You wouldn’t buy shoes without knowing your size, right? Same here. Grab a simple water test kit from a hardware store or send a sample to a lab. It’ll tell you how hard your water is on a scale from “meh” to “yikes.” Most homes fall between 7 and 15 grains per gallon, but if you’re above that, you’ll need a bigger system.
Funny story: my friend Sarah tested her water and found it was harder than a week-old bagel. She’d been blaming her shampoo for her frizzy hair, but it was the water all along. Knowledge is power, and in this case, it’s also fluffy hair.
