Basically its a hair technique that straightens your hair out nice and straight and it lasts for several months almost a year. they use a special chemical to seal it. Theres also another way to get silky straight hair for months, its called a Brazillian Blowout. My freind has it and it looks fabulous.
Its the opposite of a perm, it uses chemicals to make your hair straight, and its really bad for your hair, but it does work i think. My firend had a friend who got it and she likes it, her hair was really straight.
