Norwood 6: Hairline Design Principles for This Stage

February 23, 20265 min read1,200 words

Hairline design at Norwood 6 is the most consequential decision in the entire transplant process. The hairline is the first thing people see, it frames the face, and it determines whether the result looks natural or artificial. At Norwood 6, where donor supply is limited and the coverage area is large, every design choice has amplified consequences.

Why Hairline Design Is Harder at Norwood 6

At earlier stages (Norwood 2 to 4), the hairline design works within a relatively small recipient area. Native hair often remains in the mid-scalp and crown, providing context and blending naturally with transplanted grafts.

At Norwood 6, the surgeon is building from a blank canvas. There is no existing frontal hair to blend with. The entire hairline, mid-scalp transition, and crown must be planned as a single coordinated system using a finite number of grafts (4,000 to 6,000).

The design must balance three competing demands:

  1. Natural appearance: The hairline must look age-appropriate and biologically plausible
  2. Coverage breadth: Grafts must stretch across a large area without leaving obvious gaps
  3. Donor conservation: Every graft used in the hairline is one fewer available for the mid-scalp and crown

Getting this balance wrong is the leading cause of poor outcomes at Norwood 6.

Principle 1: Hairline Height and Position

The most common mistake in Norwood 6 hairline design is placing the hairline too low. A low hairline demands more grafts to fill the larger frontal zone, steals grafts from the mid-scalp and crown, and looks unnatural on a patient with age-appropriate facial features.

Recommended hairline height at Norwood 6:

Age RangeRecommended Height Above Mid-BrowRationale
30-407.5-8.5 cmSlightly higher than youthful; allows for natural aging
40-558-9 cmMature position; matches age and face structure
55+8.5-9.5 cmConservative; prioritizes natural look over maximum coverage

These measurements are taken from the midpoint between the eyebrows (glabella) to the new hairline. Placing the hairline 1 cm higher than initially requested often produces a more satisfying long-term result because it frees 300 to 500 additional grafts for mid-scalp density.

The hairline shape should follow the natural frontotemporal recession pattern of a mature male hairline, not the rounded juvenile hairline of a teenager. A slight M-shape with gentle temporal recession is more natural on an adult face.

Principle 2: Micro-Irregularity at the Border

Natural hairlines are not straight lines. They feature subtle irregularity, with individual hairs at varying depths, angles, and densities along the border. Recreating this at Norwood 6 requires specific technique.

How surgeons create micro-irregularity:

  • Single-hair grafts at the front: The first 1 to 2 rows of the hairline use only single-hair follicular units (1-hair grafts). These create a soft, feathered edge rather than an abrupt wall of density.
  • Varied angles: Grafts along the border are placed at slightly varying angles (8 to 15 degrees from the scalp surface), mimicking the natural randomness of a real hairline.
  • Staggered depth: Rather than a uniform row, the leading edge of the hairline has some grafts placed 2 to 3 mm ahead of others, creating a zig-zag pattern visible only at close inspection.
  • Density transition: The first row is sparse (15 to 20 grafts/cm2), increasing to full target density (35 to 40 grafts/cm2) over 1 to 1.5 cm. This gradient prevents the "wall of hair" appearance.

A surgeon who draws a perfectly straight, uniform line at the consultation is a warning sign. Natural hairlines do not look this way.

Principle 3: Density Zoning

At Norwood 6, uniform density across the entire recipient area is not achievable with available donor supply. Strategic density zoning allocates grafts where they create the most visual impact.

Standard density zoning for Norwood 6:

ZoneTarget Density (grafts/cm2)PriorityRationale
Hairline border (first 1 cm)15-25 (transitional)HighestDefines the edge; must look natural up close
Frontal zone (behind hairline, 3-4 cm)35-40HighestMost visible zone; frames the face
Mid-scalp25-30HighCreates continuity between front and back
Crown20-25ModerateVisible mainly from above; can be deferred

This zoning creates a natural density gradient. Hair is densest where it is most visible (front and center) and gradually reduces toward the back, which is how natural hair patterns work in many men over 40.

Principle 4: Temporal Points and Framing

The temporal points (the small triangles of hair that connect the hairline to the sideburns) are frequently overlooked in Norwood 6 design but are critical for a natural frame.

Key considerations for temporal points:

  • Rebuilding temporal points requires 150 to 300 grafts per side
  • The direction of hair growth in this zone is downward and slightly forward
  • Over-engineering the temporal points wastes grafts; a soft, natural transition is more important than full density
  • Some patients choose to leave temporal points untreated and use their remaining sideburn hair as the frame

Well-designed temporal points connect the transplanted hairline to the patient's natural remaining hair, eliminating the "island of hair" appearance that can occur when the hairline floats disconnected from the sides.

Principle 5: Crown Design (If Addressed)

Crown design follows different principles than hairline design because the growth pattern is radial (hair grows outward from a central whorl) rather than directional.

Crown design at Norwood 6:

  • Whorl recreation: Grafts are placed in a spiral pattern radiating from the crown's natural center point
  • Lower density: 20 to 25 grafts/cm2 (the crown is less visible at conversational distance)
  • Smaller coverage area: Surgeons often cover 70 to 80% of the bald crown area, leaving the center slightly thinner, which mimics natural crown thinning in aging men
  • Session timing: Typically deferred to the second session after frontal results are established

Many surgeons recommend addressing the crown only after the frontal result is visible (at 12 months). This allows both surgeon and patient to evaluate remaining donor supply and adjust the crown plan based on actual (not projected) frontal results.

Principle 6: Accounting for Future Changes

At Norwood 6, the hairline design must account for the possibility of further progression to Norwood 7 and the natural aging of the patient's face.

Future-proofing considerations:

  • A slightly higher hairline ages better than a low one
  • Leaving a small buffer of untransplanted scalp above the hairline allows for minor adjustments in the future
  • Designing the hairline to look natural at 50, 60, and 70 (not just today) prevents the jarring appearance of a youthful hairline on an aging face
  • Finasteride use post-surgery protects the transition zones between transplanted and native hair

The surgeon and patient should discuss what the result will look like at 5, 10, and 20 years post-surgery, not just at the 12-month mark.

FAQ

How high should the hairline be at Norwood 6?

At Norwood 6, the hairline should be placed approximately 7 to 9 cm above the brow line (mid-brow). This is a mature, age-appropriate position that avoids the common mistake of placing the hairline too low, which wastes grafts and creates an unnatural appearance. A slightly higher hairline also reduces the total graft demand, allowing more grafts for mid-scalp and crown coverage.

Should the crown be included in a Norwood 6 hairline design?

The crown is typically addressed in a second session, not the first. The frontal hairline and mid-scalp take priority because they are more visible and create the greatest visual impact. If donor supply permits, the crown is filled at reduced density (20 to 25 grafts/cm2) in session two. Some patients opt to leave the crown untreated and use SMP or hair fibers instead.

What makes a Norwood 6 hairline look natural?

A natural-looking Norwood 6 hairline has micro-irregularity (not a straight line), uses single-hair grafts at the very front edge, transitions gradually from higher to lower density moving backward, follows an age-appropriate height (7 to 9 cm above brow), and maintains correct hair direction angles (10 to 15 degrees at the hairline, increasing toward the crown).
