These are haircut styles that involve cutting the hair into various lengths with layers, keeping the hair full and voluminous at the crown of the head (hence the characteristic bold bangs often seen in these cuts), while the ends are thinned out, creating that shaggy look. The term "shag" has been used for these types of haircuts for decades, dating back to the '70s and '80s. Today, we also see other names being used for this style, such as the mullet and the wolf cut, with the differences lying in how extreme we want the haircut to be. For daring fashionistas, the mullet is the ideal choice, while for those who prefer something in between, the wolf cut is what they're looking for.
