Wearing scarf everyday?

HI ! I recently bought a new scarf since I lost my old one. I have never been a really big fan of scarfs so i never wore them more than once every now and then. In norway there´s very cold climate and i am just wondering if there is normal/ok to wear the same scarf every day or should i buy another one in another colour to vary? I am going in 1st grade, High school. Thanks for your help!
