Dyeing the underside of your hair can be a fun and simple way to update your look. If you already have light hair, dyeing the underside a darker colour is a great alternative to highlights or lowlights. You can try an extreme tone or a colour just a few shades darker than your own. Whatever you choose, you can be sure you'll have a hairstyle that makes you stand out when you're done.
Select a colour in the same family as your current colour. If the colours are completely different, the style may end up looking more than a little odd. This look works best with similar colours. If you're blond, for example, choose a light brown or auburn for the underside.
Part your hair. Start from the tip of one ear and make your way horizontally across the back of your head in a straight line to the other ear. Secure the front section of your hair high atop your hair, soit does not mix with the bottom part. Wrap the top section of your hair with a shower cap for extra security.
Mix the dye according to the included instructions.
Protect your body from the dye. Wear plastic gloves to keep your hands clean and wrap a towel around your neck.
Apply the dye to your hair. Start in the centre and work your way outwards. Try to avoid your ears, neck and face, as the dye can stain skin for several days.
Wait the recommended amount of time to let the colour settle in.
Rinse the dye out of the bottom section of your hair first to avoid mixing the dye in with your original colour. Condition all of your hair. Dry and style your newly dyed hair normally.
