improvements were assessed using photographic evaluation and trichoscan every two weeks.
