The Norwood Scale: Stages of Male Hair Loss
A simple way to understand how far male pattern hair loss has progressed, and what it means for your options.

The Norwood scale is the standard way clinicians describe male pattern hair loss. It runs from stage 1 (no real loss) to stage 7 (extensive loss with only a band of hair around the sides and back). Knowing your rough stage helps you understand your options and plan sensibly.
It is a guide, not a diagnosis. Two people at the same stage can need very different plans depending on donor hair, age and how fast the loss is moving. That is what a proper assessment is for.
What are the stages of the Norwood scale?
Stages 1 to 2 show a maturing or slightly receding hairline. Stages 3 to 4 bring a deeper receding hairline and often thinning at the crown. Stages 5 to 6 see the front and crown join up as the bridge of hair between them thins. Stage 7 is the most advanced, with hair remaining only at the sides and back.
There is also a "type A" variant, where the hairline recedes straight back without a separate crown thinning. We work out which pattern you fit at consultation, because it changes how the grafts are planned.
How many grafts do I need for my stage?
As a rough guide, earlier stages (3 to 4) often need somewhere around 2,000 to 3,500 grafts, while more advanced stages (5 to 6) can need 4,000 to 5,000 or more, sometimes across more than one session. Your actual number depends on donor supply, the area to cover and the density you want, which we confirm in person.
How does my Norwood stage affect a hair transplant?
Your stage shapes the whole plan. In earlier stages the priority is usually rebuilding the hairline and framing the face, using grafts efficiently while there is plenty of donor hair. In later stages the donor area becomes the limiting factor, so the plan shifts to spreading a finite supply for the most natural overall improvement, sometimes prioritising the front over full crown coverage.
A good result also plans for the future. Because pattern loss can continue, a sensible design leaves room so that today’s hairline still looks natural in ten years, rather than sitting oddly if the hair behind it thins further.
Is the Norwood scale used for women?
No. The Norwood scale describes male pattern loss. Female pattern hair loss usually shows as diffuse thinning through the parting rather than a receding hairline, and clinicians grade it with the Ludwig scale instead. If you are a woman noticing thinning, our female hair loss guide is a better starting point, and a consultation will assess whether a transplant or another approach suits you.
Can you slow progression on the Norwood scale?
For many men, to a degree, yes. Medical options can help stabilise loss and hold on to existing hair, which protects the result of any transplant and can delay how far you move down the scale. We assess whether supporting your hair first, treating, or a combination is the wiser route, and we explain the trade-offs honestly rather than pushing surgery.

Frequently asked questions
What stage of the Norwood scale am I?
Look at your hairline and crown in a mirror and compare with the stages above: a receding hairline points to stage 3, added crown thinning to stage 4, and the two joining up to stages 5 to 6. It is only a guide, so a clinician assessment gives you an accurate picture and a realistic plan.
Can a hair transplant help at any Norwood stage?
Most stages can be improved, but the plan differs. Earlier stages allow a focus on the hairline and front. Advanced stages depend heavily on how much donor hair remains, so the goal becomes using a limited supply wisely for the most natural improvement. We are honest about what is achievable for your stage.
Should I wait until my hair loss stabilises?
Timing matters. Operating too early, while loss is still moving quickly, can mean chasing the loss with more surgery later. Sometimes supporting the existing hair first is wiser. We assess how stable your loss is and advise on the right time, rather than operating simply because you asked.
What is Norwood type A?
Type A is a variation where the hairline recedes steadily straight back, without a separate bald patch developing at the crown. It tends to need the grafts distributed differently, which is why identifying your exact pattern at consultation matters as much as the stage number.
Does everyone reach stage 7?
No. Many men stabilise at an earlier stage and never progress to the most advanced loss. How far you go depends largely on genetics and how early loss begins, which is why we look at the pace of your loss, not just where you are today, when planning the right time to treat.
