Wondering about hydrogen peroxide

  1. Oct 21, 2009 #1
    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.
