Dry shampoo is without-a-doubt one of the handiest products in the beauty game.
Whether you're heading somewhere in a rush, you've just come from the gym, or you simply can't be bothered washing your hair, dry shampoo is an easy win to get that niggly grease to go away.
But recently celebrity chief Nigella Lawson has said that most of us have been using dry shampoo wrong this whole time.
In a new column for the UK newspaper the Sunday Times, Lawson revealed putting dry shampoo in your hair before you go to bed is the way to go.
Blast yourself with it before you go to bed and when you wake up in the morning, it will have disappeared, taking the grime and grease with it.
We can't be the only ones that have never thought of this!?
