hey there dr rassman. I have a question about miniaturization. Once a hair shows signs of miniaturization is it destined to eventually stop growing all together or can weak miniturized hair sometimes remain in that state and hang on into old age?
If so is this the basis for the head ‘mapping’ you guys do?
Miniaturized hair can reverse back to normal healthy hair or it can fall out. Or, I suspect, it can remain that way indefinitely. The percentage or how long a miniaturized hair will stay miniaturized is not well known and for genetic balding it is determined by your genes and your environment. Drugs such as finasteride (Propecia) or minoxidil (Rogaine) can reverse such miniaturization.
