What happens to a receding hairline

[mattj]

To be honest I'm not entirely sure that the miniaturization process always fits with the normal phases of hair growth, shedding, resting and renewal. Some guys lose hair very fast and at a rate which seems to exceed the cycle. In other words, it appears to me like they lost hair too quickly for it to have gone through even one full cycle of being shed and then growing back thinner.

That's just an observation that I've never seen explained in any of the literature. I suspect that some follicles in some men might never produce a miniaturized hair if the process is very rapid.
