Is "do" understood as a noun or verb in "hair do"?
Asking this in search of "to make do".
Bonus points if it can be related to German Tolle "tuft [of hair], that thing that Elvis had on his head", itself of obscure origin, surely under influence of toll "wild, great, fun".
En. dole doesn’t seem to be a bad fit, either, as general as its cognates are (portion, piece, divide).
