By now I have done so many buns, that it often feels like a naughty cheat, because it always looks good and doesn't take any time at all. Well, of course, there's a reason for that: I have methods to ensure that hair stays put and looks effortlessly elegant with just a few basic techniques.
My favourite is 'the pony-plait'. I simply tie hair in a low pony, then plait and fasten the end with a hair tie. I then reach for some grips and pins and roll hair around the pony hold, and pin in place beautifully. This can be a loose and romantic bun, or a neat and sleek bun...it really just depends on your tension in the braid.
Either way, it will look styled in no time at all. And off you go, because you should do the traveling, not your hair.
