Hey, i currently have my tongue, lip, septum and 10mm and 3mm tunnels in my ears whch have all been fine. I seem to have problems with surface piercings i.e my belly button grew out very fast and scarred and so did my eyebrow which has left a horrid scar. Im not sure if the two are connected or not. I have also heard that having the eyebrow pierced with a smaller 1.2mm curved bar can help prevent it from growing out - as i say i have only heard this but maybe speak to your local piercer :)
