What could be the consequence of overlapping color applications?

Overlapping color applications can lead to potential hair damage and uneven color. When color is applied onto previously colored hair, it can result in excessive buildup of the dye, particularly if the overlapping occurs frequently. This area can absorb more color due to the existing color already present, leading to darker patches or uneven results. Moreover, the additional processing can weaken the hair structure, contributing to damage such as dryness and brittleness. Understanding this consequence is crucial for maintaining hair health and achieving a uniform color result. Proper technique should be emphasized to avoid such issues and ensure even color application without compromising hair integrity.
