How do girls bleach their dark hair on their arms to blonde?
Bleaching is always permanent. Also, depending on how fast your roots grow, it may be between anywhere from 4-8 weeks before there’s a noticable root showing. So you may want to think it through. And if you want to change the color again, it’s more chemicals (aka damage) you’re putting on your hair. The darker your hair is, the longer the process. If it’s done correctly, to go blonde from dark hair, it’s done in stages, and I’m not too sure how long those are, but it is a little on the painful side for some people I hear.
