Dr. Alexander has used custom-cut blades since he began hair restoration in 2003, a method he adopted from one of the surgeons who pioneered it. Most practices use generic blades. The differences matter.
Shape.The blades are chisel-cut — flat across the base, matching the actual geometry of a hair follicle. The base of a follicle is straight across, not pointed. A pinpoint blade has to go deeper to achieve the required width at the follicle’s base. Greater depth means disruption to the surrounding tissue. A chisel-cut blade reaches the correct width at the exact depth required — and no deeper.
Sizing. Each blade is cut to match both the width and the length of the follicle it will receive. The incision is only as wide as the follicle and only as deep as the follicle. No more. This custom-cut blade placement method is sometimes referred to as the lateral-slit technique. It allows Dr. Alexander to pack grafts at high density. For some patients, that density can mean their goals are achievable in a single session rather than multiple procedures, depending on donor characteristics and the area to be covered.
When a graft fits its recipient site precisely, it locks into position. It cannot shift or float as the wound closes. The angle Dr. Alexander sets into the blade is the angle the hair grows. It does not drift during healing.
With generic, oversized blades, the graft floats in the channel. As the incision heals, it pulls the graft in whatever direction the tissue happens to close. The result is off-axis hair — the signature look of a procedure done for speed rather than precision.
Smaller, precisely sized incisions also allow Dr. Alexander to place recipient sites closer together and to work between existing hairs without disturbing them. Working between existing hairs without disturbing them in this way is also designed to help reduce shock loss to those hairs during placement.
