Can a bulk analysis predict how bald a man suffering hair loss only in the ‘receding’ pattern will end up? For me, I’m almost 100% sure I haven’t lost any density or thickness behind the hairline so how would a bulk analysis predict where my recession will progress to?
Yes and no.
The hair that is going to be lost has a biological clock with a trigger point that starts the balding process. Let’s say that someone will become a Norwood class 5 pattern balding man and that the leading edge of his frontal hairline started at 18, the remaining part of the front started at 24, and his crown started to thin at the age of 22. That means that the predicted pattern will not show until the bulk starts to reduce in those ‘triggered areas’.
When the thinning starts, the bulk measurements are clearly impacted earlier than the eye can detect, so that is the “yes” part of the answer to your question. The “no” part may reflect the crown status at the age of 20, which will not show thinning (in this scenario) until he is 22.
