i include in this question a quote you made in a recent post which i would appreciate if you could clarify:
“As hair in the maturing hairline undergoes apoptosis (cell death, possibly because the number of hair cycles in the juvenile hairline may be limited and reached), it could just fall out without going through miniaturization.”
Does this mean that if there is minaturization at the hairline change then this is MPB and not the natural development of the mature hairline? or can there be minaturization without MPB at the hairline? I would much appreciate it if you could comment further on this as this relates to the difficulties i have had in getting a professional opinion on my own hairline- as to whether its MPB or just the development of the mature hairline.
If you have a maturing hairline, I would not expect to see miniaturization from the highest wrinkle of the furrowed brow. The leading edge of a maturing hairline, as a rule, does not show miniaturization. From the few cases I can reference (nephew and two of my sons), they lost their juvenile hairlines without miniaturization appearing, so I draw my conclusion based upon those three cases in my family.
