yes you can, depending on how long or short your hair is, if its below your ears, yes but if not, i highly doubt it. you can use GHD's, curling tongs, sock curling methods, ect :)
Of course. You can curl any type of hair, as long as you have the right tools. If you want to use curling or flat irons, you need to find a really thin curling or flat iron. Maybe one that`s 1 inch...
