I bleached my hair today with 20 vol for 20 minutes and while some of it looks great, I also missed several spots. Can I just go over what I missed again? I don't want to severally damage my hair but I also don't want to go around looking like a spotty hot mess.
Any advice would be appreciated!
Going over the spots you've missed should be fine, as long as they haven't been processed at all within the last month. If they haven't then touch up the patches, making sure to avoid the areas you've currently already bleached.
Great, thanks!
