Do American hotels have hair dryers?

At least the five hotels I stayed in in the United States didn't have hair dryers. Americans have no habit of using hair dryers. They set their hair wax when they were dry in hair seven. Because most Americans have curly or slightly curly hair, you can't buy a hair dryer to bring to America. Because the hair dryer can't pass the security check at the airport, you'd better buy one in America. I think my answer is clear enough. I hope I can help you.
