Norwood scale guide
The seven stages, the graft budget each one implies, and why age and donor density change the plan more than the stage number itself.
The Norwood Scale Explained: Stages, Graft Budgets and What Each Stage Means for Planning
The Norwood–Hamilton scale is the seven-stage map that clinics use to describe male pattern hair loss. It is not a diagnosis and it does not predict how far you will progress, but it is the shared language that makes a quote comparable between two clinics. If you can state your stage accurately, every conversation about grafts, price and realistic coverage becomes shorter. Use the interactive Norwood scale test to place yourself, then read the stage below.
The Seven Stages
Norwood 1. The adolescent hairline, unchanged. No recession beyond the natural juvenile line. Nothing to treat.
Norwood 2. Slight symmetrical recession at the temples, usually under a centimetre. Many men stop here permanently — this is the mature hairline rather than baldness, and it is the stage most often over-treated by clinics selling to twenty-two-year-olds.
Norwood 3. Clear temporal recession forming an M shape, deep enough to be visible at a glance. The variant Norwood 3 vertex adds early thinning at the crown while the frontal line matches stage 3. This is the most common stage at which men first book a consultation.
Norwood 4. Deeper frontal recession plus a defined bald patch at the crown, separated by a band of hair across the mid-scalp. The band is still reasonably dense.
Norwood 5. The same pattern, but the dividing band is narrow and visibly thinning. Frontal and crown areas are both substantial.
Norwood 6. The band is gone. Frontal and crown loss merge into one continuous bald area across the top of the head.
Norwood 7. Only a horseshoe of hair remains around the sides and back, and even that is often thinner than it was. Donor supply is now the limiting factor for anything at all.
Stage-by-Stage Graft Budgets
These are planning ranges from clinic practice, not promises. Actual counts move with forehead height, the size of the area to cover and — above all — donor density.
The pattern in that table is the important part: from Norwood 5 upward, planning stops being about covering everything and starts being about deciding what not to cover. Framing the face is worth more visually than filling the crown, which is why a good surgeon spends the frontal budget first.
Donor Supply Is the Real Constraint
Every graft comes from the permanent zone at the back and sides. A typical donor holds 5,000–7,000 extractable grafts across a lifetime; a low-density donor holds far fewer. Two men at Norwood 5 with the same recipient area can therefore receive very different plans, and the one with 55 FU/cm² should be told that full coverage is not available at any price.
Ask for your donor density figure in follicles per square centimetre and your surgeon's estimate of the safe lifetime extraction total. A clinic that answers with a package size instead of these two numbers is quoting supply it has not measured.
Why Your Age Changes the Plan
Norwood stage describes today. Progression describes the next twenty years, and it is the part patients under thirty routinely underestimate. A twenty-four-year-old at Norwood 3 whose father reached Norwood 6 is not a Norwood 3 case — he is a future Norwood 6 who currently looks like a 3.
Two consequences follow. A hairline designed too low at that age becomes an isolated island of transplanted hair when the surrounding zone recedes behind it. And grafts spent on the crown early leave nothing for the frontal zone later, which is the reverse of the correct priority. Medical treatment to stabilise loss before or alongside surgery is the standard advice at every stage below 5, precisely because it changes which plan is safe.
Norwood Does Not Apply to Women
Female pattern loss usually preserves the frontal hairline while the central parting widens. That pattern is graded on the Ludwig scale (I to III), and a Norwood stage is the wrong frame for it. Diffuse thinning in women also has a wider range of causes — thyroid disease, iron deficiency, post-partum shedding, medication — which need excluding before any surgical plan is discussed.
What Your Stage Should Change in a Quote
Take your stage to a quote and check three things. Does the graft count fall in the range above for your stage, or well below it while promising full coverage? Does the plan name which zones are covered and which are deferred? And is a second session mentioned for Norwood 5 and above — because a single-session promise at 6,000 grafts is either over-harvesting or an inflated count.
A stage also sets your price band. Package prices in Turkey in 2026 broadly track graft count: roughly $1,500–$2,500 for Norwood 2–3 volumes, $2,000–$3,500 at Norwood 4–5, and $3,000–$4,500 or more where two sessions are planned. Run your own figure through the graft calculator and the cost calculator before comparing clinics.
FAQ
Can I move backwards on the Norwood scale?
Not naturally. Medication can thicken miniaturised hairs and make a stage look less advanced in photographs, and surgery changes appearance, but the underlying pattern does not reverse.
What Norwood stage is too early for surgery?
Norwood 1 and most of Norwood 2. At those stages the recession is often a mature hairline rather than progressive loss, and operating before the pattern declares itself commits donor grafts to a design that may not survive the next decade.
How fast do men move between stages?
There is no fixed rate. Some men sit at Norwood 3 for twenty years; others go from 3 to 5 in five. Speed of change over the past two years is a better predictor than the current stage itself.
My crown is thinning but my hairline is intact — which stage is that?
That is usually classified as vertex-pattern loss rather than a numbered frontal stage, and it is the pattern most likely to keep expanding. Crown-only transplants are viable but consume grafts quickly, so stabilising with medication first is common advice.
