Sif is Thor’s wife, best known in the pantheon for her awesome shock of magical golden hair.

Many winters ago, Loki cut off Sif’s lovely blonde hair as a practical joke. When Thor threatened to bash in Loki’s brains, Loki had some dwarves make Sif some new, magical hair. The hair looked kind of like a wig, but when Sif put it on, the hair fastened to her head and became the real deal — except this time it wasn’t just gold in color, it was real gold!

At first Sif didn’t like her new doo, since hair made out of gold is such a bitch to wash. But then she realized… hey, she’s got magic hair!
