Natural hairline design: the centimetre that decides the result

How is the height of the line decided?

The hairline is positioned just above the highest point at which the forehead muscles move. The classic reference is roughly 7–9 cm above the brow; that value is then individualised according to face length, the slope of the forehead and age.

Age-appropriateness is a critical rule. Designing a 20-year-old's hairline for a 25-year-old patient leaves an artificial look at 40. Good design accounts for how the patient will look twenty years from now.

The secret of naturalness: controlled irregularity

In nature no hairline is straight as if drawn with a ruler. The front row is made of micro indentations and projections, irregular spacing and single-hair grafts.

In the second row a transition zone is built with two-hair grafts, and density increases gradually towards the back. Without that gradation you get a line that stands like a wall — and looks artificial.

• The front row must consist of single-hair grafts only.
• The transition zone is planned at a depth of at least 1–1.5 cm.
• The temple corners are left open to a degree appropriate to age.

Channel angle and direction

At the front, hair leaves the skin at a narrow angle of roughly 30–45 degrees, pointing forwards. At the crown it follows a spiral direction around the whorl.

If the channel angle is wrong the hair stands upright: it will not comb, will not lie flat, and will not look natural however dense it is. An error of angle cannot be compensated for with graft count.

The design is approved with the patient

At our clinic, once the drawing is complete the patient sees their own hairline in a mirror, it is photographed, and no channel is opened before written approval is given. That step removes most of the expectation mismatches that would otherwise surface later.
