Now we're starting to get into the heavy hitters. Brow pencils come in a wide variation of formulas and packaging. Whether you pick a powdery pencil that needs sharpening or an automatic one that glides on with ease, keep an eye out for a product that's double-ended with a spoolie brush on one side. This will allow you to shape your arches to perfection pre- and post-penciling. Tip: start with light, feathery strokes that mimic your actual brush hairs, then fill in more heavily in sparse areas.
