Highly concentrated hair dye is designed to dramatically change hair's natural color. This dye is especially damaging to the skin and hair if it's left on for too long, so it's important to ensure you remove all traces of dye from your hair and scalp. Darkly pigmented dyes that are left on for too long might temporarily alter the color of the scalp and the skin around the hairline.
Rinse the hair thoroughly by standing in the shower with your head tilted slightly backward. This ensures that the dye runs away from your face and eyes. Allow the water to run over your head for two to three minutes.
Use the detachable shower head to spray water directly onto your hair. Use the massage setting or the setting that produces the most forceful water. Starting at the hairline, put the shower head up against your hair while tilting your head backward. Move the shower head downward, rinsing until you've reached the ends of your hair.
Remove hair dye stains using baking soda or toothpaste. Apply a pinch of baking soda to the affected area and gently rub. Allow the baking soda to remain on the skin for one to two minutes; then rub it off using a warm washcloth. Repeat until the stain is gone. Toothpaste containing baking soda is also an effective hair dye remover, using the same steps.
