RO Poor growth is a yield problem, not a healing problem. The grafts were placed; a share of them never produced hair. Nothing about the scalp on the day of surgery predicts it, and nothing in the first months distinguishes it from the normal course — transplanted hairs shed within the first two months whether they will regrow or not.
It cannot be judged before the growth phase completes. Regrowth begins around the third to fourth month and is still filling in at nine. A verdict reached at month six is a verdict on an unfinished result, which is why genuine cases are counted at twelve months and not before.
| Stage | What can cost yield here |
|---|---|
| Extraction | Follicles cut through instead of removed intact |
| Bench | Grafts dried, crushed or held too long |
| Placement | Sites too deep, too shallow, or packed too tightly |
| Patient | Smoking, uncontrolled systemic disease, poor first-week care |
The stages are cumulative and invisible to each other. A procedure can be flawless at extraction and still lose grafts on the bench. Because none of these leave a visible trace, a disappointing result is usually the sum of several small losses rather than one identifiable mistake.
Nothing regrows a follicle that did not survive. The answer to poor yield is another procedure using donor that has not yet been spent — which is why the donor left after the first session matters as much as the result of it.
