20 New Beauty Launches You Need in Your Stash This Summer

What it is: IGK Prenup Instant Spray Hair Mask ($32)

Why you need it: This genius formula was inspired by the concept of Korean splash masks, which pack the deep hydration of a heavier mask into a lightweight liquid. You use this milky conditioning spray in the shower, then immediately rinse it out. Once you dry and style your strands, you'll notice that the reparative senna leaf extract, cupuacu butter, and nourishing amla oil penetrated your hair and left it soft, silky, and manageable. Bonus: it smells like a tropical vacation.
