Study Notes
Hair Color Reasons
- Hair color is used to cover gray, enhance existing shades, make fashion statements, express individuality, correct unwanted tones, and accentuate haircuts.
Hair Porosity and Color
- Porous hair absorbs color more quickly, potentially resulting in cooler tones.
- Porosity categories include low (long processing time), average (average processing time), and high (quick application but prone to fading).
Types of Melanin
- Eumelanin: presents in black and brown hair.
- Pheomelanin: found in blonde and red hair.
- Mixed melanin: a combination of eumelanin and pheomelanin.
Level System in Haircolor
- Color level is indicated on a scale from 1 to 10, representing lightness to darkness.
- This system aids in determining the depth of the desired color.
Color Categories
- Primary colors: Blue, Red, Yellow.
- Secondary colors: Violet, Orange, Green.
- Tertiary colors: Blue-Violet, Red-Violet, Blue-Green, Yellow-Green, Yellow-Orange, Red-Orange.
Tone and Intensity
- Tone refers to the color balance (warm, cool, neutral).
- Intensity indicates color strength (soft, medium, strong); color intensifiers can enhance the results.
Categories of Haircolor
- Temporary Color: Coats hair without penetrating, easily washed out, bold results.
- Semipermanent: No lift, lasts several shampoos; subtly deposits color.
- Demipermanent: No lift, enhances natural color, and refreshes faded hair.
- Permanent: Lightens and deposits color simultaneously, effective in covering gray.
Hydrogen Peroxide Developer
- Acts as an oxidizing agent that enables color change when mixed with an oxidation haircolor.
- Strength is measured in volume; lower volumes result in less lift, while higher volumes provide greater lift.
Four Key Formulation Questions
- Assess the natural level and presence of gray.
- Identify the client’s desired level and tone.
- Consider any contributing pigments that may be revealed.
- Determine which colors need mixing for desired results.
Patch Test Importance
- Conducted to identify potential allergies or sensitivities to haircolor chemicals.
Preliminary Strand Test
- Determines hair's reaction to color and optimal processing time.
Hair Lighteners Action
- Lighteners disperse, dissolve, and decolorize natural pigments using chemical compounds.
- Oxygen is released during the oxidation process to diffuse hair pigment.
Procedure for Virgin Single-Process Color
- Steps include draping, applying gloves, sectioning hair, applying color starting from resistant areas, processing, rinsing, and conditioning.
Double-Process Haircolor
- Involves two steps: first, hair lightening or bleaching; second, depositing the desired tone.
Forms of Hair Lightener
- Oil Lighteners: Mildest, suitable for the scalp, lightens up to two levels.
- Cream Lighteners: Stronger for high-lift blonding, good for scalp application.
- Powder Lighteners: Quick application, must be used off the scalp.
Toner Purpose
- Used post-prelightening to achieve delicate and pale colors, often employed after dimensional hair color services.
Highlighting Methods
- Cap highlighting: Pulls strands through a perforated cap.
- Foil highlighting: Slices or weaves sections, wraps in foil for processing.
- Balayage: Freeform technique where color is painted onto styled hair.
Tips for Gray Coverage
- Formulate colors at level 7 (medium blonde) or deeper.
- Use 20-Volume developer for best results.
- Process for 45 minutes, adjusting natural tones based on gray percentage.
Color Correction Rules
- Stay calm when addressing color problems.
- Identify the nature and cause of the issue.
- Develop a solution and take gradual steps.
- Perform strand tests for verification of results.
Safety Precautions in Haircoloring
- Conduct patch tests, avoid abrasions and metallic colors.
- Use clean tools, protect clothing, and always wear gloves.
- Follow instructions carefully and perform strand tests before full application.
