The Ukrainian Prime Minister has
gorgeous hair. Among its impressive features are that she can get it to stay that way at all (I've occasionally attempted similar braid pin-ups, but they've always succumbed to gravity).
Sadly, despite a purported
public demonstration of the lack of hair-extension involvement, I'm forced to conclude that the braid can't be completely authentic. If it were, her hair would have to have impressively uniform volume down to at least waist-length, since the braid's diameter doesn't have much visible drop-off from one side to the other. But she doesn't seem to've adopted her current hairstyle until 2005 of so; pix from
2004 show that within the year before that, her hair was only at upper-bosom length, and also that the blonde color is a relatively recent development. I assume that what she must be doing is fastening a waist-length thick cluster of extensions onto her own hair with the elastic for the "low ponytail" at the nape, and then braiding all of it together from there.
