Does developer have bleach in it? No. Does your friendly neighborhood software developer have bleach in them? Also no, unless they’ve been on a bender. The confusion is real, but the science is simple: developer is a helper, not a doer. Bleach is the destroyer of pigments, bad dye jobs, and questionable life choices.
So next time someone asks you this question, you can confidently say, “Friend, that’s like asking if a paintbrush has paint in it. No, but it’s about to get messy.” Then sip your coffee, stay away from 40 volume developer, and never, ever joke about swapping bottles with your hairdresser. They will cut you. Not your hair. You. With scissors. And that hurts.
