Abstract
Early surgical hair restoration (SHR) techniques were fraught with limitations. Major advancements and refinements have taken place yielding minimally invasive, relatively scar-free, and natural-looking hair transplantations. Our aim was to review the origins and advancements of SHR and to discuss future directions for the field. Searches were performed using: Pubmed, Scopus, and the International Society of Hair Restoration Surgery's Hair Transplant Forum International for articles related to SHR. Reference sections of articles obtained were reviewed. Relevant textbooks obtained were reviewed. SHR techniques originated as macro-level graft transplantations and excision of scalp tissue. They progressed toward micro-level graft transplantations performed with extreme caution and precision. However, all SHR techniques are limited by their reliance on existing donor hair to fill balding areas. Further advancements in hair follicle cell cloning and regeneration of growth may offer a solution to this overarching limitation.
