What is Demi Permanent Hair Color?
Demi permanent hair color is permanent hair color that contains an similar agents other than ammonia and is used with a developer, the concentration of hydrogen peroxide in that developer may be lower than used with a permanent hair color. Since the similar agents included in dem-perms are less effective in removing the natural pigment of hair than ammonia these product provide no lightening of hair's color during dying. As the result, they cannot color hair to a lighter shade than it was before dyeing and are less damaging to hair than their permanent counterpart.
Demi-permanents are much more effective at covering gray hair than semi-permanents, but less than permanents.
