RO Every technique scars; they differ in shape, not in whether. Skin removed by a punch or a blade is replaced by scar tissue in both cases. What changes is whether that tissue is gathered into one line or scattered as hundreds of points, and each pattern hides under different conditions.
| Punch extraction | Strip harvesting | |
|---|---|---|
| Pattern | Hundreds of small round marks, usually paler than surrounding skin | One horizontal line across the back of the head |
| Becomes visible | At very short clipper lengths, or when the donor is over-thinned | Whenever hair above it is shorter than the line is wide |
| Made worse by | Larger punches and extractions taken too close together | Tension at closure and poor healing |
Scattered scarring is judged as a whole, not individually. A single extraction mark is invisible. Several hundred taken from too small an area merge into a diffusely pale, thinned patch, and at that point the problem is not the individual scars but the density lost between them.
Contrast decides visibility more than size. Pale marks on pale skin under pale hair disappear; the same marks on skin with strong hair-to-skin contrast are read from across a room. This is why donor discipline matters more for some patients than others, and why scarless describes no real technique.
