The technique used for creating volume at the roots during a blowout is over-direction. This technique involves directing the hair away from its natural fall or the way the hair tends to lay. By lifting the hair at the roots and directing it away, stylists can create lift and volume that enhances the overall appearance of the hairstyle.

When performing a blowout, over-direction emphasizes the growth patterns of the hair, allowing for fuller body and bounce. This is particularly effective because the heat from the blow dryer combined with the tension applied while manipulating the hair helps to set the volume as the hair cools.

In contrast, under-direction would typically flatten the hair and is not conducive to creating volume. Blow-drying, while essential for the entire process, does not specify the technique to create lift and volume at the roots specifically. Flat-ironing focuses on straightening the hair rather than adding volume. Therefore, over-direction stands out as the most effective technique for achieving volume at the roots during a blowout.
