Curved Eyebrow Barbells

The bar the eyebrow piercing was built for: a 16G curved barbell that follows the brow so the balls sit flat and nothing snags. Plain steel and matte colors from a few dollars, opal, CZ and gem ends, implant-grade titanium and solid 14k gold, in 5/16 and 3/8 inch. The same bar fits rook, daith and vertical labret piercings, and we say so on every page. Since 1999.

Curved Eyebrow Barbell Fit Guide

Fit: 16G is the eyebrow standard, 18G the finer option, 14G for fuller brows. Length is the gap between the balls: 5/16 inch (8mm) for a snug fit, 3/8 inch (10mm) for a thicker brow or swelling room. The eyebrow is a surface piercing, so a bar that is too long levers against the skin and encourages migration; too short pinches. Snug and following the curve is the whole trick. Balls run 3mm classic, 4mm bold. Match the bar you wear now; every product page lists gauge, length and ball size.

Threading: internally threaded and threadless bars are smooth where they pass through the skin, the pick for a brow that is still settling; externally threaded bars are the classic and fine once healed. Slide the bar in from below following the curve, screw the top ball snug with dry fingers, and check it every few days; eyebrows lose balls because the bar sits exactly where you rub your face.

Metal: 316L steel suits most people and holds a trace of nickel in the alloy; titanium is the nickel-free pick; solid 14k gold is the forever one. Many listings here are cross-titled as rook or vertical labret jewelry because it is the same 16G curved bar; gauge and length decide, not the word in the title.

FAQ

Because the piercing is a short, shallow channel through the outer third of the brow, and a gently bent bar follows that channel instead of fighting it. The balls sit flat above and below the brow, nothing sticks out to catch on towels or hair, and the piercing stays put. Piercers start eyebrows with a curved bar for exactly that reason.

16G is the eyebrow standard; 18G is finer and 14G suits fuller brows. Length is the distance between the balls: 5/16 inch (8mm) for a snug fit, 3/8 inch (10mm) for a thicker brow or a little swelling room. Too long flops and snags; too short pinches. Match the bar you wear now; every product page lists gauge and length.

Internally threaded and threadless bars are smooth where they pass through the skin, which is why piercers use them for new piercings; externally threaded bars carry their threads on the post end and are fine once you are healed. The product title tells you which. For a brow that is still settling, pick smooth.

Yes. A 16G curved barbell is the same jewelry whether the listing calls it an eyebrow ring, a rook barbell or vertical labret jewelry; we cross-list them so you do not miss a style. Match your gauge and length and it works in any of them. Daith and rook often take the 5/16 inch; vertical labret usually takes 5/16 or 3/8.

Unscrew the top ball, slide the bar in from below following the curve of the brow, then screw the ball back on with dry fingers until it is snug, not cranked. Give the top ball a gentle righty-tighty check in the mirror every few days; eyebrows are the piercing people lose balls from, because the bar is right where you rub your face.

3mm is the classic on a 16G bar; 4mm reads bolder and gem ends run a touch larger. Smaller sits flatter under glasses. If you lose one, the bar is still yours: spare balls are inexpensive and most 16G ends interchange within the same threading.
