What type of shampoo cleanses hair with either soft or hard water?

Soapless shampoo is specifically formulated to work effectively with both soft and hard water. This type of shampoo contains synthetic detergents that help to create a lather without relying on traditional soap ingredients that can react with minerals found in hard water. The action of soapless shampoos allows for better cleansing of the hair and scalp without the risk of leaving behind a residue that can occur with soap-based products. This makes them versatile and suitable for various water types, ensuring that the hair is cleansed adequately without interference from mineral deposits that often complicate washing with hard water.

In contrast, clarifying shampoos are designed to remove buildup from products and environmental factors but may not be as effective with hard water. Moisturizing shampoos focus on hydrating the hair and may not address cleansing issues with hard water effectively. Color-depositing shampoos add pigment to hair but are not primarily focused on cleansing and may not be suited to handle the challenges posed by water hardness.
