RO Pitting and cobblestoning are opposite errors and are constantly confused. Both come from a graft sitting at the wrong level, but they sit at the wrong level in opposite directions and neither is treated like the other.
| Graft level | Result | How it looks |
|---|---|---|
| Below the skin surface | Pitting | Small depressions; hair emerging from a dimple |
| Flush with the surface | Correct | Hair leaving flat, even skin |
| Above the surface | Cobblestoning | Raised bumps at each graft |
The cause is depth, set at the moment the site was made. A channel cut deeper than the graft lets it sink, and the skin heals over its edges. Nothing in aftercare produces pitting and nothing in aftercare prevents it — by the time the area has healed, the level is already fixed.
It is a texture problem, not a growth problem. Pitted grafts usually grow. The hair simply emerges from a slight hollow, so the surface catches light unevenly and looks uneven when the hair is short or wet. In dense placement it reads as an orange-peel texture rather than as separate dimples.
Correction is limited, so prevention carries the weight. Once healed, options are cosmetic — resurfacing, or camouflage with pigment — and none restores flat skin completely. Calibrating depth against real grafts at the start of the procedure is the only reliable control.
