What technique is used to create volume at the roots during a blowout?

The technique used to create volume at the roots during a blowout is overdirection. This method involves lifting the hair away from its natural fall and directing it toward the desired volume area, typically at the roots. By pulling the hair away from the scalp and toward the back or side, stylists can encourage the hair to stand away from the head, creating an appearance of added fullness and body.

Overdirection can be particularly effective when combined with a blow dryer and a round brush, as this allows the stylist to set the hair in the desired position while heat styling. This technique is often utilized in various types of hairstyles to enhance volume and shape, making it an essential skill for achieving a professional-looking blowout. It directly influences the final outcome by essential manipulation of the hair's base structure during the styling process.
