Also slits condense the hairs, creating a higher density of hair which may have an inferior cosmetic appearance. Also in the frontal row, the grafts must be slightly overlapped to hide the scars and create a more subtle and natural hairline. See Figure 19-35. Here square or rectangular grafts are harvested from a rectangular donor strip. This is accomplished by using a multi-blade knife which will cut a strip of multiple rows.
Advantages are speed and ease of cutting the donor strip into individual grafts.
Scalp recipient holes are made 0.5 to 0.75 mm smaller than the donor graft. Minigrafts are placed in a random fashion over the recipient site, and into holes just slightly smaller than the diameter of the graft. The holes are placed one graft width or less apart from each other in the frontal hairline, requiring multiple transplant sessions. Micrografts are placed in front of the minigrafts to provide a transitional zone, mimicking a natural hairline. The holes and slits must be angled in the direction of the desired hairstyle.
