Chrissy Teigen has never been shy about sharing her beauty favorites with the world. The model, cookbook author and queen of unfiltered social media took to her Instagram Story to shout out a product that's become part of her routine: the Ouai Scalp and Body Scrub. And considering it's on sale right now, it's one of the more accessible celebrity beauty picks we've seen in a while. Oaui has serious beauty-world credibility, and it's no surprise Teigen said she adores the scrub for head-to-toe exfoliation.
