Repeat until you've done all of your hair. I added the pink color 2/3 of the way up the blonde part (where I just bleached.) You could just color your tips if you wanted. I left it on for 35 minutes which is what the instructions said to do. Well... if you wanted the color to stay in longer than a week or two. Then I washed it and THEN. I. HAD. PINK. HAIR!
Now I kind of want purple streaks in my hair. Her base color is pretty much my exact color already, so it would just be a matter of doing the streaks, right? I have no idea. I have never even had highlights done. Zero hair coloring experience, here.
