So here's the thing: Everyone is going to have different preferences in terms of tools, and what's more, your brows might require different types of products at different stages.

"Not using

the proper product to 'fake' a brow is one of the biggest mistakes I see when someone is trying to achieve their best shape," Streicher says. "There are many quality brow products on the market now to help people have their best brows, but people aren't always sure how to use them."

"Eyebrow products are incredible," agrees Christine. "Depending on the shape and stage of your brows, you can use pencils, powders, eyebrow gels (either tinted or non-tinted), and eyebrow pens to achieve amazing and believable results." This is something you'll want to discuss on a more personalized basis with your expert, but as for her own approach, Christine says she loves to alternate with her eyebrow filler (which is like a powder but housed in cool, pencil-like packaging that you can also use as an eye shadow and/or eyeliner) and her eyebrow pencil, which will deliver more hairlike strokes. Both, she says, will leave a very soft yet naturally defined finish. I use her pencil every single day to add depth in addition to filling in any sparse areas, and I've never gotten as many compliments on my brows.
