As the title says, I've had several clients recently who have got unexplained white spots on their nails after Shellac removal. To begin with I thought this was dehydration but it doesn't disappear with solar oil. I know it isn't damage caused by rough removal as it mostly appears on nails where the shellac has lifted completely from the nail after the wrap is removed so I haven't touched the nail at all. I haven't encountered this before. Any suggestions lovely geeks?
