How does the hair's thickness influence the coloring process?

Thicker hair may require more time for the color to develop due to its denser structure and the additional layers of cuticle that color molecules must penetrate. The thickness of the hair can affect how the hair absorbs the color and how long it takes for the dye to fully process. Thicker hair typically has a longer reaction time because the formulation has to work through more layers to ensure even color distribution and optimal results. This means that stylists often need to adjust processing times based on the hair's thickness to achieve the desired shade effectively. Therefore, understanding the influence of hair thickness on development time is crucial for a successful coloring process.
