It's the result of a series of chemical reactions between the molecules in hair, pigments, as well as peroxide and ammonia, if present. Bleach is used to lighten hair. The bleach reacts with the melanin in hair, removing the color in an irreversible chemical reaction. The bleach oxidizes the melanin molecule. The melanin is still present, but the oxidized molecule is colorless.
the same as what black said...
you need a demonstration? get a bottle of bleach. take to a toilet, pour said bleach down toilet. come back 12 hours later. if that toiilet is not pure white under the water line, i will eat ..hmm... cavier! i HATE cavier!
basically, it removes any colour and pigment there. and as such should be used with caution.
plain english it lightens your hair but just be careful how much bleach you use don't want to damage your hair. On brown hair it turns like a blondish color sometimes it will spot depending on your hair. If its your first time bleaching your hair do a test strip and see how the results come out, if you like the results well proceed with the bleaching.
ugh i hate it when people bleach their hair is that even safe O.o it doesnt seem like it
it turns as light as it can. almost blonde
soo what happens if you bleach brown hair
