I heard hard water is bad for my skin? How?

The most common effect of hard water on the skin is causing unnecessary dryness and irritation. This is due to the water's inability to proper dissolve soaps. The unrinsed soap draws out the skin's natural oils leading to skin that is dry, flaky, and itchy. The excess minerals within hard water can also directly dry on the skin which clogs the pores and leads to acne breakouts.
