Studysummary This study reviews the potential of rosemary for hair loss treatment, highlighting its beneficial bioactive compounds that may support healthier scalps and promote hair growth, though inconsistencies in formulations and lack of long-term safety data suggest more research is needed. Our plain-language summary of this paper — not a Tressless recommendation.
This paper explores the potential of rosemary (Rosmarinus officinalis) in addressing hair loss and promoting hair growth, particularly in cases of androgenetic alopecia (AGA). Rosemary's bioactive components, such as 1,8-cineole, rosmarinic acid, and carnosic acid, are noted for their ability to enhance microcapillary circulation, inhibit testosterone 5α-reductase, and provide antibacterial, anti-inflammatory, and antioxidant effects, all of which contribute to a healthier scalp and hair follicle renewal. While preclinical and clinical studies show promise, challenges like small sample sizes, inconsistent formulations, and insufficient long-term safety data persist. The paper suggests that 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.
