How to apply: Preparations
While this ammonia-free formula is suitable for sensitive skin and hair, it is still possible that you might get an allergic reaction. That is why you should always do an allergy test before colouring your hair at home - even if you have coloured your hair before! To do so, simply press a small amount of colourant somewhere on your skin, such as behind the ear. Go about your day; if the spot where you put your colourant still looks fine after 24 hours, you can go on with colouring!
