What is Multiple follicular unit grafts?

Multiple follicular unit grafts is a hair transplant technique that has been developed to complement and enhance current micro grafting and follicular unit procedures by increasing density without sacrificing naturalness. A follicular unit is a naturally occurring bundle of hairs. This bundle contains anywhere from 1 to 4 hairs. A "multiple follicular unit" is a graft that contains more than one follicular unit. When combined these follicular units can total 5 to 8 hairs creating more significant results. These grafts are not to be mistaken with old style hair plugs harvested with a punch biopsy instrument, but instead are modern day slit grafts harvested from a thin donor strip in the back of the head and separated under magnification.
