DIHYDROXYINDOLINE

Description

Dihydroxyindoline is a potent hair color molecule that plays a crucial role in permanent hair dye formulations. This synthetic compound is designed to mimic the natural melanin pigments found in human hair, particularly eumelanin, which is responsible for dark hair colors. When oxidized, dihydroxyindoline polymerizes to form a stable, long-lasting color within the hair shaft.

The molecule's structure allows it to penetrate the hair cuticle effectively and bond with the cortex, resulting in a more natural-looking and fade-resistant color. Dihydroxyindoline is particularly effective in creating rich, deep shades of brown and black, making it a valuable component in hair dyes targeting gray coverage and dark color enhancement.

In hair dye formulations, dihydroxyindoline is typically combined with other color precursors and an oxidizing agent, such as hydrogen peroxide. This combination triggers the polymerization process, which forms the final color within the hair. The compound's stability and color-forming properties contribute to the longevity and vibrancy of the hair dye, offering consumers a more durable and satisfying coloring experience.
