Prom hair. Should I wash my hair the night before?

I have my prom tomorrow. For my hair I am not doing an updo, rather I want my hair down and straight, but pinned at the back.





I know for updo's, you generally wash your hair the night before. Is this the same for straightening it? Or will they wash and blow dry tomorrow?





I figure there's no point in washing it tonight, if they're just going to wash it tomorrow morning...





Thanks!Prom hair. Should I wash my hair the night before?
it should be fine if the wash and dry it in the morning. generally the wash and dry is for extensive up-do's in a limited amount of time. generally a bride rushing to her wedding
