The Norwood Scale: Understanding Male Pattern Hair Loss Stage by Stage

The Norwood scale is the standard map of male pattern baldness. Knowing your stage explains what is happening, what is coming, and when a transplant makes sense.

The Norwood Scale: Understanding Male Pattern Hair Loss Stage by Stage

If you have ever tried to describe your hair loss to a clinic, you have probably wished for a shared vocabulary. That is exactly what the Norwood scale provides. It is the standard classification of male pattern baldness, and understanding where you sit on it tells you a great deal about what is happening now and what is likely to come.

What the scale describes

Male pattern hair loss, or androgenetic alopecia, follows a predictable route driven by genetics and the hormone DHT. The Norwood scale breaks that route into seven stages, from a full head of hair to advanced loss.

  • Stage 1: no significant recession, essentially a juvenile hairline.
  • Stage 2: slight recession at the temples, the classic maturing hairline.
  • Stage 3: the first clearly balding stage, deeper temporal recession, sometimes with early crown thinning (Stage 3 vertex).
  • Stage 4: more pronounced recession and a visible bald spot at the crown, with a band of hair still separating the two.
  • Stage 5: the separating band narrows as the two areas enlarge.
  • Stage 6: the band breaks down; front and crown loss merge.
  • Stage 7: the most advanced stage, only a horseshoe of hair around the sides and back remains.

Why your stage matters for surgery

The Norwood stage does more than label you. It shapes strategy. A younger man at Stage 3 whose loss is still advancing needs a plan that anticipates future recession, otherwise an island of transplanted hair can end up stranded by continuing loss behind it. Someone whose loss has stabilised at Stage 5 or 6 can be planned with more certainty, though donor supply becomes the limiting factor.

Reading the trend, not just the snapshot

Because androgenetic alopecia progresses over years, a single photograph is less useful than a trend. Measuring density and miniaturisation over time, as a structured analysis at trichotest.ee does, reveals how fast you are actually losing hair. Armed with that trajectory, the surgeons at Rubenhair can design a hairline that still makes sense as you age, not just today.
