Being rather thin on top helps, no.2 cut and no need for hair products, not even a comb(!) Most hotels have toothpaste and toothbrush in the bathroom amenities kit, or get from the plane.
Antiperspirant is a difficult one. No way around it that I can see other than trying not to sweat (difficult out here!).
Aftershave has gone, I don't like the gels and balms, too sticky out here.
