I recently bought some of that Hoof Lacquer topcoat which is supposed to strengthen nails. For a couple of weeks, I just wore my nails bare with just a few coats of the stuff. They grew like weeds... but they turned yellow! Any suggestions on how to get them back to normal? I removed the lacquer right away, but they're still a pukey, unhealthy color, and I want to get them back to normal before I paint them again... Help, please!
