This usually works for me, but when I recently split my nail vertically (OUCH!) I had to put in a little more effort. I found a technique to deal with broken nails that I thought might me helpful so I'm sharing.
I accidentally sliced my fingernail with a razor in the shower and the cut ran a little high for my liking (so not only am I adept at scratching myself, I can also slice!). I was determined not to cut it super short because that hurts and it looks weird and I had already suffered, so I found this sort of strange, but helpful method:
WHAT YOU NEED
HOW TO DO IT
1. Cut a small piece of the coffee filter and measure against your nail.
Trim to fit the width of your nail (you can trim length later).
2. Apply nail glue to your nail and lay the coffee filter op top. Trim the length of the filter if needed and then cover it with another layer of nail glue. Let dry and file it gently to smooth.
3. Cover the entire nail in top coat. When dry, finish with nail polish and another layer of top coat as normal.
Do you have any nail horror stories? Gross details are fine with me ;)
