That white crust is what meets your skin every morning.
Swiss tap water carries high levels of calcium and magnesium. You can see what it leaves on your nozzles. The same mineral load settles on your skin and coats your hair every time you shower, which is why shampoo lathers less, conditioner sits on the surface instead of soaking in, and skin feels tight once it dries. If it does that to metal, imagine what it does to your hair.
