My wife and I just bought a house with spring water from a house with town water. Ever since we moved in, after she showers, her hair feels greasy and knotted up when we run our fingers through it. Also our skin feels kind of sticky after we get out of the shower and are drying off. Is spring water soft or hard? Should I get a home filtration system or water softer system? Is this even a plumber question? I need to do something. She's gone an hour to her parent's house to shower because her hair is so heavy and greasy feeling. Please help! Thank you!
