Review on natural remedies for hair growth promotion with a focus on rosemary

The increasing prevalence of hair loss, particularly among men, has led to a growing interest in natural remedies. Among these, Rosmarinus officinalis leaf extract (rosemary) has gained attention for its potential hair growth-promoting properties. This review examines the efficacy of some natural remedies, with a focus on rosemary extract, in stimulating hair growth in patients with androgenetic alopecia (AGA). In contrast to conventional treatments like minoxidil and other chemical remedies, which often come with undesirable side effects such as scalp irritation, systemic effects, and potential dependency, rosemary offers a more natural alternative with fewer adverse effects. Using both in vitro and in vivo models, the research assesses the extract's efficacy in enhancing hair follicle proliferation and extending the anagen phase of hair growth. Clinical trials demonstrated significant improvements in hair density and thickness among participants using rosemary extract compared to control groups. These findings suggest R. officinalis leaf extract may serve as a viable natural alternative for hair loss treatment, warranting further investigation into its mechanisms and long-term benefits. This review highlights the need for further research into natural remedies, as well as rosemary's long-term efficacy and safety, positioning it as a promising candidate for those seeking a safer approach to hair restoration.
