Hair loss is one of the most common conditions encountered in both clinical and aesthetic medicine, and its impact often extends well beyond the physical appearance of patients. While surgical restoration has traditionally garnered the most attention, the field of nonsurgical hair restoration has expanded significantly—driven by advances in molecular biology, the development of new therapeutic modalities, and increasing demand for lower-risk, patient-tailored treatments.

This book was written to provide a comprehensive, evidence-based overview of nonsurgical approaches to hair restoration. It is intended for clinicians, trainees, and specialists seeking a deeper understanding of the available tools and how to use them effectively.
