Question: 1 / 400

What is the difference between demi-permanent and permanent hair color?

Demi-permanent colors do not lift

Demi-permanent hair color is designed to deposit color but does not contain the necessary ingredients to lift the natural pigment of the hair, which is why it does not lighten the hair. This type of hair color usually lasts between 20 to 28 shampoos, making it ideal for enhancing color or covering gray without the commitment of a permanent change.

In contrast, permanent hair color contains a developer that allows it to penetrate the hair shaft and lift the natural pigmentation, resulting in longer-lasting results. As a result, while demi-permanent formulas are great for subtle changes and enhancements, permanent color is the choice for those looking to achieve a more dramatic or long-lasting color transformation.

Understanding this distinction is key in hair coloring practices, particularly in choosing the right product based on a client's needs regarding color longevity and desired results.
