Study Notes
Metallic Dyes
- Metallic dyes darken hair with each application and are termed progressive dyes.
Hair Porosity
- Resistant porosity features smooth cuticles, making it challenging for color penetration.
Melanin and Hair Color
- A predominant quantity of pheomelanin produces red hair.
Coloring Processes
- Semi-permanent coloring involves both large and small color molecules, allowing smaller molecules to penetrate deeper into the hair.
Hair Breakage
- Hair breakage may occur with hair previously treated with henna, metallic dyes, or compound dyes, but not with weekly rinses.
Color Wheel
- Complementary colors are situated opposite one another on the color wheel, enhancing each other's presence.
Resistant Hair
- For more resistant hair, colorists may need to pre-soften or pre-lighten to facilitate better color absorption.
Application Tools
- Cream hair colors are applied using a bowl and brush after being mixed with cream developer.
pH of Hydrogen Peroxide
- Hydrogen peroxide, commonly used as a developer in hair coloring, has a pH level between 2.5 and 4.5.
Color Molecule Size
- Semi-permanent products can penetrate the cuticle better than temporary colors because their color molecules are smaller in size.
Observation Levels in Hair Coloring
- The three levels of observation in hair coloring include basic, detail, and abstract.
Hair Color Level System
- The level system is used to identify the lightness or darkness of hair colors.
Lighteners' Functionality
- Hair lighteners contain ammonia and peroxide, which help break down melanin in the hair.
Color Design Principles
- Contrast creates a relationship of opposites, making certain design elements stand out.
Discouraged Color Products
- The use of metallic and compound dyes is discouraged due to potential damage.
Cool Colors
- Blues are classified as cool colors, which can influence the overall hair color effect.
Hair Texture & Processing
- Coarse hair may process lighter than the intended color level.
Level of Color
- Level 12 is recognized as the lightest hair color level.
Design Texture
- The texture of a design can be altered by the color pattern employed.
Addressing Unwanted Tones
- To neutralize unwanted orange tones, blue-based colors should be applied.
Fillers
- Fillers are effective in preventing off-color outcomes and achieving uniformity in tint back but are not designed to lift and deposit color simultaneously.
Contributing Pigment
- Contributing pigment consists of the client's natural melanin combined with any previously applied artificial color.
Reasons for Color Change
- Common motivations for changing hair color include covering gray, enhancing existing color, and creating fashion statements.
Hydrogen Peroxide Volume
- A 20 volume hydrogen peroxide solution generally lifts hair by 2 levels.
Attention in Color Design
- Repetition in color design can divert focus from texture and emphasize the overall silhouette.
