Why this procedure should not be priced at the same pace as straight-haired work
The technical problem in an Afro hair transplant is geometry. A tightly curled hair does not only curl above the skin; the follicle curves beneath it as well. A punch pushed straight down around what looks like the base of a hair can therefore travel straight through a follicle that is curving away, cutting it in two. A transected follicle does not grow, and there is no way of knowing it happened until the yield disappoints a year later.
Experienced teams handle this with wider punches, slower and more deliberate extraction, manual rather than motorised punches, or by taking a strip and dissecting under microscopes where the curve can be followed by sight. All of that costs time or leaves larger marks, which is why an Afro hair transplant should be slower, and often yields fewer grafts per session, than straight-haired work at the same clinic.
A useful practical test when comparing quotes is to ask how long the clinic expects a session of a given graft number to take for curled hair specifically, then compare that against how long the same graft number would take for straight hair. A genuinely adapted approach takes noticeably longer, and a quote that promises the same graft count in the same time as straight-haired work is very unlikely to be using the slower, more careful technique that curled follicles actually need.
