What is the effect of too much product buildup on hair?

When there is too much product buildup on the hair, it results in a weighed-down and dull appearance. This build-up can occur from the regular use of styling products like gels, mousses, and sprays, as well as from shampoos and conditioners that may contain heavy ingredients. As these products accumulate, they can prevent moisture and nutrients from penetrating the hair shaft effectively. Instead of feeling light and bouncy, hair becomes heavy and loses its natural luster. This can lead to a lack of volume and an overall flat look, which is why the correct answer highlights that excessive buildup can make hair appear dull and weighed down. Additionally, product buildup can contribute to other issues, such as scalp irritation or in some cases, even hair breakage, further emphasizing the importance of using the right amount of products and maintaining a proper cleansing routine.
