Graft Implantation Angle

Angle and direction are two separate decisions. Angle is how steeply the hair leaves the skin; direction is where it points once it is out. A graft can have a perfect angle and still look wrong because it is aimed the wrong way, and the two are set independently at every single recipient site.

Native hair is rarely upright. Across most of the scalp it emerges lying forward at an acute angle, flattest at the frontal hairline and in the temples, and steeper only as it approaches the crown. Grafts placed more upright than their surroundings catch light differently, stand away from the scalp and read as planted — the effect people describe as doll-like long before they can say why.

Angle also protects the hair that is already there. Following the exit path of surrounding native hairs keeps the blade away from their shafts and roots. Sites cut across that path damage what they pass through, so a wrong angle can cost existing density as well as making the new hair look artificial.

It is decided once. The channel fixes the angle; the graft can only follow it. Nothing about the direction of growth can be corrected afterwards without removing the graft.
