Some people can't wait to get their hands on the clothes that come down the runways, but we geek out over the beauty product launches. Behind the scenes at the runway shows, beauty brands often tease new product launches; some of them, we'll have to wait until spring to add to our collection. Here's a sneak peek at an assortment of spring 2015 hair, makeup and nail polish launches that are well worth the wait.

Nothing gets our hearts pounding quicker than the thought of Nars designer collaborations (besides maybe that umpteenth cup of coffee we drank at 3 p.m.). So when we found out that British designer Christopher Kane was collaborating with the beauty brand, we were understandably giddy.

The collection, featuring products for eyes, lips and cheeks, was previewed earlier today in London during the designer's S/S 15 show, and will be available for purchase next May (we've already started a countdown).

The inspiration for the hair at Tracy Reese's runway show was "ballerina after rehearsal." The crux of the look: Scunci's no-slip grip headbands. Next spring, look forward to these in exclusive colors matching the Pantone colors of Tracy Reese's collection.

If we seem grouchy, it's only because springtime can't come soon enough. That's when we'll be able to add this still-unnamed Jin Soon nail polish (which she describes as "moody green") to our collection.

This sheer, nude polish (called Like Dreamers Do) from Deborah Lippmann was used on models at the Theory show. It's the perfect palette cleanser to transition us from deep, rich winter polish shades to bright, spring-ready pops of color.
