Designing the Hairline
The hairline is the part of a transplant everybody sees and the part most likely to go wrong, and the thing that decides it is a pencil drawing made before you are anaesthetised. Everything else in the operation can be adjusted, repeated or added to. The line cannot be moved back up.
Two failures account for almost every bad transplant you have ever noticed. The line was set too low, and the line was too regular. Both are design decisions, both are made in a consultation room, and both are entirely avoidable.

Where a hairline is supposed to sit
Nobody keeps their childhood hairline. Somewhere in the twenties, almost every man's hairline matures, rising a centimetre or two and receding at the corners into a shallow V. That is not hair loss. It is the adult position, and it is where a transplanted hairline should be built.
Surgeons work from the face rather than from the old hairline. The common method divides the face into three roughly equal parts, from the hairline to the brow, the brow to the base of the nose, and the nose to the chin, and places the hairline where that top third comes out even. Another common check puts the midpoint of the hairline somewhere around four fingers' width above the brow, though faces vary enough that no number survives contact with an actual head.
What matters more than the formula is the direction of the argument. The patient almost always wants it lower. The surgeon almost always argues for higher. In that disagreement, the surgeon is protecting you from a decision your fifty-year-old self would not make.
Before you agree to a design
Find a photograph of yourself at twenty-two and one of your father or uncles at sixty, and bring both. Where a hairline has already travelled and where your family's hairlines end up are the two most useful pieces of evidence in the room.
Why lower is worse
A low hairline is cheap to promise and expensive to own. It costs more grafts, because the area to cover is bigger and the hair in front of it has to be dense to look like anything.
It also spends grafts on the wrong ground. Loss continues behind the transplanted line, so a low hairline built at thirty tends to end up as a band of transplanted hair with thinning behind it, which is the hardest of all patterns to repair.
And it ages badly. A hairline that suits a thirty-year-old face on a full head looks incongruous on a sixty-year-old face with a receded temple either side of it. You cannot move it up. The only correction is removing grafts one by one, which is slow, costly and imperfect.
There is a sharper version of this problem for anyone whose family history points at extensive loss. A conservative line leaves donor hair in reserve for the loss that has not happened yet. A low one spends it in advance.
What makes a hairline look real
Irregularity, mostly. A natural hairline is not a line at all. It is a zone a centimetre or so deep, ragged at the edge, with hairs of different lengths and a scattering of isolated hairs and small clumps in front of the main mass.
The rules good surgeons work to are consistent. Single hairs only at the front edge, because multi-hair grafts there look like doll's hair and cannot be hidden. Multi-hair grafts behind them to build density. A soft transition rather than a wall. Irregular macro shape, with gentle peaks and troughs rather than a straight line or a smooth arc.
Angle is the other half. Hair at the front of the scalp grows forward and slightly downward, almost lying against the skin, and sites have to be made at that angle. Hair planted too upright stands away from the scalp and catches the light, and it is one of the tells you can spot across a room once you know it.
Temple points matter too, and are often forgotten. A frontal hairline with no temple structure either side reads as a wig, because the shape of a real hairline is defined as much by its corners as by its middle.
At the consultation
Ask the surgeon to draw the line and then hand you a mirror while you sit upright, not reclined. A hairline looks completely different on a tilted head, and this is the last moment at which the decision is still yours.
What it costs in grafts
A hairline alone, meaning a narrow band restoring the front edge, is often 800 to 1,200 grafts. A hairline plus the frontal third behind it, which is what most people actually need, is commonly 2,000 to 2,500.
Against a lifetime supply of roughly 6,000 to 8,000, that is a substantial share, and it is the share most worth spending. The frontal third frames the face and does more visible work than any other area.
Lowering the line by a centimetre can add several hundred grafts and, more importantly, commits you to defending a longer front for the rest of your life.
Getting it wrong, and what can be done
A line that is too low can be raised only by removing grafts, punching them out individually and sometimes replanting the hair further back. It works, it takes multiple sessions over a couple of years, and it costs more than the original operation.
A line that is too regular is easier. Softening it with fine single hairs planted irregularly in front of and among the existing grafts breaks up the edge and often transforms how a head reads, for relatively few grafts.
Wrong angles are the hardest to fix, because the grafts have to come out and the direction has to be rebuilt. Repair and revision covers all of this properly.
The theme across all three is that prevention is cheap and correction is not. A slow consultation is the best value in this entire field.
If you are unsure
Walk away and think about it for a month. No good surgeon will mind, the operation will be identical in four weeks, and the pressure to decide today is a sales technique rather than a clinical one.
Frequently asked questions
How low can my hairline go?
Lower than it should. The question is where it should sit, which is at your mature hairline position rather than your childhood one. See where a hairline is supposed to sit.
Why do surgeons refuse to go lower?
Because it costs more grafts, ages badly and cannot be undone. A surgeon who agrees to anything you ask for is not protecting you.
How many grafts is a hairline?
Around 800 to 1,200 for the edge alone, and 2,000 to 2,500 with the frontal third behind it. See what it costs in grafts.
What makes a transplant obvious?
A straight edge, multi-hair grafts at the front, upright angles and no temple structure. See what makes a hairline look real.
Can a bad hairline be fixed?
Partly. Softening a regular line is straightforward; raising a low one means removing grafts over several sessions. See getting it wrong.
