Skin disorders like eczema, psoriasis, dandruff and chronic dryness are all heavily effected by the moisture content of the skin. 
Showering and bathing in chlorinated tap water robs skin and hair of their natural protective oils, causing scaling, itching and bacteria imbalances. Chlorine is a strong oxidant and causes damage to skin and hair even at very low levels. Most tap water maintains a residual chlorine level greater than is recommended for swimming pools, 1.5 ppm.
Chlorine also kills much of the beneficial bacteria on the surface of the skin that offers a natural defense against skin disorders.
By removing chlorine with a shower water—where most of the exposure to chlorine occurs—and keeping our bodies hydrated properly, we allow our body’s natural healing mechanisms to work properly. In many cases shower filtration can help prevent and cure skin disorders. As with most health problems, prevention is usually more effective than treatment.
