i would actually suggest trying a titanium curved bar w/ smaller balls - maybe 5/32" balls.
I really think a bar will do much better than putting in a ring.
you can check online for something like that or we could order one in for you (we don't typically carry titanium curved bars).
if you'd like us to order one for you - please stop by the shop and we'll write up an order for it. I believe they're @ $20ish + tax (like i said - we don't typically carry titanium curved bars for hood piercings - so i'm not sure of the exact price).
we'll also want to know the length of bar you'll need - typically it's either 3/8" or 7/16". if you're not sure of the length we can measure what you've got in.
