Minerals in water can cause brassiness in blonds and redheads. If your hair is showing a brassy tinge, don’t despair. Below are the few ways to eliminate the problem:
1. Mix 1/4 cup of distilled white vinegar with 1 cup of filtered water and rinse your hair after you condition. If you don’t have filtered water use a mineral water from the supermarket. Rinse your hair with cool water.
2.Use a specially formulated blue-based shampoo on a weekly bases. Designed to work like a violet or blue toner, these shampoos adjust the hair color to prevent unwanted orange tones. This will lessen the chance that brassy tones will become noticeable.
3. Install a water filter to the shower nozzle if your water is iron rich, or a water softener, to remove the excess iron in your water.
If brassiness persists after repeated attempts to remove it, seek help from a professional hair colorist.
