Understanding Color Theory: The Foundation of Hair Coloring

Color theory forms the backbone of successful hair coloring. The color wheel serves as your roadmap:

  • Primary colors: Red, blue, yellow
  • Secondary colors: Green, orange, purple
  • Tertiary colors: Combinations of primary and secondary

Understanding complementary colours helps neutralize unwanted tones. For example, purple cancels yellow, while green neutralizes red.

What Are the Different Types of Hair Color Products?

Hair color products come in several formulations:

  1. Permanent color:

    • Penetrates the hair shaft
    • Provides complete gray coverage
    • 可持續至頭髮長出

  2. Semi-permanent:

    • Coats the hair surface
    • Gradually fades
    • No ammonia

  3. Demi-permanent:

    • 部分滲透角質層
    • Moderate gray coverage
    • Less damage than permanent

How Does Natural Hair Color Affect the Process?
