Yes, you read that right. Dawn dish soap is your new best friend. It’s a degreaser, so it strips away buildup—including that purple pigment clinging to your hair cuticles like a stubborn toddler. I’m not kidding; this is the nuclear option, and it works fast.
Wet your hair completely. Squirt a generous amount of Dawn (the blue kind is classic, but any will do) directly onto your strands. Don’t be shy—we’re not trying to be gentle here. Lather it up like you’re washing a greasy casserole dish.
Rinse thoroughly, then repeat. You’ll likely see the water run a scary shade of purple, which is a great sign. Wash it two or three times until you see the purple fading into a pastel memory. Your hair will feel a bit straw-like afterward, but that’s okay—we’ll fix that soon.
