"Color-treated" refers to hair that has undergone a chemical process to change its natural color. This can involve dyeing the hair with permanent, semi-permanent, or temporary hair color products. The process can enhance or alter the hair's appearance, allowing individuals to express their style or cover gray hair. Maintaining color-treated hair often requires special care to preserve the vibrancy and health of the hair. Products specifically designed for color-treated hair typically contain ingredients that help protect against fading and damage. Regular conditioning and minimizing heat exposure are also recommended to keep the hair looking its best.
