Permanent color means permanent.

Of course, there is no hair color that will ever change the color of your hair, so this term is used for the most persistent type of dye.

The basis of such dyes is ammonia, or its analog, a substance that allows the dye composition to penetrate deep into the structure of the hair and replace the existing color pigment with a new one.

In this case, the bonds between the molecules inside the hair are destroyed, and then new ones are built — it is due to this that the permanent hair color lasts so long.
