What is the Norwood Scale?

Norwood Scale introduction.
You’ll have heard to the Beaufort Scale. And no doubt you’re more than familiar with the Richter Scale.
But have you any idea what the Norwood Scale is all about?
Most people will have no idea that it is something to do with hair.
When male pattern baldness begins to strike there is a dedicated measure which assesses the severity of hair-loss.
A Norwood type 7 is the most severe delineation of male-pattern hair loss. Not everyone who has hair-loss will get to a stage 7 as genetic factors may mean that you remain at one of the other six stages.
But you’ll probably never have given much thought to all the possible stages of hair-loss and what, if anything, can be done to take someone with severe hair-loss back to an earlier stage on the scale.
Here you will find a careful categorisation of the various stages of male-hair loss.
You’ll be able to check your own pattern of hair-loss against the pictures we present and work out where you sit on the Norwood Scale.
It will also give you a good idea of the further trajectory of your hair-loss and when the best time might be to start to tackle it.
Below are the different areas of the hair that can be lost in the Norwood Scale.
