My water is city water. We are known to have some of the best water in the state. It isn’t hard water. It’s relatively soft. When I shower, it leaves a build up on my hair that is sticky and makes it very hard to brush. Looks like I haven’t showered in a month right after I dry my hair. What’s strange is that my next door neighbor has the same water as me and doesn’t have this issue. I know this because lately I’ve been washing my hair at their house with no issues. I’ve had multiple plumbers come out and the haven’t been able to solve the issue. Has anyone experienced this?
