Identify an accurate statement about moisturizing shampoos.

Moisturizing shampoos are formulated to be gentle and hydrating for the hair, which is why they do not remove as much artificial color compared to regular shampoos. These shampoos typically contain ingredients such as natural oils and humectants that help retain moisture in the hair. This gentle cleansing action is particularly beneficial for color-treated hair, as it helps to maintain the vibrancy of the color by minimizing color stripping during the wash process. In contrast to shampoos high in sulfates, which can be more stripping and may lead to quicker fading of color, moisturizing shampoos are crafted to cleanse without being overly harsh. Additionally, while some shampoos may be marketed to add volume, moisturizing shampoos primarily focus on hydration rather than volume enhancement.
