What is a common sign of product buildup on the hair?

A common sign of product buildup on hair is flat and lifeless hair. This occurs because excessive application of styling products, conditioners, or shampoos can leave a residue that coats the hair strands. As a result, the hair can lose its natural movement and volume, appearing weighed down and dull.

Product buildup obstructs natural light reflection, which contributes to the lifeless appearance. It can also hinder the effectiveness of other hair care products, resulting in an ongoing cycle of using more products to achieve desired results, exacerbating the buildup issue.

In contrast, shiny hair, enhanced volume, and bright color are typically indicators of healthy hair that is well-maintained and free from heavy product accumulation.
