i had a pixie years ago (hair had to be cut off from too much bleaching). it was straight for the most part while short and i used a pomade (american crew at the time, not sure of any CG pomades because i don't use one). it grew out in ringlets and i would use the pomade and it would make the longer hairs curly.
good luck with your big chop if you go for it. it can be really refreshing!
