Can My Hair Just Thin and Never Go Completely Bald?

Is it possible to thin out over the top of the head without ever going completely bald in that same area? Will a NW6 difuse thinning pattern always lead to a fully bald NW6?

I suppose what I’m asking is can hairs stop miniaturising once they’ve started without medication OR can a good proportion of hairs remain healthy even in an area where there are also miniaturised hairs?

Thanks.

With medication, residual hair may remain in an obvious pattern like a Norwood class 6 pattern. For those not on medications, sooner or later the pattern will advance, but the fringe area may remain.
