Hairline design principles

What are the principles of natural hairline design?

A natural hairline follows five principles: irregularity rather than a straight line, a gradual transition zone thickening from single hairs at the front, single-hair grafts only at the leading edge to avoid a tufted look, height set by facial proportions, and a shape suited to the face, including temple angles and any widow's peak.

• Irregularity. Natural hairlines are ragged, with small clusters and gaps. A straight line reads as artificial instantly.
• A transition zone. The leading edge is single hairs at low density, thickening gradually behind. There is no sharp boundary in nature.
• Single hairs at the front. Multi-hair grafts placed at the leading edge produce a tufted, pluggy look.
• Appropriate height. Positioned relative to facial proportions, not to where hair used to be.
• Shape suited to the face, including temple angles and any widow's peak.

Why should a hairline be designed for the future rather than for today?

A hairline placed too low looks good at thirty but increasingly odd at fifty, once loss behind it has progressed and donor supply to support it is spent. A conservative hairline uses fewer grafts, leaves reserve for later loss, and stays plausible as loss advances, the most common disagreement between patients and surgeons.

What are the warning signs in a proposed hairline design?

Warning signs include a straight, sharply defined edge; a hairline placed lower than the patient's original one; no discussion of future loss or donor capacity; a promise to restore a juvenile hairline in an older patient; and refusal to draw the design and show it in a mirror before shaving.

• A straight, sharply defined edge
• A hairline lower than the patient's original one
• No discussion of future loss
• No mention of donor capacity
• A promise to restore a juvenile hairline in an older patient
• Refusal to draw the design and let you see it in a mirror before shaving

What should a patient do at the hairline consultation?

At consultation, ask to see the drawn hairline in a mirror from both the front and in profile, and ask directly how it will look at Norwood 6. A surgeon who cannot answer that question has not adequately planned the hairline design.
