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.
