What type of haircolor creates a chemical change to provide longer-lasting results?

Oxidative haircolor is known for producing a chemical change that results in longer-lasting color. This type of haircolor works by containing ingredients that require an activator, typically hydrogen peroxide, which allows the color molecules to penetrate the hair shaft and chemically bond with the hair.

When oxidative haircolor is applied, it interacts with the natural melanin in the hair and the developer to create new, larger color molecules that remain in the hair. This process leads to a more permanent and durable color outcome compared to other types of haircolor, which often do not result in such a lasting change.

In contrast, other types of haircolor such as non-oxidative, demi-permanent, and temporary haircolor do not undergo the same level of chemical change. Non-oxidative haircolors primarily coat the hair rather than penetrate it, while demi-permanent colors can provide some lasting results but do not create a permanent change in the hair structure. Temporary haircolors are designed for brief use and wash out easily, making them unsuitable for longer-lasting results.

This understanding of oxidative haircolor is crucial for anyone working in haircoloring, as it allows them to choose the right product based on the desired outcome for their clients.
