Normally the pressure of your hands pushing down can cause the paint to smudge no matter how dry you think it is, this is why I don't re-paint the whole head before re-rooting, I would paint the strip where the hair goes and then re-root and stick the head back on to the body and paint the rest of the head.
It looks like your going to have to remove the paint and start again, next time try my method, it should work out for you
