Which two types of hair color are considered nonoxidizing?

The correct answer identifies temporary and semipermanent hair colors as nonoxidizing types. Nonoxidizing hair colors do not require the use of hydrogen peroxide or other oxidizing agents to develop their color.

Temporary hair color is designed to coat the hair shaft and typically washes out after one or two shampoos. It does not penetrate the hair's cuticle, making it a non-permanent option that is easy to apply and remove.

Semipermanent hair color, while lasting longer than temporary options, also does not contain harsh chemicals or oxidizers. Instead, it tends to absorb into the hair shaft, providing more vibrant results that can last several weeks but eventually fade with washing.

In contrast, other options involve processes that either penetrate the hair more deeply or require oxidizing processes, which would not classify them as nonoxidizing. Recognizing the differences in how these products work is essential for selecting the appropriate hair color that aligns with a client's desires and needs.
