What determines how quickly miniaturised hair becomes bald?

I would need to know several things before
giving you a firm answer.I’m assuming
you are a male based on the words you used in your patient description.Given that, what was/is the pattern /class of
hair loss of the men in your family (at your current age). Most people are able
to find at least one male member in their last generation who have been just
like them.That helps them realize where
they are heading.The other factor is
the data we get from our microscopic evaluation of scalp (miniaturization
study). The degree of miniaturization is
directly associated with the speed of hair loss if you don’t use any hair loss
medication.So if your miniaturization
in 80% in one area you will lose hair in that area in comparison to the other
areas that you only have 30% miniaturization.

Hair miniaturizes at different rates in different people. Some bald fast and others bald slowly. In general, men who start thinning at younger ages and those who have very strong family history are most likely to thin rapidly. Also, the use of anabolic steroids can also prompt more rapid progression.

It is highly variable, some proceed quickly others more slowly. Average is about 5-15 years to be bald in area with miniaturisation.
