Refinements in Hair Transplantation: Micro- and Minigraft Megasession

The document from 1998 by Alfonso Barrera, M.D., reports on the advancements in hair transplantation using micro- and minigraft megasessions, which involve transplanting over 1000 grafts in a single session, typically ranging from 1500 to 2500 grafts. Barrera, who has performed over 150 procedures and experienced the procedure himself, found that these megasessions yield natural results with minimal scarring and downtime. A study of 100 consecutive cases showed a 97% satisfaction rate after a single megasession with a low complication rate. The technique is suitable for individuals with good donor hair density and is particularly effective for patients in their late 30s and older. Results from various cases with different types of male pattern baldness demonstrated positive outcomes with minimal scarring and natural-looking hair growth within a year. The author concludes that the technique is an excellent option for esthetic hair restoration, offering safety, predictability, and natural results, often in just one or two sessions, with generally acceptable hair density that can be increased with additional sessions, although not beyond a third session.
