Any barbers around that can answer?

And who cuts the Alpha barber’s hair? Does he do it himself or... is there something more?

Is the alpha have forever perfect hair? Is the next alpha determined by whoever cuts the current alphas hair best?

Kill the alpha, kill them all.

There is no beginning to the chain and there is no end, it loops back on itself to form a self fulfilling cycle of hair cuttery.
They say if this chain is ever broken, then the seals to hell with break too.

Ask Bertrand Russell.
