Study Notes
Characteristics of Haircolor Classifications
-
Temporary Hair Color
- Consists of large dye molecules
- Has an acidic pH
- Involves a physical reaction
- Lasts until removed by shampooing
- Deposits color on the outside of the cuticle
- Not mixed with hydrogen peroxide
- Requires a predisposition test if containing aniline derivative
-
Semipermanent Hair Color
- Contains medium-sized dye molecules
- Slightly alkaline pH level
- Combines chemical and physical reactions
- Gradually fades over time
- Deposits and slightly penetrates the cortex
- Does not require mixing with hydrogen peroxide
- May require a predisposition test if it contains aniline derivative
-
Demipermanent Hair Color
- Features medium-small dye molecules
- Exhibits a moderately alkaline pH
- Involves both chemical and physical reactions
- Experiences some fading, potentially leaving a line of demarcation
- Provides no-lift color that deposits and slightly penetrates the cortex
- Mixed with hydrogen peroxide for activation
- May require a predisposition test if it contains aniline derivative
-
Permanent Hair Color
- Comprises small dye molecules
- Alkaline pH level is present
- Engages in chemical and physical reactions
- Lasts permanently after application
- Lifts (lightens) hair and deposits color into the cortex
- Requires mixing with hydrogen peroxide
- Necessity for a predisposition test is determined based on the presence of aniline derivative
