Touch up your roots and only your roots. "I've seen so many clients who come in because they touched up their roots but accidentally dyed their ends, too," says Ionato. "The ends of your hair are more porous, so they suck up color very quickly." So quickly, in fact, that the runoff from rinsing out your roots can stain them. To avoid this, apply conditioner to your ends right before you rinse out the color at the top of your head. Or you could try this quick tip: Mix about one teaspoon of cornstarch into the dye to prevent it from dripping down through the rest of your hair.
The Hair Color App is a quick and easy way to see what you'd look like with a new hair colour. Before you take the plunge in the salon, try this app to see if you're ready for that major colour change. You just need to upload a photo and outline your hair to create a mask. The outline of your hair is tricky but don't stress, you can tidy up the mask after to be more exact. Then just tap to try new colours. It's super easy to share on social after too to get your friends' opinions.
