The analysis

Six parameters. One objective picture of the scalp.

Every Trichora scan returns the same structured set of findings, so two visits — or two clinics — are always comparing like with like.

Parameter 01

Hairline recession map

From the front view, Trichora traces the current hairline and compares it with the expected position for the patient's facial proportions. The gap between the two — across the mid-forehead and both temple corners — is drawn as a contour the patient can see at a glance.

  • Output

    Annotated front image with expected vs. actual hairline

  • Why it matters

    Temple recession is the earliest pattern most patients notice last

Front view with expected and actual hairline

Parameter 02

Baldness grade, 1 to 7

The hairline map, temple-corner recession and crown involvement combine into a single clinical staging grade every dermatologist already speaks. Select a stage to see the scalp and what Trichora reports for it.

Top view of a man's scalp at Norwood grade 3: M-shaped temple recession
Grade 3 — Deep temple recessionRecession about 3 cm deep forming a clear M. Frontal corners bare; top and crown still full. The earliest stage considered clinically significant.

Female pattern · Ludwig I–III

Women are staged on their own scale.

Female-pattern loss keeps the hairline and widens the parting, so a 1–7 recession grade would mis-stage every woman. Trichora reports women on the three-stage Ludwig scale from the same top view.

Ludwig II — Diffuse thinningParting widened to 2.5–3 cm with diffuse thinning across the top. Scalp clearly visible through the hair. The front hairline is fully preserved.

Parameters 03 & 04

Zone thinning, scored 0–100%

From the top view, the scalp is read as three zones — frontal, mid-scalp and crown. In each, Trichora outlines the region of density loss and scores how much scalp shows through, from 0% (full coverage) to 100% (fully exposed).

    0%Full densityNo scalp visible through hair

  • Frontal

    The band behind the hairline. Often the first zone to thin and the one patients notice in the mirror.

  • Mid-scalp

    The bridge between front and crown. Scored independently so a healthy bridge doesn't hide what's happening behind it.

  • Crown

    The vertex. Invisible to the patient, visible to everyone else — and the zone most often under-treated.

Male pattern · TR-2041Front 50 · Mid 25 · Crown 75
Male pattern top view with zone contours
Recession from the hairline inward, plus a separate crown focus. Hairline graded 3.
Female pattern · TR-2038Front 25 · Mid 50 · Crown 50
Female pattern top view with parting contour
Diffuse widening along the parting; hairline intact. Same zones, same scale, different story.

Parameters 05 & 06

Temporal and occipital flags

From the left, right and back views, Trichora checks the band above each ear and the nape and lower crown for any thinning. These regions are reported as present or absent rather than scored — a clear early-warning signal and a check on donor-area integrity before any transplant conversation.
