Iron, a mineral found in well water, is often at high enough levels that the water stains everything it touches like a vat of spilled ink. This includes your lovely locks. That's right -- if your hair is light brown or lighter, it will soon take on an icky orange cast from the iron. Forget a quick fix, lady. Face it -- your mane is stained. If you can't see the orange in your hair because it's dark-colored, don't think you don't have a problem. Instead, run your fingers through your tresses. Do your strands have that coarse, crunchy feeling? If you answered yes, you have mineral build-up. Keep your cool -- you can reverse the process and get back to your natural hair.
