I have really dry hands . It's mostly that my skin doesn't like the really hard water here. I try not getting them wet too much, but with a babe in diapers I can't avoid it enough. Sometimes the backs of my knuckles split and bleed because it is so dry. Even the commercial handcreams aren't always very useful. Weleda Calendula ointment was good, but really expensive. Is there something simple I can make myself for it? - I've read a bit about shea butter, would that be enough on it's own?
