Eyebrows are sisters not Twins!
Eyebrows are sisters, not twins I think the one mistake we all make with eyebrows is trying desperately to make them both the same shape.
However we must remember that our brows are sisters and not twins! It does not matter if one brow is more arched than the other, as long as they are similar it looks more natural.
No two eyebrows need be exactly the same The best technique: when filling in the brows, use light, feathered strokes. You want the product you are using to look like brow hairs and not be a block colour, especially at the front of the brow.
