Since the early 2010s, style and beauty have both cycled back in time to the 1980s and 1990s: All clothes are high-waisted now, blue eye shadow has come back into style, and light-wash jeans are finally acceptable as a fashion choice again. In 2019, though, trendsetters decided that the ’80s wasn’t far back enough for beauty inspiration — hence the recent obsession with the 1970s aesthetic. Case in point: The shag haircut.

The distinctly layered style has been outshined by blunt-cut bobs for a while, but this fall, it’s become impossible to ignore thanks to hairstylists and celebrities. Holly Seidel, a Los Angeles-based stylist specializing in the shag cut, thinks it’s the cut’s inherently rebellious nature that’s kept it relevant over decades.
