Only I’ve never quite managed to master it, which means I end up (resentfully) washing my hair every day, anyway. A 15-minute dry shampoo master class with Charles Worthington’s Marc Trinder last week changed all that for good. Forget wash and go – here’s how to spray and go:

1.    Give the bottle a really good shake.

2.    Hold the can several inches away from you head and spray in short, very fine bursts. Practice a couple in the air first.

3.    Don’t spray the dry shampoo on to your scalp. Aim for the first couple of inches of hair (which, after all, is the bit you want to look non-greasy).

4.    Don’t limit dry shampoo to your fringe and temples. Spray it in concentric circles all around your head, lifting the hair and spraying finely at the roots as you go.

5.    Use a hairdryer on a low speed and heat to gently diffuse the product in to your hair.

6.    Once the dry shampoo’s been in for a minute or so, brush your hair through with a clean brush

7.    Experiment and try using dry shampoo before you go to bed so your hair doesn’t get greasy in the first place (and to save even more time in the morning).

8.    Dry shampoo can be used on clean hair to add guts and volume, and it will help to create bold up-dos – very new season.

9.    To modernise a major up-do and prevent it looking too stiff, place pins randomly to create little dents and dimples in the style.

10.    Keep a bottle of dry shampoo in your bag or desk drawer for touch-ups as required. Balancing Act Dry Shampoo, £4.49, by Charles Worthington, is the perfect size.
