Most people don't realize that in order to wax effectively, your brows should be around a quarter of an inch long (which yes, is a hefty amount of regrowth). That said, you can always use an opaque concealer (such as the popular Nars Radiant Creamy Concealer, $30) on them to camouflage until they're long enough to tweeze.
Threading, tweezing and waxing are the most precise ways to achieve brow perfection. Though tempting, using a razor is just too risky.

Once you have your desired shape, brush your brows up with a clean spoolie brush to create volume and lift. It's also a great way to groom your brows on days when you're in a rush and don't want to do your whole brow routine — simply dab on a touch of Vaseline, spoolie it through and you're good to go.
