In the United States, it is the Federal Communications Commission, or FCC. And its jurisdiction doesn't stop at radio, but also extends to television, the Internet and really any form of communication extended over air or wire.
Wash your hair with a gentle moisturizing shampoo made for chemically treated hair on day three. These shampoos will have natural, soothing ingredients for those stressed tresses after a perm. Use gentle massaging motions on the hair and rinse thoroughly. Only use warm water when washing your perm, never hot.
Although new hair growth will be a factor after a couple of months, perms can last for up to six months with gentle care and treatment. To make a perm last longer, avoid heat styling as much as possible. Use a hair-dryer diffuser to help retain the curl of the perm and soften the damage of heat styling.
