Problem 12Q

How does hydrogen peroxide change hair color?

Step-by-Step Solution:
Step 1 of 3

Solution 12 Q:

Hydrogen peroxide (H2 O2 ) is a strong oxidizing agent. When H2O2  is applied to hair, it oxidizes the dark pigment (melanin,) which gives hair its color. After melanin is oxidized, it no longer imparts a dark color, leaving the hair with the familiar bleached look. Hydrogen peroxide also can oxidize  other components of hair such as -SH containing protein  to sulfonic acid groups, (—SO3H). The oxidation of thiol groups causes changes in the proteins of the hair, making the hair more brittle and more likely to tangle.
