What is the main function of hair fillers?

The main function of hair fillers is to increase volume. Hair fillers are designed to add density and fullness to the hair, making it appear thicker and more voluminous. This is essential for clients looking to enhance their hairstyle by giving the appearance of more body and lift. Fillers work by adhering to the hair strands and creating a plumping effect, which can be particularly beneficial for those with fine or thinning hair.

Although hair fillers can have other benefits such as improving the overall look of the hair, their primary purpose revolves around volume enhancement, rather than color absorption, shine, or simply coating the hair shaft. Thus, seeking hair fillers primarily focuses on volumizing and enhancing the hair’s presence on the head.
