Color-treated hair refers to hair that has undergone a chemical process to change its natural color. This can involve permanent, semi-permanent, or temporary hair dyes, which can enhance or alter the hair's appearance. Common reasons for coloring hair include covering gray strands, trying a new look, or adding highlights for dimension. Maintaining color-treated hair requires special care to preserve its vibrancy and health. Products designed for color-treated hair, such as sulfate-free shampoos and conditioners, help prevent fading. Regular deep conditioning treatments can also nourish the hair, keeping it soft and manageable while minimizing damage from the coloring process.
