Study Notes
Permanent Haircolor
- Permanent haircolor contains aniline derivative color molecules and is mixed with a developer, allowing for long-lasting results.
- Available in liquid, cream, and gel forms; used in either single-process or double-process applications.
Single-Process Tints
- Single-process tints enable permanent coloring in one step, applied to dry hair.
- No pre-shampooing, pre-softening, or pre-lightening is needed, saving time and simplifying the process.
- Formulated for use with 20-volume hydrogen peroxide; varying peroxide volumes affect color outcomes.
- Color range varies from deepest black to lightest blond; can lighten or darken hair relative to the client’s natural color.
- Effective in blending gray hair, toning down streaks, and addressing discoloration or faded ends.
Color Selection for Single-Process Tints
- Hair porosity affects color choice; guidelines include:
- Normal porosity: choose half level lighter than desired.
- Slightly porous: select one level lighter.
- Very porous: opt for one to two levels lighter.
- General rules for gray hair:
- To match natural hair and cover gray: select a color close to natural shade.
- To lighten and cover gray: choose a shade lighter than natural.
- To darken hair and cover gray: pick a color darker than natural.
- Incorporate a natural shade when aiming for vibrant color to enhance coverage.
Double-Process Haircoloring
- Consists of initially lightening hair, followed by tinting or toning.
- Hair color harmony may change with age; lighter shades recommended for clients over 40 or 50.
Characteristics of Semipermanent Colors
- No hydrogen peroxide required; self-penetrating colors stain the cuticle and cortex.
- Color typically returns to natural shade after six to eight shampoos with gentle products.
- Requires a patch test due to aniline derivatives; some may need pre-shampooing.
- Follow manufacturer guidelines for best results.
Selecting Semipermanent Color
- Artificial colors mixed with natural pigments darken hair shaft.
- Color chart should represent the natural shade as half the formula.
- Ash or cool shades yield darker results than warm shades, which reflect light and appear shinier.
- For clients with up to 25% gray, choose a shade matching their natural color.
Special Problems and Solutions
- Semipermanent colors may build up with repeated applications; tackle buildup by:
- Applying color solely to new growth.
- Processing until desired shade is achieved, then wet hair and blend for a few minutes before rinsing.
Demipermanent Haircolor
- Considered deposit-only; application procedures mirror those of semipermanent colors.
- Requires mixing with a low-volume developer or activator prior to application.
- Adhere to manufacturer’s guidelines for color selection and processing.
