Study Notes
Permanent Haircolor Overview
- Permanent haircolor products are alkaline, with a pH range of 9.0 to 10.5.
- After application, hair is washed and dries, returning to its normal pH, causing the cortex to shrink and cuticle to close, trapping color molecules.
- Permanent haircolor does not wash out during shampooing; however, it may fade over time and require refreshing.
- New hair growth creates a line of demarcation, necessitating a retouch application of permanent haircolor to blend new growth with previously colored hair.
- Considered the best option for gray hair coverage, permanent haircolor diffuses natural pigments and adds artificial color for uniform blending.
Types of Permanent Haircolor

Oxidation Tints:
- Also known as aniline derivative tints or penetrating tints, these can lighten and deposit color in one process.
- Available in a wide variety of shades; includes toners designed for use on pre-lightened hair.
- Most products include aniline derivatives and require a predisposition (patch) test prior to usage.
- Compatible with other professional chemical services (waves and relaxers) if the hair is in good condition.
- Available in various formats (bottles, canisters, tubes) as semiliquid or cream.
- Must be mixed with hydrogen peroxide to initiate the oxidation chemical reaction immediately upon mixing.
