Last month we talked about swapping out your current shower-head for one that filters to fix dull and brassy looking hair caused by chemicals and hard water.
But, if you’re not inclined to replace your shower head just yet, try using a clarifying shampoo, like Bumble and Bumble Sunday Shampoo, to fix past hard water damage. It’s named “Sunday shampoo” because you should only use it once per week. It will remove build-up on your hair, but it’s too strong for most people to use every day.
Keep in mind that some clarifying shampoos aren't meant for color-treated hair, though some are recommended to use as a pre-coloring shampoo treatment.
