Newbie. Home bleaching
Hello :) My 61-year old sister has short, thinnish hair. Periodically she spends $80 having it lightened, cringing every time. How much happier she'd be could most of those monies go to animal rescue! Is one able to safely bleach the roots at home, and if so, which product(s) are best and safest? I dye and refresh my own roots periodically but use L'Oreal Preference . . . which, surely, is different from bleaching -- right? Thanks!
