Question: how many times in one day can you bleach your hair?
Answer: You'll have to do one step at a time. And with each bleaching, you'll lighten your hair up to three tones. So, you will have to bleach your hair to get to the tone that you want but you can't do it twice in a row. Bleaching your hair twice in a row, whether it's the same day or the next day, can cause breakage.
