I've been de shaving for a couple of months now and my usual routine is shave, cold water rinse then rub round with an alum block before having a shower, after the shower I usually apply some proraso pre/post shaving cream because I like the effect and occasionally some aftershave balm but I use the balm a lot less now as I don't feel I need it (either my technique has improved or my skin has adapted).
I have witch hazel but don't use it and some old aftershaves which have been knocking round the house for years, I'm not keen on the effect of these as seem to add heat to my face but I have some proraso aftershave on order.
My questions are if I use aftershave can I dispense with the alum? or when I use the alum do I need aftershave? Does the witch hazel have any properties the others don't have?
