Straight eyebrows run nearly horizontal from the inner corner to the outer tail, with very little arch height anywhere along the brow. The thickness stays even from head to tail rather than tapering sharply, which reads as a clean, linear brow line. This shape is the hallmark of the "soft brow" and Korean beauty aesthetic — it softens the face and creates a youthful, approachable look, particularly on faces with more angular bone structure where it provides welcome contrast.

Straight Eyebrows — Frequently Asked Questions
What makes eyebrows count as "straight"?
A nearly horizontal line from the inner corner to the outer tail with minimal arch height anywhere along the brow, and even thickness from head to tail rather than a sharp taper.
Should I create an arch on straight eyebrows?
No — over-arching fights the natural shape and tends to look unnatural. Tweeze only stray hairs below the natural line rather than carving in a new arch.
What products work best on straight eyebrows?
A brow gel or soft pencil in a natural shade keeps the straight line looking effortless. Fill with light, feathery strokes rather than a defined arch.
