I've done both I don't mind my eyes shave my eyebrow for no damn reason just for fun and it was really cool actually and I rocked it so I wouldn't mind being eyebrow this but nails did
That's not even comparable I can draw an eyebrow on with make up and shit but if I lose my nails that hurts plus I'm losing my toenails to wear fucking socks all day you out no no thank you
Honestly I can lose either or and be cool with it because if I lose my nails acrylics if I lose my eyebrow makeup is that serious or one of those tattoo eyebrow things
