What can be a consequence of using too much conditioner on hair?

Using too much conditioner on hair can lead to it becoming greasy and heavy. Conditioners are formulated to add moisture, smoothness, and shine to hair, but when applied in excessive amounts, they can weigh the hair down. This happens because conditioners often contain oils and emollients that, while beneficial in moderation, can create a buildup when overused. This buildup can leave hair looking limp, dull, and greasy, rather than clean and voluminous. In contrast, moderate use of conditioner is intended to enhance hair health and manageability without causing unwanted heaviness.

The other choices involve effects that are not typically associated with excessive conditioner use. For instance, while conditioners can sometimes enhance the appearance of hair color or help manage frizz, these are primarily beneficial properties when used appropriately. Over-conditioning, however, detracts from these benefits by leaving the hair weighed down.
