I always forget something when I pack for a trip, and this time, it was a Davines product—which I spritz on damp hair to protect and glossify it—that got left behind. I was slightly bereft, as I couldn’t imagine another product doing the job quite as well. But I took a chance on this leave-in conditioner from Whole Foods, and I must say it’s kind of a miracle. It detangles brilliantly, and leaves my hair smooth and virtually frizz-free. And it doesn’t make your hair feel heavy and sticky, the way some leave-in conditioners can.
