I'm not sure this has been mentioned on the forums... I know that Nivea makes some popular after shave balms among the SR community, but I've recently discovered L'Oreal's sensitive line of ASB for men.

It has so far worked quite well for me following a straight razor shave, so I just thought I'd mention it in case it helps others. Generally the cream is unscented, although there is a very delicate soapy/creamy note in there that I just can't pinpoint. Nonetheless, worthy of a mere £4-6.
