In light of the escalating global prevalence of hair loss, there is an imperative to explore strategies for the prevention and promotion of hair growth. This article reviews the current situation, challenges, innovations, and prospects of cosmetics that promote anti-hair loss and hair growth. Firstly, the physiological and pathological mechanisms of hair loss, including androgenetic alopecia, telogen effluvium, and alopecia areata, as well as the influence of genetic, environmental, and lifestyle factors, are explored. Subsequently, a comprehensive analysis of the predominant product categories and ingredients currently available on the market was conducted, encompassing minoxidil, finasteride, plant extracts, growth factors, and peptides. Building on this, this article further explores the challenges of anti-hair loss and hair growth promotion cosmetics, including effectiveness and safety, consumer acceptance, and the complexity of regulations and standards. This was followed by an introduction to innovations in the field, such as gene therapy, stem cell technology, and microneedling, as well as advanced delivery systems and personalized care options. Finally, this paper looks forward to future technologies' development trends and market prospects. It emphasizes the importance of multidisciplinary cooperation, including the combination of medicine and cosmetology and the integration of biotechnology and materials science. By synthesizing extant research and delineating prospective research directions, this paper establishes an indispensable reference point for the research and development of cosmetics designed to promote hair growth and prevent hair loss.Level of Evidence V This journal requires that authors assign a level of evidence to each article.
