    TLDR Gray hair requires special coloring techniques and care to maintain quality and strength.
    This study addresses the challenges faced by hairdressers and colorists in managing gray hair, focusing on the biological and structural changes that occur with depigmentation. By analyzing scientific literature on hair biology, oxidative stress, and melanogenesis, the research highlights the differences between gray and pigmented hair in terms of follicular activity, oxidative balance, and fiber structure. These differences necessitate adapted coloring techniques and targeted care strategies to maintain hair fiber quality. The study provides an evidence-based framework to improve coloring outcomes and support hair strength, helping professionals make informed cosmetic and care decisions for clients with gray hair.
