Can you pierce your eyebrow with a 22-23 gauge needle for a 18gauage hoopring?
I wouldn't recommend it. 22 gauge is smaller than 18. The
smaller the number, the larger the ring/needle. If you use an 18
gauge needle and then put a threaded 18 gauge ring in, you are
likely to have more pain. I would use a 16 gauge needle and then
put the 18 gauge ring. The threads won't tear the new flesh, and
you're less likely to chicken out because it hurts. Remember to
push the needle through with the jewelry, because if you take the
needle out, you'll lose the hole before the jewelry goes through.
But then again, you really ought to go to a professional.
