Sine Qua Non has started a new craze: the Gemstone Blowout, a frizz-reducing, shine-enhancing blowdry using a blend of Bumble and Bumble products infused with crushed pearl, tourmaline, Brazilian green malachite and sapphire.

Tourmaline hairstyling tools have become the new gold standard of styling technology, so the idea of adding these ingredients to product makes sense. I left with a shiny, bouncy blowout that still looked great the morning after.

With a dash of hair powder, I’m told I can milk this style for three days. The service (normally $55) is discounted on Blowout Thursdays at all four Sine Qua Non locations.

$35, for locations

PS: Here's how it looked on me:
