Whether you’re struggling with hair loss, you simply over-tweezed in the ’90s or you just want to add a bit of definition, the BROW POP Dual-Action Defining Pencil will have you covered.

Delivering hair-like fullness and definition to even the sparsest of arches, this pencil features a triangular tip that imparts both thick and whisper-thin strokes. Precise and richly pigmented, you can use it to fill, shape, sculpt, feather and even blend (thanks to the help of a built-in spoolie). Totally vegan and made without the likes of artificial fragrance, silicone, mineral oil or microplastics, this do-good formula even cares for hairs and encourages hair growth via nourishing castor oil and panthenol provitamin B5.

Use the thin tip of the triangle to create hair-like strokes. Use the thicker side to fill in more sparse areas that need a little more love. Then use the spoolie brush to shape it up and blend the pigment through.

Tip: Layer Air Brow tinted gel and/or Air Brow clear gel over Brow Pop for the full Kosas brow look (peak tint, volume and hold).

Founded by multi-talented LA artist Sheena Yaitanes, Kosas unites impeccable shade ranges with botanical-rich formulas. The result? Make up that’s as good for you as it is gorgeous to look at. The BROW POP Dual-Action Defining Pencil is crammed with nutrient-dense ingredients, feeding brows with castor oil and vitamins while imparting rich, last-all-day pigment that won’t smudge, fade or transfer.
