TL;DR: In this paper, the hair of a human head is looped into waves of circular shape, ready for the ordinary liquid treatment for temporary waves known as water, and a frame and operating device are provided to loop the hair into the shape of a circle.
Abstract: This invention relates to devices for forming waves in the hair on human heads. The objects of the invention are to provide a frame and operating device, whereby the hair may be looped into waves of circular shape, ready for the ordinary liquid treatment for temporary waves known as water...
TL;DR: The study provides insights into the dynamic states of adult skin and physiological regulation of organ regeneration and two non-invasive methods to track the propagating hair wave in large populations of hair follicles in vivo are described.
