The spell I'm going to use on those four is Makeover (the same I used for the 'magical showers'). According to the book (Street Magic p173) it can do anything you can get done in a beauty salon. So I assume, but want to make sure before I start rolling, that this includes changing hair colour, doing up nails so people look more like business people instead of street fighters and giving them a tan like a tanning bed or a chemical tan. They will probably be recognised up close, but from a distance they can look different, especially if they change their clothes as well.
