One of my nails is growing a vertical split from where it’s been filed too thin by a nail drill. I’m keeping my nails very short and filing them as smooth as possible to prevent catches, but the split on my index finger keeps growing as the nail is so thin and weak. Would it be advisable to use gel polish on top to strengthen and protect it until it’s grown out? Or is there something else I can do to protect it? Been using OPI nail envy and keeping covered with a plaster but the split is still growing due to daily activities putting pressure on the end of the nail
