Semi-permanent hair dye is the correct choice for providing temporary color. This type of dye is designed to coat the hair shaft without penetrating the hair cuticle, which means that it gradually washes out over time, usually lasting between 4 to 12 shampoos. Additionally, semi-permanent dyes do not contain ammonia or require a developer, making them less harsh on the hair compared to permanent dyes. Because they don’t change the natural hair color significantly and fade with each wash, they are ideal for those looking to experiment with color temporarily.

Permanent hair dye, on the other hand, is formulated to create a long-lasting change in hair color by penetrating the hair shaft and altering the natural pigment. Highlights refer to lighter strands created in the hair using various techniques, and while they can be temporary based on the products used, they are typically meant to provide a more permanent change in color. Bleaching agents are used to lighten the hair and do not provide color but instead remove the natural pigment, leading to a lightened effect. Thus, semi-permanent hair dye stands out as the ideal choice for those seeking a temporary color option.
