The donor area — the back and sides of the scalp from which follicular units are harvested — is one of the most important considerations in hair transplant planning and one of the most frequently asked about by patients in the post-operative period.
Immediately after an FUE procedure, the donor area will appear as a field of small red dots — the extraction sites — against the shaved scalp. This appearance resolves over the first week to ten days as the extraction sites heal and new hair growth from the untouched follicles begins to emerge, camouflaging the extraction pattern.
By week three to four, the donor area is typically visually indistinguishable from its pre-procedure appearance at normal hair lengths. The small dot scars left at each extraction site are typically 0.7 to 1.0 millimetres in diameter and are invisible under even a short haircut at number one or two grade.
For patients who specifically wear their hair very short — grade zero or number one — dot scars may be visible under close inspection in strong light. Most patients at these lengths choose FUE specifically to avoid the linear scar of strip surgery; the tradeoff is that very short donor area hair reveals the dot pattern more than longer styles do.
The capacity of the donor area to supply future procedures should be considered in the initial surgical plan. Taking too high a proportion of available grafts in the first session, or clustering extractions too densely in one area, can produce visible donor thinning. An experienced surgeon spaces extractions to maintain the appearance of natural donor density even after large sessions.
