Abstract (original English)

Hair loss, or alopecia, constitutes a significant and prevalent concern affecting individuals worldwide. Despite the availability of numerous commercial solutions, many individuals continue to experience substantial psychological distress, leading to adverse impact on personal relationships, social interactions, and occupational performance. The limitations of conventional treatments, such as oral medication with potential systemic side effects and topical applications with localized adverse events, have driven the exploration of alternative therapies. Emerging localized injectable treatments for hair regrowth (PRP, stem cells, exosomes) offer a promising avenue for addressing this persistent issue. These injectable therapies hold the potential to minimize the systemic side effects often associated with oral medications, while also mitigating the localized adverse events that can arise from topical applications. This narrative review provides a comprehensive overview of the medical state-of-the-art in off-label injectable hair regrowth treatments, delving into the diverse range of available options. A critical component of this narrative review involves a thorough evaluation of relevant clinical studies, assessing the efficacy and safety profiles of these emerging therapies. Furthermore, detailed attention is given to injection techniques and administration protocols, crucial f
