chemical process that creates long-lasting curls or waves in hair
Perming, also known as a permanent wave or simply a perm, is a chemical process used to alter the structure of hair to create curls or waves that last for an extended period. This involves applying a chemical solution to break the hair's natural bonds, reshaping the hair around curlers or rods, and then applying a neutralizer to reform the bonds in the new shape.
