After Miniaturization Mapping, How Accurate is the Norwood Class Diagnosis?

I have ceased to be amazed by the vast amount of information this site provides to all of us hair-obsessed patrons–Kudos to you balding blog!

My question is pretty simple (i think):

How soon is one able to tell what Norwood class he will develop into? Put another way, if you’ve been mapped for miniaturization, how accurate an assesment is this of your final balding
pattern?

I think I understand your question. You want to know if the mapping of your scalp for miniaturization will indicate your eventual hair loss pattern? The mapping of miniaturization will show you more about your balding pattern than you can see with your naked eye. Most likely, you would progress to a higher Norwood classification if there is miniaturization in the areas which appear hairy and the more miniaturization present, the more likely your balding will extend to those areas. You may not completely bald in the areas where miniaturization is present and if you took drugs, that may be more likely then if you let nature take it course. If you did nothing to arrest the process of MPB, the likelihood that you will see a more advanced pattern is high. But if you use medications like Propecia, you will be slowing down the process. If you’re looking for a numerical value to show the accuracy of a hair loss pattern, I unfortunately don’t have one for you.
