I recently went in to have my hair done, and when they were styling it, the stylist was using one of the flat-iron curlers like you would use to straighten your hair. I had no idea that these could also be used for curling the hair; but they not only are great for curling the hair; it looks to me like they will do a better job than the curling iron that i have been using to curl my hair. I watched a few tutorials on youtube, and then ordered myself one of the flat-irons from Amazon, and am hoping to be trying it out by tomorrow. I only have short hair right now; but it looks to me like these irons will also do an awesome job for curling longer hair. Here is a short tutorial showing how they work.
