Sometimes filling in (sparse) brows with pencil is just enough to create a proper definition for the face.
For the beginner, it's best to start out with pencils to fill in brows then slowly/gradually work your way to using brow gel amongst other ways to define the brows.
For some ladies who have sparse brows getting them perfectly shaped comes a little bit difficult but then with practise the brows can be gotten 'on fleek'! To start out, drawing the brows (those with full brows can just fill in the dense areas) or filling them is super easy.
