Hair is made of protein, specifically keratin. Bleach uses peroxide to break those protein bonds and remove melanin (your color).
Imagine your hair as a sturdy rope. Bleach starts snipping away at the individual threads. The more you snip, the weaker the rope gets.
That’s why over-bleached hair feels like cotton candy after a rainstorm. It stretches, snaps, and looks like it’s crying for help.
Good Damage vs. Bad Damage? (Yes, That’s a Thing)
Here’s the twist: controlled damage can be manageable. Think of a professional balayage or a subtle ombre. That’s like a tiny paper cut—annoying but healable.
Bad damage is when you bleach already-damaged hair. Or when you leave it on for an hour because “more time = more lift.” Spoiler: it doesn’t.
Bad damage breaks your hair. Not just dries it out. I mean actual breakage, like tiny hairs snapping off mid-strand. You’ll find little stubs on your pillow. It’s sad.
