This touch-up spray is great for people with permanent or semi-permanent dyed hair. It's a quick and easy way to fix your roots between colouring at home and salon appointments.

The spray gives you a natural-looking finish and covers roots well. It hides grey roots and turns them back to your original colour. It comes in 10 shades, from blonde to black.

To use, shake the can well and spray it onto dry, clean hair. Hold the can about 13 cm away and spray lightly to get the best results.

This lightweight formula stays in place when you brush and comb your hair, and you can wash it out with regular shampoo. The 75ml bottle is travel-sized and should last for up to 25 uses.

You get one 75ml L'Oréal Magic Retouch Instant Root Concealer Spray in Dark Brown colour.
