A pH balanced shampoo is specifically formulated to match the natural pH level of the hair and scalp, which typically ranges from 4.5 to 5.5. The primary goal of using such a shampoo is to maintain the hair's natural moisture. This balance is crucial because hair that is too alkaline (higher pH) can become dry, frizzy, and more prone to damage, while hair that is too acidic can be overly brittle. By keeping the hair’s pH balanced, the shampoo helps to preserve the moisture content, make the hair healthier, and support its overall integrity.

Other options touch on benefits that may not be directly correlated with the primary function of a pH balanced shampoo. While making hair shinier may be a secondary effect of maintaining moisture, it is not the main purpose. Deep cleansing can be achieved with cleansing shampoos that may not necessarily be pH balanced, and neutralizing hair color is not related to moisture retention but rather targets issues with color treatment products. Thus, the maintenance of natural moisture levels stands out as the most relevant and desired result of a pH balanced shampoo.
