Hair transplant and local anesthetics.

Hair restoration is an art and a science that requires an experienced and dedicated surgeon and team to achieve consistently superior outcomes. In addition to discussion of local anesthetic in use for hair restoration, this article emphasizes the pearls and pitfalls that are involved at every phase of the procedure including judgment, hairline design, donor harvesting, recipient-site creation, graft preparation, and graft placement. Two recent advances in the field are highlighted: the use of regenerative medicine (platelet-rich plasma and ACell), and developments in follicular-unit extraction as an alternative to traditional linear donor harvesting.
