What if you use too much conditioner?

If you use too much conditioner, your hair can become heavy and lifeless. This happens because the ingredients in conditioner, such as oils and moisturizers, can build up on the hair. This may cause your hair to become greasy more quickly and harder to style. Washing your hair regularly with a mild shampoo helps prevent this buildup.

Since this is a general question about the use of conditioner, no specific product advice applies.
