A permanent wave, commonly called a perm, is the chemical and/or thermal treatment of hair to produce waves, curls or straight hair. In cosmetology, it is termed a type of curl reformation of the hair. BRIJON provides four “permed” styles (Body Wave, Deep Wave, Jackson Wave and Yaki) that have been processed through a very delicate thermal treatment that does not damage the quality or integrity of the hair. The hair will maintain its wave, while not using damaging chemicals to produce the waves.
