Wondering about hydrogen peroxide

Click For Summary
SUMMARY

Hydrogen peroxide is a bleaching agent that alters hair color by oxidizing the dye molecules present in the hair. This process effectively destroys the dye, allowing for a lighter hair color. Understanding the role of melanin is crucial, as it is the natural pigment in hair that interacts with hydrogen peroxide during the bleaching process.

PREREQUISITES
  • Chemistry of oxidation-reduction reactions
  • Understanding of hair structure and melanin
  • Knowledge of hair dye composition
  • Familiarity with chemical straightening techniques
NEXT STEPS
  • Research the chemical properties of hydrogen peroxide in hair bleaching
  • Study the interaction between melanin and various hair dyes
  • Explore different hair dye formulations and their reactions to oxidizing agents
  • Learn about safe practices for chemical hair treatments
USEFUL FOR

Cosmetologists, chemistry students, hair colorists, and anyone interested in the science behind hair bleaching and dyeing processes.

How does it bleach hair? My Chemistry professor at college told us about how chemical straightening works, but failed to explain how peroxide can change hair colour.

Thanks a bunch!

Basically hydrogen peroxide destroys dye by oxidizing it. To check details you have to check what dye is present in hair. Melanin comes to mind as a good starting point in search.
