The Norwood Scale: How to Read Your Hair Loss Stage
The Norwood scale is the standard system for grading male pattern baldness, running from Stage 1 (no real loss) to Stage 7 (extensive loss). Knowing your stage matters because hair loss treatment is far more about preserving what you have than regrowing what’s gone, so the earlier you identify and act, the better your result.
The single most useful takeaway: don’t wait for an advanced stage to start.
What the Norwood scale is
The Norwood scale (sometimes Norwood-Hamilton) is the common language doctors use to describe how far male pattern baldness has progressed. Rather than vague terms like “a bit thin,” it gives specific stages that track the typical pattern of loss, receding hairline first, then the crown, eventually meeting in the middle. Knowing your stage helps set expectations and choose the right approach.
The stages, simplified
- Stage 1. No significant recession, essentially a full head of hair.
- Stage 2. Slight recession at the temples, a “maturing” hairline. Often the first real sign.
- Stage 3. Deeper temple recession, the first stage widely considered true balding. A “Stage 3 vertex” variant adds early crown thinning.
- Stage 4. More pronounced recession and clear crown loss, with a band of hair still separating the two.
- Stage 5. The band between hairline and crown narrows as the two areas expand.
- Stage 6-7. The bridge is gone; extensive loss across the top, leaving mainly the back and sides.
Why the pattern is so predictable
The recede-then-crown pattern isn’t random. It follows the map of which follicles are genetically sensitive to DHT, the hairline and crown, while the back and sides are typically DHT-resistant and stay put. That’s the mechanism we explain in DHT and hair loss, and it’s also why hair transplants use those resistant follicles from the back.
Why your stage changes your strategy
Here’s the crucial part. Hair-loss medication is much better at keeping hair than regrowing it. Follicles that are miniaturized but still alive can often be revived; follicles that are fully gone cannot. So:
- Early stages (2-3): the best time to act. Treatment can halt progression and often thicken things back up, protecting a lot of hair.
- Middle stages (4-5): treatment still helps preserve remaining hair and may partly regrow, but more has been lost.
- Advanced stages (6-7): medication mainly holds the remaining hair; regrowth of long-gone areas is unlikely, and transplant becomes the main option for restoration.
This is why catching it early is the single biggest factor in a good outcome.
The best stage to start is now.
Wherever you are on the scale, protecting your remaining hair means addressing DHT. HermanRx connects you with licensed physicians who can prescribe finasteride and minoxidil to do exactly that.
What to do once you know your stage
Identifying your stage is only useful if it prompts action. At almost any stage, the core plan is the same: block DHT with finasteride to stop progression and stimulate growth with minoxidil. The earlier your stage, the more you have to protect, which is exactly why waiting is the costly choice. If you’re weighing surgery down the line, our guide to hair transplant vs medication explains why you’ll still need treatment either way. Providers like HermanRx can start you on the medical foundation.
The Norwood scale grades male pattern baldness from 1 to 7 and follows the predictable DHT-driven pattern of hairline then crown. Because treatment preserves far better than it regrows, your stage should push you toward acting sooner rather than later. Identify where you are, then address DHT before more follicles are lost for good.
Frequently asked questions
What is the Norwood scale?
It’s the standard system for grading male pattern baldness, from Stage 1 (no real loss) to Stage 7 (extensive loss), tracking the typical pattern of hairline then crown recession.
What stage should I start treatment?
As early as possible, ideally at the first real signs (Stage 2-3). Treatment preserves hair better than it regrows it, so acting early protects far more.
Can medication reverse advanced stages?
Largely no. Fully lost follicles can’t be revived by medication, though it can hold remaining hair. At advanced stages, transplant becomes the main restoration option.
Why does hair recede in that specific pattern?
Because the hairline and crown follicles are genetically sensitive to DHT, while the back and sides are resistant. The pattern follows that map of sensitivity.
