Going out to play with sun-kissed highlights in your hair? If you want to prevent them from turning into the colours of the rainbow (been there, done that!), here’s a simple trick. Coat your strands with a hard-working hair oil like argan or coconut that creates a protective slip, prevents staining and allows the colour to come off easily. Don’t forget to double up on the moisture after you play with a leave-in mask that allows your hair stay hydrated for longer.
