Every week, Sali Hughes addresses a beauty topic in Weekend magazine and accompanies it with a "how to" video. And each week readers queue up to ask her advice on everything from bleeding lipstick (not as dramatic as it sounds) to haircare (or hair removal). Tomorrow lunchtime, Sali will be with us for two hours to answer your questions. So get thinking about what you've always wanted to know. We'll keep this thread open for an hour, and then kick off tomorrow on guardian.co.uk/fashion tomorrow from midday.
