The perfect eyebrow is like the pot of gold at the end of the rainbow. JUST when you think you have it, it eludes you one more time. Kylie Jenner's makeup artist, Ariel Tejada, has shared his top brow tips and a step-by-step tutorial on the Keeping Up With The Kardashians star's website and app. One tip in particular hit home with us, and is a mistake we at Her Towers are definitely very guilty of - getting too pencil-happy. Ariel explains:  "the overall objective is to fill in the sparse areas – not to fill in the entire brow." Oops. Spotted on Cosmopolitan, here are the makeup man's top brow rules; Start with the brows Because the brows frame the face, Ariel advises starting your makeup routine here and then working around them. Outline  First Ariel combs the hairs upwards and then with a precise pencil, draws an outline as a "background for the hairs". Choose start and end points "Determine where you want them to stop and where you want them to begin." Fill in sparse areas And ONLY sparse areas. Clean up  Ariel recommends cleaning up the outline with a concealer and a flat brush afterwards. "Start underneath the arch and blend down towards the eyelid." Soon enough you'll be giving Kylie a run for her money.
