These looks prove the modern shag is the ultimate lazy-girl haircut for autumn/winter

The shag haircut has been doing the rounds for a couple of years now, but as one of the ultimate 'cool girl' hair trends, it's not going anywhere anytime soon. 

The shag is defined by its choppy layers, root volume and relaxed feel. When cut correctly, it has glorious texture and is messy but in a highly stylish way. It has a distinct '70s feel (much like the fox cut), and has similarities with other messy, texture cuts such as the mullet. 

Perhaps the best thing about the shag is that it's one of the easiest hairstyles to wear: as well as looking ultra-casual and care-free, it is incredibly low maintenance for styling (again, if cut well). For natural wavy or curly hair (particularly for curly bobs), this can be a go-to style if you're often short of time; it's the kind of cut you can get up and go with. 

Modern iterations of the shag include the 'shixie' (the shag pixie) and the 'shullet' (the shag mullet). But really, there are so many ways to wear it, no matter your hair length—short or long.
