Wondering about hydrogen peroxide

[AutisticAlien]

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.
