Background: Hair has long held cultural and psychosocial significance, symbolizing health, status, and identity. Hair loss impacts quality of life, self-esteem, and psychological well-being. While treatments like minoxidil and finasteride exist, they often yield limited results. Hair transplantation (HT), first demonstrated by Johann Friedrich Dieffenbach in 1822, has evolved into the most effective hair restoration method. Since its inception in 1975, Dermatologic Surgery has been a main source for groundbreaking publications from major players in the field, while also playing a pivotal role in documenting the history of HT.
Objective: This mini review examines the historical evolution of HT techniques over the past 200 years, highlighting their advantages and limitations.
Materials and methods: A literature search was conducted using PubMed and Google Scholar with the term "hair transplantation techniques." Relevant sources were reviewed to extract information on technique development and historical origins.
Results: Key pioneers such as Dieffenbach, Menahem Hodara, and Shoji Okuda laid the groundwork for modern HT. Milestones include punch grafting, follicular unit transplantation (FUT), and follicular unit extraction (FUE). FUT emphasized natural follicular grouping, while FUE introduced minimally invasive methods with faster recovery and better aesthetics. Recent advancements include robotic-assisted procedures and bioengineered follicles, reflecting a shift toward precision and patient-centered care.
Conclusion: The continuous evolution of HT techniques underscores its position as the most effective method for hair restoration, particularly in androgenetic alopecia cases.
