Summer is the season of open windows with delicious smells wafting in on a warm breeze. And since we're definitely in the midst of a chilly Spring in NYC, we're depending on our trusty Kai Perfume Oil ($48) to bring the scent of the tropics to us! (Did you get it in your POPSUGAR Must Have box this month? We did!) The notes of gardenia, jasmine and lilies are a distinctly sweet take on the exotic — no wonder this cult-favorite scent counts Jennifer Garner and Naomi Watts as fans.

To get the most out of the oil, dab it on your pulse points where your body heat is naturally higher: inside of your wrists, the base of your neck, and behind your ears. Or take a little and polish the end of your hair with it for a natural defrizzer and a way to let the scent drift off of you as you walk. Now, when is Summer arriving again?

We love it so much, we included it in our April POPSUGAR Must Have subscription box — find out more and join in the fun!

Spring is finally in the air, and with that comes a flurry of social invites to outdoor drinks, rooftop parties, beach weddings — i.e., events that wreak havoc on the most carefully styled hair. Black 15in1 has long been a go-to for its hair care that seems to do everything all at once, and now that magic has moved into 15in1 hair spray ($9-18). Yes, you heard us. A brand-new aerosol hair spray that treats your hair as it keeps it from flying into your lip gloss.

Not only is it maximum hold, but it also has built-in UVA and UVB protection that's ideal for color-treated hair when you are standing outside at the aforementioned events, so you don't have to worry about your blond locks going brassy. And it's formulated to be humidity-proof, which we will definitely need come the steamy days of Summer. Treatment and a long-lasting style for under $20? Sign us up.
