‘Mousy’ is a term used to describe boring, flat hair. Usually a light brown colour, with no ‘wow factor’. These days most people with mousy hair will either have blonde streaks put in it to liven it up, or colour it a darker, more interesting brown. It doesn’t have to be boring in a straight and flat sense, the hair can be frizzy, straight, curly, wavy etc etc… it just lacks… oomph.

Messy hair, with lots of grease in it. So a greasy look, usually not attractive.
