Actual Process of a Dying Hair?

Hello,

I had a brief question about the miniaturization or actual process of hair loss:

When one has a hair fall out (sheds), is that the last hair that particular follicle will produce? Or, does another hair replace the shedded hair, but in a slightly minaturized form, starting the process over again as the hair gradually gets thinner (diameter)until it’s no longer cosmetically viable?

Thanks in advance.

Genetic hair loss causes progressive miniaturization of the hair shaft. Eventually, when the hair goes into telogen (sleep phase) it just will not grow back, because it has died (apoptosis is the term for a cell that has reached the end of its lifetime).
