Study Notes
Hair Coloring Basics
- Clients typically return for color maintenance every four to eight weeks.
- "Haircolor" refers to artificial hair coloring products and services.
Hair Structure and Pigmentation
- The hair's structure and the desired results influence the choice of hair color.
- The cortex contributes approximately 80% to the hair's overall strength and elasticity.
- Melanin is the natural pigment responsible for hair color, found in the cortex.
Hair Texture and Porosity
- Hair texture is determined by the diameter of individual strands.
- Fine hair processes color quickly due to tightly grouped melanin granules.
- Coarse-textured hair has a larger diameter and takes longer to color.
- Porosity is the hair's ability to absorb moisture, categorized into low, average, and high porosity based on cuticle condition.
Understanding Color
- Eumelanin produces black and brown hair colors, while pheomelanin gives rise to blond and red shades.
- Contributing pigment, or undertone, reflects warmth during color or lightening processes.
- The level system is used to analyze hair color's lightness or darkness, with levels ranging from 1 (darkest) to 10 (lightest).
Color Wheel and Relationships
- The color wheel aids in identifying the natural hair level and understanding color relationships.
- Primary colors cannot be achieved through mixing, while secondary and tertiary colors result from combining primary colors.
- Complimentary colors are opposite each other on the color wheel and balance colors.
Tone and Base
- Tone refers to the hue seen in hair, described as cool, warm, or neutral.
- Warm tones reflect more light, appearing lighter; cool tones absorb light, appearing darker.
- Bases are the predominant tones identified in color formulations.
Types of Haircolor
- Non-oxidative haircolor includes temporary and natural colors, while oxidative haircolor includes demipermanent and permanent options.
- Permanent haircolor is best for covering gray hair.
- Patch tests are essential for most permanent haircolors except temporary colors.
Application Techniques
- Single-process haircoloring lightens and deposits color in one application; examples include virgin and color retouch applications.
- Double-process applications involve pre-lightening followed by toning.
- Various techniques like highlighting, lowlighting, balyage, and foil highlighting allow for creative coloring options.
Chemical Components
- Hydrogen peroxide is the commonly used developer for oxidation processes.
- The strength of hydrogen peroxide is measured in volume; 20 volume is standard for most permanent color results.
- Hair decolorizers chemically lighten hair by dispersing natural pigment.
Rules and Safety
- A release statement is required for clients with questionable hair condition requesting chemical services.
