"I'm way overdue for a haircut (like, it's bad), so these days my ends are looking a tad overgrown, dry, and damaged. To help my hair look smooth and stay as healthy as possible, I've been leaning on the Playa Monoi Milk Leave-in Conditioner ($24). Not only does it smell like the beach-in-a-bottle, but it is crazy conditioning and tames my frizzy strands. I love that it has a built-in heat protectant, too. I just spritz it on damp hair and blow dry away." — Samantha Holender, assistant editor, Makeup.com and Skincare.com
