The Norwood Scale Explained
Written by the Fix My Hair Editorial Team · Clinician-reviewed by Dr Hisham Band · GMC No. 7550130 · Last reviewed 3 Feb 2026Most men are poor judges of their own hair loss. You see it every day — which means you adjust gradually rather than seeing the full picture.
What the scale measures
The Norwood Scale maps male pattern loss across seven stages, from a full head of hair (stage 1) to extensive loss (stage 7). It gives clinicians a shared language for where you are and where you’re heading.
Where most men sit
The majority stabilise somewhere between stages 3 and 5. Earlier stages generally give better, more natural-looking outcomes because there’s more native hair to blend with.
Why your stage isn’t everything
Your stage doesn’t dictate your options — your donor supply does. Two men at the same stage can have very different plans depending on the density at the back and sides.
What the Norwood scale is
The Norwood scale (sometimes Norwood–Hamilton) is the standard system doctors use to classify male pattern hair loss. It runs from Stage 1 (a full head of hair, no recession) to Stage 7 (extensive loss, with hair only at the back and sides). It gives clinicians and patients a shared language for describing exactly how far loss has progressed — and it’s the starting point for planning any treatment.
The stages explained
- Stage 1 — no significant recession; the adolescent hairline.
- Stage 2 — slight temple recession; a mature hairline, often not true loss.
- Stage 3 — the first clearly balding stage: deeper temple recession (“Stage 3 vertex” adds crown thinning).
- Stage 4 — more pronounced recession and a thinning crown, with a band of hair still separating the two.
- Stage 5 — the band between front and crown narrows as both areas enlarge.
- Stage 6 — the band largely disappears; front and crown loss merge.
- Stage 7 — the most advanced: only a horseshoe of hair at the back and sides remains.
Where most men sit
Most men seeking treatment fall between Stages 3 and 5 — enough loss to be bothersome, with enough donor hair remaining to do something effective about it. Earlier stages are often best managed medically to hold the line; later stages need careful planning, because the area to cover is large relative to the donor available.
Why your stage shapes your options
Your Norwood stage guides what’s realistic. Earlier stages (2–3) often respond well to medication alone, sometimes avoiding surgery for years. Mid stages (3–5) are the sweet spot for a transplant, where a defined area can be restored from a healthy donor. Advanced stages (6–7) can still be treated, but expectations must match the donor supply — full coverage may not be possible, and priorities (hairline and front first) come into play. It also informs how many grafts you’re likely to need.
Why your stage isn’t everything
The scale describes the pattern, not the whole picture. Two men at the same stage can need very different plans depending on donor density, hair calibre, age, rate of progression and goals. A high Norwood number isn’t a barrier to a good result, and a low one doesn’t guarantee an easy one. It’s a useful map, not a verdict — the personalised plan comes from assessment.
What about women?
The Norwood scale is for men. Female pattern loss follows a different, more diffuse pattern and is graded on the Ludwig scale instead — one more reason female hair loss is assessed differently.
Common questions
What Norwood stage am I? A clinician can place you precisely, but broadly: temple recession only is early, a thinning crown with recession is mid, and merged front-and-crown loss is advanced.
Can you treat a high Norwood stage? Yes — though advanced stages need realistic planning around the donor available; medication plus a prioritised transplant is common.
Key takeaways
- 7 stages, from no loss to complete baldness
- Most stabilise between stages 3–5
- Earlier stages give better outcomes
- Stage doesn’t dictate options — donor supply does
- Professional assessment is the only accurate staging
