What are the two types of oxidizing hair color?

The two types of oxidizing hair color include demi-permanent and permanent hair color. Demi-permanent hair color contains low levels of peroxide and is designed to deposit color without lifting the natural hair color. This type of color typically lasts longer than semi-permanent options, usually around 20 to 28 shampoos, as it allows for a mild chemical reaction that helps the color bond to the hair.

On the other hand, permanent hair color involves a higher concentration of oxidizing agents, such as hydrogen peroxide, which not only deposits color but also lifts the natural pigment in the hair. This means that permanent color can change the hair's natural color significantly and lasts until the hair grows out or is cut. Thus, both demi-permanent and permanent colors utilize oxidizing agents to achieve the desired results, making them the two primary types of oxidizing hair color.

In contrast, other options introduce concepts like temporary color, which does not involve oxidation and washes out easily, or mention non-oxidizing color, which lacks the chemical reaction necessary for permanent changes. Therefore, focusing on the types that use oxidizing processes clarifies the correct choice.
