Define temporary, semipermanent, demipermanent, and permanent color.

Definition should include the characteristics of each category of color. It should also include the following information:

• Temporary hair color makes only a physical change, not a chemical one, in the hair shaft.
• Semipermanent hair color does not require maintenance of new growth.
• Demipermanent hair color creates a tonal change and may make the natural hair color darker.
• Permanent hair color remains in the hair shaft until the new growth of hair occurs.

Process/Skill Questions:

• How is it determined which of the four categories of color the client will receive?
• Why would a temporary hair color be used?
• How long does semipermanent hair color last?
• How long does demipermanent hair color last?
• How long does permanent hair color last?
• What effects do the four different categories of hair color have on the hair shaft?
