A friend of mine was raving about Spin Pins the other day, and about how they’re impossible to find in NYC, so I had to investigate. A Spin Pin, made by hair gadget guru Goody, is a double-helix spiral shaped pin that helps keep updos in place. They come in regular and mini sizes and I’m going to go out on a limb here and say they’re the best things to hit hairstyling since the humble bobby pin. I don’t really have enough hair for a proper updo, but I put a Spin Pin into a hunk of my hair and it didn’t move. Using a Spin Pin is intuitively easy--you just screw it into a twisted updo (no elastic or hair bungee required) and it holds everything together. I’m sure there’s some sort of physics theory to explain how it works, but let’s just leave it at this: it works.
