For Tina Nguyen, a Canadian muralist in Belleville, Ontario, Christmas is part of another nativity story: the birth of her hair-accessory business. It all started six years ago, when Ms. Nguyen gave a cousin one of her handmade, pillowy hair scrunchies, inspiring her to sell them on the internet, where they quickly became a hit.
But this Christmas will be the end of that story. President Trump’s protectionist policies have put a significant dent in sales, said Ms. Nguyen, whose company, XXL Scrunchie & Co., relies on American shoppers for half its business.
