Trying to find for the right shampoo for hard water? You might not need to look any further than your basket of baby bath supplies.

Cocamidpropyl betaine is a detergent often found in baby shampoos or added to other sulfate-free shampoos to boost foaming. It is a mild cleanser that works better than other detergents in hard water—because it is neither cationic nor anionic. It can act as either—so the minerals in hard water do not prevent it from creating foam or alter its ability to clean.

The mildness of these shampoos depends on how often you wash your hair as well as the formulation of the product. If a shampoo seems too harsh, try it diluted first before you rule it out for good.
