Study Notes
Patch or Predisposition Test
- Essential for identifying sensitivity to aniline derivative tints.
- Conducted 24 to 48 hours before application of related products.
- Can reveal immediate sensitivity or delayed allergic reactions.
Strand Test
- Evaluates hair reaction to color products.
- Determines processing time and expected final outcome.
- Recommended after patch test but not legally required.
Soap Cap
- Mixture of equal parts permanent haircolor, hydrogen peroxide, and shampoo.
- Application method similar to regular shampoo.
- Utilized to brighten color, reduce unwanted yellow tones in gray hair, and blend lines of demarcation.
Tint Back
- Process of returning hair to its natural or near-natural color.
- Acknowledges increased porosity in previously processed hair may lead to unexpected darker results.
- Filler may be needed for even porosity or color correction.
- Demipermanent haircolor is ideal for this process due to minimal oxidation.
Virgin Application
- Application of color on hair that has not been previously treated.
- Typically involves healthy, undamaged hair.
- Color applied to the entire strand, not just new growth.
Retouch Application
- Addresses noticeable regrowth of hair after coloring, creating a line of demarcation.
- Involves blending new growth with previously colored hair using color or lightener.
- Important for maintaining a uniform hair color.
Single-Process Haircoloring
- One-step process that lightens or deposits color in a single application.
- Includes both virgin tint and tint retouch applications.
- Also referred to as single-application coloring or one-step coloring.
