Study Notes
Hair Coloring Overview
- Mixed tint products must be used immediately after combining.
Permanent Haircolor
- Permanent haircolor is alkaline, with a pH between 9.0 and 10.5.
- After processing, hair is shampooed and dries, returning to its normal pH, causing the cortex to shrink and the cuticle to close.
- Permanent color does not wash out; fading may occur over time, necessitating refreshers.
- New growth creates a line of demarcation, requiring a touch-up application for the colored roots.
- Considered the best option for covering gray hair, it diffuses natural pigment and adds artificial color, allowing gray and non-gray hair to blend seamlessly.
Types of Permanent Haircolor
-
Oxidation Tints:
- Also known as aniline derivative tints, they can both lighten and deposit color simultaneously.
- Available in a diverse range of colors.
- Include toners designed for pre-lightened hair, typically in pale shades.
- Require a predisposition (patch) test due to the presence of aniline derivatives.
- Compatible with other professional chemical services, assuming hair is healthy.
- Available in semiliquid or cream forms, packaged in bottles, canisters, or tubes.
- Must be mixed with hydrogen peroxide to activate the oxidation reaction, starting the coloring process.
