*Lasi tondi* strikes me as a little old fashioned, but it is not unheard of.

- Vole nevole Trebinto lasas fortondi sian belan barbon

*Tondigi* is of course also possible. Actually, all your suggestions sound reasonable and I would notice anything strange about them in context. To your list I would also add ***Ĉu vi havas novan hararanĝon?*** It's what they used in *Esperanto Pasporto al la Tuta Mondo*
