Abstract: A method and device facilitating the optimal degree of processing of hair during permanent waving (perming) of hair. As a critical part of a combination of otherwise conventional sequential perming steps, the inventive method vacuums moisture from rod-mounted hair following the water rising of waving lotion from the perm processed hair. The vacuuming device includes a cover worn on the head substantially sealed around the mounting periphery thereof, with the cover forming free-space above and around the rod mounted hair and with the cover having channel structure channeling outer ambient room temperature air toward hair roots of rod-mounted hair.
