What if I didn't get my hair as light as I wanted it in one bleach session? Can I bleach it again?

Repeated bleaching is not recommended since you’re putting yourself at risk of overprocessing and breakage. If you do bleach again, make sure to wait 3 weeks to give your hair cuticle enough time to heal, close and lay flat again. If you want to achieve a platinum blonde from dark hair, you will most likely need to get to a mid-toned orange color first, then condition and care for your hair before you bleach it again. Once you have achieved the level of lightness about the inside of the banana, you can apply a toner to help get you to the platinum level. This is a long process with many steps, and can’t be rushed if you want to preserve the integrity of your hair! Always consult a professional and do your research before beginning this process.
