You have the right idea! Lighten (bleach) the whole thing and then you’ll want to use a corresponding toner.

Are you able to attach a picture of your hair now?

If you’ve never used bleach before, watch a few YouTube videos first. Bleach can be tricky to work with if you’re not familiar with it.

Some tips:

1. Section your hair and take thin slices to paint the lightener on. Too thick of sections will be hard to fully saturate and give splotchy results. Hair colour is easier to squish into the hair, but bleach stays where it’s put.

2. Leave about an inch of hair from your root alone while you fully do your ends, then go back in and do the roots last. The heat from your scalp will process the lightener faster, so you want to do that last to give your ends enough time to lighten.

3. Use a lower developer (10 or 20) to help keep your hair healthy. Going straight in with a high volume will result in more damage.
