A recent visit to brow expert Lucy R. confirmed what I’d suspected for some time now: Not only are my eyebrows disproportionately shaped; they’re also not even on the same level. They share completely separate longitudinal coordinates. If my eyebrows were trains featured in a math problem about intersection, they’d just run perpetually parallel past each other while waving goodbye. Which is why I’m now in what Lucy lovingly calls “brow rehab,” hoping to fix this issue once and for all. But until then, as my brows are slowly grown in and guided back to where they once were, I’ll be faking the perfect shape with the help of a few tools. Read on for an easy step-by-step tutorial on how to properly fill in your brows.
