Study Notes

Hair Coloring Overview

Clients typically visit salons for hair coloring every 3-12 weeks.
Hair coloring is seen as one of the most creative and inspiring salon services.

Reasons for Hair Coloring

Cover or blend gray hair.
Enhance existing hair color.
Create fashion statements or express individuality.
Correct unwanted tones from environmental exposure.
Accentuate specific haircuts.

Hair Structure and Characteristics

Hair has three main parts:
- Cuticle: outermost layer.
- Cortex: middle layer known for strength, elasticity, and pigment.
- Medulla: innermost layer with no significant function.
The cortex is where natural pigment (melanin) is found.
Melanin determines the natural color of hair.
Hair texture is determined by the diameter of individual strands.

Hair Types and Processing

Fine hair has tightly grouped melanin granules, processing color quickly.
Coarse hair takes longer to process color.
Hair density refers to the number of hairs per square inch and can vary from thin to thick.
Porosity describes the hair's ability to absorb moisture.

Porosity Levels

High porosity: cuticle is lifted, hair takes color quickly.
Low porosity: tight cuticle, resistant to color absorption.
Average porosity: slightly raised cuticle, processes in an average time.
Low porosity leads to a smoother hair feel, while extremely porous hair processes color rapidly.

Identifying Natural Color

Learning to identify a client's natural hair color is crucial for successful coloring services.

Melanin Types

The cortex contains three types of melanin:
- Eumelanin: dark pigment.
- Pheomelanin: light pigment.
- Mixed melanin: combination of both.

Color Theory

The law of color helps understand color relationships.
Base color refers to the predominant tone of a color.
Primary colors: red, yellow, blue; these are used to create all other colors.
Secondary colors, created by mixing two primary colors, include green, orange, and violet.

Balancing Color

Complementary colors neutralize each other; for example, blue balances orange, red balances green, and violet balances yellow.
Tones can be described as warm, cool, or neutral, affecting how colors appear.

Hair Coloring Products

Hair coloring products fall into two main categories:
- Non-oxidative: temporary and semi-permanent.
- Oxidative: demipermanent and permanent.
Ammonia or substitutes are important for raising hair cuticles, increasing dye penetration, and starting lightening action.

Hair Color Types

Temporary hair color coats the hair and can be removed by shampooing.
Semi-permanent lasts 4-6 weeks.
Demi-permanent is designed to deposit color without lightening.
Permanent color can both lighten and deposit color in one process.

Developer and Lighteners

Hydrogen peroxide is the most commonly used developer, classified by volume measuring concentration and strength.
Lighteners disperse and decolorize natural pigment to create lighter shades.
Decolonization may involve up to 10 stages to achieve the desired lightness.

Consultation and Application

A thorough consultation is vital for client satisfaction, requiring additional time.
Techniques for applying permanent color include using an applicator bottle or a non-metallic brush and bowl.

Special Considerations

Henna represents natural or vegetable colors, which do not lighten hair.
Metallic colors can cause a dull appearance and restrict chemical service types.
A soap cap combines permanent color with shampoo to create a lighter, foamy consistency during the service.
