What characterizes oxidative color?

Temporary change
Semi-permanent color
Demi-permanent and permanent color
Physical change only

The correct answer is: Demi-permanent and permanent color

Oxidative color is characterized by the use of a developer, which causes the color molecules to penetrate into the hair shaft. This results in a lasting and permanent change in hair color. Options A and B, temporary and semi-permanent color, do not involve a developer and only coat the hair externally, resulting in a temporary change. Option D, physical change only, does not involve any chemical reaction and will not result in a lasting color change. Demi-permanent and permanent color, option C, are the only options that involve a chemical reaction and result in a long-lasting change in hair color.
