"I've been travelling a lot this month, so I've had to swap my full-size hair products for a selection of minis. Luckily, celebrity hairstylist Kristin Ess dropped a travel-size bottle of her bestselling Dry Shampoo — Kristin Ess Mini Dry Shampoo ($5) — before I left for my trip. That meant I could do what everyone is supposed to do on holiday: sleep in more and shower less, without looking like a greaseball by the end of each day — or worrying about it getting confiscated by TSA." — Kelsey Castañon, senior editor, Beauty
