Study Notes
Hair Coloring Concepts
- High-lift tints are mixed with 30 or 40 volume hydrogen peroxide for achieving lighter colors.
- On-the-scalp lightener does NOT darken the natural pigment; it lightens hair.
- Stages of Lightening: Dark hair can go through 10 stages of lightening or decolorization.
- Permanent hair colors are also known as oxidative tints with ammonia, essential for long-lasting color results.
- Off-the-scalp lighteners are preferred for creating special effects, like highlighting.
Processing Factors
- The amount of natural pigment significantly affects processing time during hair decolorization.
- When over-lightened, hair may appear ashy or gray after applying a toner.
Color Terminology
- Long-lasting semi-permanent colors use low-volume hydrogen peroxide, suitable for depositing color or adding tone.
- Fillers are used to replace missing primary colors, providing a uniform base, especially when correcting color.
- Oxidative colors are products that initiate a chemical change when mixed with a developer, often hydrogen peroxide.
Developer Insights
- Hydrogen peroxide is the most commonly used developer or oxidizing agent in hair color services.
- Typically, hydrogen peroxide has a pH ranging from 2.5 to 4.5; when combined with ammonia, it allows for lift and lightening.
- Mixing bowls made of metal may weaken hydrogen peroxide, so non-metal options are preferred.
Color Application & Techniques
- Cream hair colors are mixed with a cream developer and applied using a bowl and brush for precise application.
- Demi-permanent colors require low-volume hydrogen peroxide for developing color molecules.
- A double-process technique involves lightening hair first, followed by recoloring to desired tones.
Hair Lightening and Toners
- Lighteners diffuse or remove pigment, and their effectiveness is enhanced by ingredients like ammonia.
- Toners are used to add warmth or coolness to pre-lightened hair, with pastel colors being favorable for this purpose.
Safety and Testing
- A predisposition test is crucial for toners due to the presence of aniline derivatives that can cause allergic reactions.
- A skin patch test is mandatory for products containing aniline derivatives to ensure safety.
Duration and Effectiveness
- The shelf life of hydrogen peroxide is approximately 3 years, and its effectiveness is gradual.
- A 20 volume hydrogen peroxide solution typically lifts hair two levels, while 30 volume lifts three levels.
Corrective Measures
- If the desired lift is not achieved, prelightening may be required for additional lightening before application of color.
- To neutralize brassy tones after pre-lightening, toners are applied, ensuring a harmonious final result.
Important Notes
- Hair should never be lightened to white as this can damage hair integrity.
- Products that lift existing color and deposit new color in one process are classified as permanent colors.
