You probably already know about using dry shampoo to disguise oiliness when you don’t have time to wash your hair (Scharzkopf Batiste is one of the best known and easiest to get hold of). But if you don't have any to hand use baby powder instead, sprinkled only onto areas where there's obvious oiliness. Hair will look dull and grey if the powder's sprinkled everywhere. The roots are usually the worst affected so make sure you massage the powder right into the hair – to combat dulling and to give lank hair a bit of oomph.
