Just as you would normally find a hair dryer in your hotel room, most cruise ships provide hair dryers, too. They might be in the bathroom, on the desk, in the closet or mounted on the wall.  

Depending on the cruise line, it might be a low powered one. Just as with hotels, hair dryers are an expected commodity, but not one that hotels or cruise lines want to pour a bunch of money into. 

They can be a standard, run-of-the-mill model or an outdated version with a  short connecting cord. 

You might put some thought into how you can style your hair without the use of a hair dryer so if you have an inferior model in your cabin, it won’t matter. 

If your hair dryer from home is a favorite that you can’t get along without, you can bring your own from home. If you only use one periodically, save the space in your luggage and use the one provided in your cabin.
