Question: 1 / 400

Which type of hair color provides the longest lasting results?

Temporary hair color

Semi-permanent hair color

Demipermanent hair color

Permanent hair color

Permanent hair color is designed to provide the longest lasting results because it contains a chemical process that allows the dye to penetrate the hair shaft deeply. Unlike temporary or semi-permanent colors, which coat the hair and fade with each wash, permanent color alters the hair's structure by lifting the cuticle and introducing pigments into the cortex. This process results in a more enduring change in the hair color that can last for several weeks to months, depending on hair type and care. Additionally, permanent hair color often contains an alkaline ingredient that ensures the color binds effectively, further enhancing its longevity. This makes it the ideal choice for those seeking a substantial and lasting change to their hair color.
