If you're still on the fence about whether you want highlights or lowlights, may we suggest both? "Unless you want streaky highlights with tons of contrast, there's a good chance your colorist will tone down and blend the color with lowlights, whether they're placed along your roots for volume or throughout your hair for texture," according to Cosmopolitan.

Most celebrities opt for a combination of highlights and lowlights to create their signature look, so if you're envious of Jennifer Lopez's multi-dimensional hair, you'll want to follow this approach. The cost increases when you couple lowlights and highlights, which is something to bear in mind if you're budget-conscious when it comes to your hair. Lowlights are typically less maintenance and only require touch-ups every two to four months, whereas highlights require touch-ups every six to eight weeks, per Cosmopolitan.

Discuss what you want with your stylist, both in terms of your overall color and your maintenance preferences, before taking the plunge one way or the other.
