19 Times Jessica Simpson's Hair Was The Highlight Of The Early 2000s — PHOTOS

While she may be infamous for her millennial pop anthems, short-lived marriage to Nick Lachey, and dubious comments regarding tuna, Jessica Simpson's hair is another integral component of the performer's unique brand of quirk. Simpson's three-year stint on Newlyweds may well have been the longest running haircare advertisement in television history, as well as a warning to young couples flirting with the notion of marriage. Playfully tousled curls, elegant updos, and fedora-covered ponytails danced across the screen in alluring succession, cementing Simpson's status as the coiffure guru of the early aughts. If Seventeen featured a burgeoning hair trend between 2000 and 2005, chances are Simpson flirted with the style for one of her many red carpet or television appearances.

Now a successful business owner and noted fitness guru, Simpson's style has mellowed over the years; however, there is something to be said for reminiscing about the moments when the chanteuse's agenda was simply aesthetic. After all, who could forget the braided half updo Simpson debuted for her "I Think I'm In Love" music video, or the backcombed, crimped coiffure Simpson rocked at 2001's Presidential Inaugural Opening Celebration? Take a stroll down memory lane and revisit 19 of Simpson's most covetable early aughts 'dos, but bear in mind that tiger stripe highlights and crimped locks are best left to hair history.
