What are the signs of product buildup in hair?

Dullness and lack of manageability in hair are clear indicators of product buildup. When various styling products, conditioners, and other hair treatments accumulate on the hair over time, they can weigh the hair down, making it appear lifeless and dull. This buildup prevents light from reflecting off the hair strands, resulting in a lack of shine.

Additionally, the hair may become harder to style or manage as the residue from products creates a layer that interferes with styling efforts. Proper cleansing is essential to remove this buildup, restoring the hair's natural shine and making it easier to manage.

In contrast, increased shine and smoothness, ease of styling, and bouncy volume are not associated with product buildup; these qualities typically indicate healthy hair that is free from excessive product residues.
