What Is the Ph of Hard Waterの全貌を丁寧に掘り下げてご紹介します。

You can lower the pH by installing a water softener (which swaps calcium for sodium) or a reverse osmosis system. But honestly? Unless your water’s pH is above 8.5 (which can taste metallic) or below 6.5 (which can leach lead), leave it alone. Your body is a magnificent pH-regulating machine. Your hair, however, might develop a chip on its shoulder and decide to look like straw. That’s not pH—that’s mineral buildup, and it’s a whole different kettle of fish.
