Every week we take on your questions about makeup, skincare, hair and more and provide all the answers. This week we’re helping you prep for the holiday season with hair and makeup tips that will take you from Hanukkah dinner to Christmas brunch to New Year’s Eve—and everything in between. We suggest a product that will virtually double your entire nail polish collection, reveal the best bright-blue eyeshadow and share a new hairstyle for that big night out.
