I live in the country, and our water is very hard. Whenever I get my hair dyed, it always fades because of our water. Is there any shampoos, conditioners, or product I can use that will make my hair color last longer and not be damaged from the water? I've heard of little packets of stuff you put in your shampoo that takes out the minerals in the water, but I don't know what it's called or where to get it. Any help would be greatly appreciated!
