I wonder how persistent the forelock is. My father – 55 now, has a receded hairline (V) shaped. It has thinned in the frontal region in recent years, but no real crown thinning.
My question: I’m 24, and already have a deep V shaped hairline, but I wonder how permanent it will remain? Or, whether the forelock can be expected to disappear as well.
Also, what extend does baldness proceed? Who makes it to a norwood 7 pattern?
You need a good diagnosis, including miniaturization mapping and a solid measurement of the hair bulk in the top and crown of your head. The same can be done for the forelock to let you know if you are actually losing hair in the forelock now. As a generality, if the forelock remains strong by the time you are 30 years old, then you may keep it into the years to come. As for percentages of men that make it to the advanced balding stages, see here.
At 24 years old, you need good metrics that should be repeated every year, and with what you report (your deep V hairline) you should consider finasteride. Talk to your doctor, as it is a prescription medication.
