Before you buy your colour, always check the box to make sure the shade will give you the result you’re looking for. There are pictures on the side of the box with before and after results. Match the shade at your roots (not your ends) to the “before” picture and you can expect a colour result shown on the after side. Another pro tip? Once you colour your hair, another box of hair dye will not lighten your hair without bleach, so make sure you’re committed to that Black or Dark Brown before you take the plunge! If you’re debating between two shades, it may be best to try the one that is slightly lighter so that if you do decide you want to go darker, you can reapply later.
