I know you want to nuke that purple away, but super hot water can damage your hair and make the color residue sink deeper. Use warm water—comfortably warm, not the temperature of a witch’s cauldron. It opens the cuticles just enough to let the dish soap do its job without frying your scalp.
How to Get Purple Shampoo Out of Hair? (Even when it stains your hair
Another pro tip: Use a clarifying shampoo instead of dish soap if you have a sensitive scalp. Products like Neutrogena Anti-Residue Shampoo exist for exactly this kind of drama. Lather, rinse, repeat until the purple vibes are gone.
Don’t Forget the Vitamin C Hack
If dish soap isn’t enough, let’s get clinical. Crush up a few Vitamin C tablets (the cheap, plain kind from the pharmacy) into a fine powder. Mix that powder with your regular shampoo to create a gritty, fizzy paste. Apply it to your damp hair and let it sit for about 10 minutes. The acidity helps break down the purple pigment—it’s basically science saving your hair from a fashion faux pas.
Rinse it out, and be ready to be amazed. Your hair will smell faintly of citrus and victory. If you don’t have tablets, a squeeze of fresh lemon juice mixed with shampoo works in a pinch—just rinse thoroughly to avoid sun damage later.
