Study Notes
Permanent Haircolor Overview
- Permanent haircolor products have an alkaline nature, typically with a pH range of 9.0 to 10.5.
- Upon processing, hair is shampooed, and as it dries, it returns to its normal pH, causing the cortex to shrink and cuticle to close, trapping color molecules.
- Permanent haircolor does not wash out during shampooing, though it may fade over time and require refreshing.
- New hair growth creates a line of demarcation between previously colored and new hair, necessitating a retouch application.
Gray Hair Coverage
- Permanent haircolor is the preferred choice for effectively covering gray hair.
- It works by diffusing natural pigment through lifting and adding artificial color, resulting in a uniform blend of gray and non-gray areas.
Types of Permanent Haircolor
- Oxidation Tints: Known as aniline derivative tints or synthetic-organic tints, these can lighten and deposit color simultaneously and are available in a wide range of colors.
- Toners: A subset of oxidation tints, toners are aniline derivatives with pale shades intended for use on pre-lightened hair.
- Predisposition Test: Most oxidation tints necessitate a patch test before application to check for allergic reactions.
- Compatibility: When hair is healthy, oxidation tints can be safely used with other chemical services like waves and relaxers.
- Form of Application: Oxidation tints come in bottles, tubes, or canisters in semiliquid or cream forms and must be mixed with hydrogen peroxide to activate the oxidation reaction.
