Q. I HAVE NATURALLY STRAIGHT HAIR. HOW DO I INJECT LASTING VOLUME INTO IT FOR MY BIG DAY? Maisie, 27 Joanna: I’d suggest setting your hair the night before – use a good mousse and pop some rollers in before bed. If this is too difficult for you to do yourself, you could always get your hair blow-dried the night before and ask your stylist to do your rollers. Then, on the morning of your wedding, simply use a texture spray for a last boost of fabulous volume.
