Spiral Perm, digital Perm, Korean Perm, Japanese Perm, Body Perm, Wave Perm - there are so many names out there right now it makes my head spin. I wouldn't be the least bit surprised if you're confused about which kind of hot perm to get. Honestly, they're all the same thing. It's the size of the curl-roller and the application of heat during the process that matters. And OF COURSE, the skill of your stylist.
