Study Notes
Demipermanent Hair Colors
- Demipermanent hair colors require mixing with a low-volume developer or activator before application.
- The oxidation process occurs during the mixing with the developer, which influences the resulting color.
- Primarily, demipermanent colors darken natural hair and are available in gel, cream, or liquid forms.
- Contains aniline derivative, necessitating a patch test prior to use to prevent allergic reactions.
- Functions include achieving vivid color results, introducing clients to color services, and blending or covering up to 50% gray hair.
- Useful for refreshing faded permanent color, depositing color without lightening, reversing highlights, and corrective coloring.
Permanent Hair Colors (Oxidation Color)
- Permanent hair colors are mixed with hydrogen peroxide (developer) and provide a long-lasting change in hair color.
- As hair grows, touch-ups are required to maintain a consistent hair color appearance.
- Commonly referred to as tints and composed of ammonia, oxidative tints, and hydrogen peroxide.
- Like demipermanent colors, they also contain aniline derivative, requiring patch or predisposition tests before application.
- Capable of lightening and depositing color in a single process, with a higher alkalinity than demipermanent colors.
- Can lighten hair color, with the lifting ability determined by the pH and concentration of the developer.
- Typically mixed with 20-volume peroxide, allowing for a lift of one or two levels; can lift up to four levels with higher volumes.
- Specific mixing ratios should be followed according to the manufacturer's instructions, with some recommending a 2:1 ratio of developer to hair color.
- The hair cuticle swells upon application, permitting small color molecules to enter the cortex; these molecules oxidize and expand, becoming trapped in the cortex irreversibly.
