I think I'm a little late to the game with this one, but I recently discovered the Spin Pin by Goody and it is changing my life. Ok, so maybe that's a bit of an exaggeration, but it is changing my hair life. The Spin Pin is making my life better by saving me time and energy on achieving the perfect bun and beachy waves.
Here she is, the Spin Pin.
It's easy, you twist and wrap your hair the way you would for a bun but instead of using a million bobby pins or trying to tie an elastic around it three times, you just spin the two pins into the base of the bun (on opposite ends). You don't even need an elastic to hold the hair in a ponytail first. Your bun stays put all day and doesn't leave you with dents or a headache from being wound up too tightly. It's great, too, because the Spin Pin holds any type of bun—from a slick, clean one, to a messy, loose one.
For beachy waves, wash your hair and let it dry until slightly damp. Add some product, spin into bun and finish with the pin. Once dry, remove the pin and you're good to go.
