Is using both alum and witch hazel after a shave redundant or overkill? If I understand it correctly, they both kind of do the same thing (outside of stopping bleeding) so I thought it was one of those "one or the other" kind of things.
I don't know that I have the 'right' answer for you; however, I have a reply for you...
I personally use both most times...Upon my final pass, I hot rinse, cold rinse, apply alum stick with damp cold face, clean up a bit, then dry face, then apply witch hazel with Aloe...
I use alum to nip any weepers in the tail and the witch hazel w/Aloe to 'condition' a bit prior to applying any AS or ASB (sometimes both)
I have a propensity to stack products quite a bit post shave...some may disagree with my methodology, but I like it...
There you have it, I think you could successfully use one, the other, or both...depends on what you like I should think.
Cheers,
Mark
+1I use alum if I have weepers, witch-hazel if I don't.

Both are astringent, but alum has disinfectant properties (why it's effective as a deodorant) and promotes clotting, while witch-hazel is known to be soothing to irritated or bruised skin.
They do slightly different things so you can use them them together - if the alum stings too much the witch-hazel will soothe it.
