No, a toner is not permanent. Toners are typically demi-permanent, meaning they are less damaging and fade gradually over time. Unlike permanent hair dyes which lift and alter the hair's natural pigment, toners primarily work by depositing color onto the hair shaft, correcting unwanted tones or enhancing existing color.
Understanding Toner vs. Permanent Dye
Several key differences distinguish toners from permanent dyes:
-
Permanence: Permanent hair dyes permanently alter the hair's pigment, leading to lasting color changes. Toners, on the other hand, are demi-permanent, offering a temporary color correction or enhancement. Their effects fade gradually with washing.
-
Ammonia Content: The ammonia content varies between toners. Some, like hair glazes, sit on top of the hair, while others bind more deeply but still aren't considered permanent. This is in contrast to permanent dyes which typically contain a higher ammonia concentration to lift and deposit color effectively.
-
Developer: Permanent dyes require a developer (like peroxide) to lift the hair's cuticle and deposit color. Toners, being demi-permanent, do not require a developer or have a significantly lower concentration. They deposit color without significantly altering the hair's natural pigment.
-
Process: A toner is a process, not a product, as frequently it utilizes demi-permanent color.
-
Examples: Wella Color Charm offers a "Permanent Liquid Toner," but the term “permanent” here is used in a somewhat different way, suggesting a longevity that's greater than other demi-permanent products. It still does not achieve the permanence of a true permanent hair dye.
While some toners might last longer than others, ultimately, they are designed to fade gradually, minimizing potential damage to the hair. The fading rate depends on factors like washing frequency and product quality.
