Not ready for a full softener? Try a shower head filter. These little gadgets screw onto your existing setup and use carbon and KDF media to catch minerals. They won’t soften the water entirely, but they’ll reduce the scale on your skin and hair. It’s like a spa day lite.
Another option: magnetic or electronic descalers. These clamp onto your main pipe and send an electric pulse to change the mineral structure so they don’t stick. Skeptical? Me too. The science is shaky, but some swear by them. If you’re on a budget, it’s a fun experiment.
