Blame it on The Wolf of Wall Street, or Men's Fashion Week—hair gel's definitely having a moment. One of the most dapper men on this earth, W Magazine editor-in-chief Stefano Tonchi, goes through an entire bottle of Kiehl’s gel every two weeks! Gelled hair is a look that means business because it’s all about control, whether you’re in a YSL Le Smoking  or a bathing suit . There are few things that say, "I am not to be f-ed with" more than slicked, not-going-anywhere hair—especially on a woman. So invest in some L.A. Looks and get to combing.
