Risks and downsides
A page most clinic websites keep vague. Hair restoration is elective surgery, and you are entitled to the unflattering half of the conversation before you decide anything.
Common and temporary
Swelling
Across the forehead and sometimes around the eyes, typically peaking on day two or three.
Soreness and tightness
Two to three days of sunburn-like tenderness in both donor and recipient areas.
Itching and crusting
Small crusts form around each graft and lift over seven to ten days. Itching is common as skin heals.
Numbness
Altered sensation in the scalp can persist for weeks to a few months. It almost always resolves.
Shock loss
Temporary shedding of transplanted or surrounding native hair. Usually recovers.
Folliculitis
Small inflamed spots around emerging hairs, generally easy to treat.
Less common, more consequential
Over-harvesting the donor zone. The one that cannot be undone. Taking too many follicular units from too small an area leaves the back and sides looking moth-eaten, and no procedure restores it. ISHRS guidance cautions against removing more than twenty to thirty percent of units from a single zone in one session.
Poor graft survival. Grafts that do not take, producing thin or patchy growth. Shows up around month eight, which is why follow-up access matters.
Unnatural design. A hairline placed too low, too straight, or with multi-hair grafts at the leading edge. Partially correctable, expensively.
Infection and bleeding. Uncommon in a properly run sterile setting, and a genuine reason to care about where and by whom the procedure is performed.
Continued native loss. Not a complication of surgery so much as a consequence of not planning for it — a good transplant surrounded by ongoing thinning ages badly.
Rarely the technique
When people regret a transplant it is usually not because the surgery was botched. It is because it was the wrong operation at the wrong time — performed into actively progressing loss, or planned around a graft count rather than a lifetime donor budget.
That is a planning failure, and it is avoidable. It is also why we would rather tell you to wait than take a deposit.
