Efficacy and Safety of Treatments in Alopecias

This thesis investigates the efficacy and safety of recent treatments for androgenetic alopecia (AGA) and alopecia areata (AA) through a literature review and two observational cohort studies. The first study involved 72 AGA patients treated with platelet-rich plasma (PRP) and mesotherapy products, showing significant improvements in hair parameters, particularly with MZT1 and PRP2. The second cohort study included 75 participants, though details are incomplete. Overall, the findings suggest that certain formulations, especially MZT1 and PRP2, are effective in improving hair density and thickness, offering promising options for managing AGA.
