The Rise of Cosmetic Dermatology: A Bibliometric Overview of Hair Loss Treatment Innovations

Abstract

The field of cosmetic dermatology has witnessed significant advancements over the past two decades, particularly in the realm of hair loss treatment. This study provides a comprehensive bibliometric overview of global research trends, innovations and emerging therapies in hair loss management within cosmetic dermatology. The primary objective is to evaluate the evolution, impact and direction of scientific literature related to hair loss treatments, identifying influential publications, authors, institutions and trending topics. A systematic search was conducted using the Scopus and Web of Science databases, extracting publications from 2000 to 2024. Bibliometric indicators such as publication volume, citation analysis, co-authorship networks, and keyword co-occurrence were analyzed using tools like VOSviewer and Biblioshiny (R Studio). Text mining techniques were also employed to identify evolving themes and technological breakthroughs such as platelet-rich plasma (PRP), stem cell therapy, low-level laser therapy (LLLT), and oral/topical agents including minoxidil and finasteride. Results reveal a consistent rise in publication output over the last decade, with notable contributions from dermatology and plastic surgery departments across the U.S., China and South Korea. PRP and stem cell-based interventions emerged as the fastest-growing research areas, while traditional therapies like minoxidil and finasteride remain highly cited. Co-authorship networks indicate growing international collaboration, particularly in clinical trial-based research. In conclusion, the bibliometric and text mining analysis highlights an evolving focus toward regenerative and minimally invasive treatments in cosmetic dermatology. These findings offer valuable insights for researchers, clinicians and industry stakeholders aiming to innovate and align with emerging trends in hair restoration therapies.
