Nice guess! You're correct, long hair, curly hair, and curly long hair will be in the next update (just finished writing long hair today actually).
Sorry, right now there isn't much to do after learning magic. That is kind of the second-to-last stage of the game, the next release will probably be the endings and wrap of the game. (Though there is a chance I'll split it into two more releases if it's taking too long)
