Use as the finishing touch on almost dried hair. (For the best results on curly hair textures, blow out hair smooth and apply rollers while hair is still warm.) Insert the rollers one at a time, focusing on areas where you wish to have the most volume. With curlers in place do one last shot of heat with a blow dryer to warm the rollers and allow them to cool. Once hair is completely cool and dry, gently remove the rollers and style as you wish.
