Phytotherapeutic Potential of Rosemary in Hair Growth and Hair Fall Prevention: Mechanisms, Efficacy, and Future Perspectives

The paper explores the potential of rosemary (Rosmarinus officinalis) in preventing hair loss and promoting hair growth, particularly in cases of androgenetic alopecia (AGA). It highlights the bioactive components of rosemary, such as 1,8-cineole, rosmarinic acid, and carnosic acid, which enhance microcapillary circulation, inhibit testosterone 5α-reductase, and offer antibacterial, anti-inflammatory, and antioxidant effects. These properties contribute to a healthier scalp and hair follicle renewal. Although preclinical and clinical studies show promising results, challenges like small sample sizes, inconsistent formulations, and insufficient long-term safety data persist. Future research should aim to standardize extraction and formulation methods and conduct large-scale, long-term clinical trials to better understand rosemary's therapeutic potential for hair restoration.
