Pick an eye shadow that best matches your hair colour, blend it into your roots and, once the unwanted colour has been covered, hold it in place with hairspray.
If you frequently struggle to keep up with your hair appointments, you may want to invest in a hair colour powder. My absolute favourite is the Bumble & Bumble Hair Powder 125ml (£28.00 Selfridges / $36.00 Sephora). It is available in blonde, brown and black and it covers a multitude of colour sins. It is also a hero for fine-haired girls, as the colour & texture gives the illusion of more hair and the formula creates great volume that stays put.
