Ear piercings heal quickly and comfortably when a captive bead ring is
worn. Rings are easier to clean and more comfortable than ear
piercing studs. Piercing studs are usually only one length which is
too short to accommodate swelling or earlobes which are thicker than
average. The butterfly clip backing can become clogged with discharge,
dirt, and bacteria. Studs also have a tendency to become wrapped with
hair, embedding hair in the piercing.
Please refer to Part 3 of the Piercing FAQ for information about the
piercing gun and needle piercing procedures.
Initial jewelry: Captive bead rings in 18 to 8 gauge and 3/8" to 5/8"
in diameter. The ring must not hug the edge of the earlobe. A ring
which is too small in diameter will cause the piercing to migrate or
scar. Heavy rings should not be used if the earlobe is exceptionally
thin. Straight barbells in 18 to 8 gauge and 1/4" to 5/16" long; the
length should be 1/16" longer than the width of the piercing to
accommodate swelling.
