Bleaching is a chemical reaction.
when you bleach your hair it is a chemical change,because you are adding the chemical from the bleach to your hair and "you can't change it back to the old". chemical change: you can't change it back to the old and it makes a new subtance. physical change:it does not make a new subtance and it is still the same object.
