    Study Notes

    Natural Hair Color

    • Natural hair colors vary from black and dark brown to red, dark blond, and the lightest blond.

    • Two types of melanin influence hair color:

      • Eumelanin is responsible for black and brown hues.
      • Pheomelanin provides yellow (blond) and red coloration.
    • Key factors affecting natural hair color appearance include:

      • Thickness of the hair
      • Number and size of pigment granules
      • Ratio of eumelanin to pheomelanin in the cortex
    • Gray hair results from decreased melanin production.

    • White hair consists of keratin without melanin, thus lacking both types of pigment.

    Contributing Pigment

    • Contributing pigment is the underlying pigment beneath the natural hair color.
    • Altering contributing pigment is fundamental in hair coloring to achieve desired shades.
    • When lightening hair, darker natural colors reveal more intense contributing pigments.

    Understand Color Theory

    • Color is a property of visible light energy; human sight perceives six basic colors but can visualize various combinations.
    • Combinations of the three primary colors (red, blue, yellow) and three secondary colors (green, orange, purple) lead to diverse color expressions.
    • Hair pigment (natural or artificial) absorbs or reflects light rays, which determines the colors seen.

    The Laws of Color

    • The laws of color define color relationships and guide the mixture of dyes and pigments to create various colors.
    • These principles blend scientific understanding with artistic application to achieve harmonious color combinations.
    • A color wheel visually represents colors in a sequential order, illustrating the relationships between different colors (e.g., equal parts of red and blue produce violet).
