Korean Digital Perm

 "Digitally Permed curls are less coiffed, sculpted, and defined. Hence, they are usually looser. And, they look more like people with natural waves than those carefully-styled curls designed using a curling or flat iron." 

 Digital Perm is a hair retexturizing technology that uses heat and chemicals to change its shape into curls and waves.  The only perm treatment without perm solution during curl forming process.
