It happens to the best of us, we get our nails to the desired length, smile with glee, then bam! the next day one of them has a slight break to it. You try to ignore it and leave it alone but any little thing you do, your broken nails gets caught. What choice are we left except to cut it to the stub and start over? Well I have a quick fix for you.
Start of with a buffer and buff the cracked part of your nail until it is smooth. Apply nail glue to the crack section and then apply a small piece of fabric, something like gauze from a band-aid. Place the fabric on the cracked part of your nail but make sure it isn't over lapping the top of your nail. Drench the fabric in more nail glue. Wrap the fabric around the cracked part, think of it like actually applying a band-aid and let the glue dry.
After the glue dries, start buffing the fabric. You want to make sure you buff all the hard edges first and then continue onto buffing the top of the fabric. Make sure the fabric is smooth and wash your hands. Apply, yes you guess it, more nail glue and let it dry. Repeat the buffing process and your nail band-aid should be smooth. Now you can apply a base coat, make sure you do this because it actually protects your nails, I like Essie. After the base coat dries you will see a little mark that looks like a band-aid. Now go ahead and apply your normal nail color and you are set to go!
This may seem like a lot of work but trust me when I say it is worth it. You can buy all the products mentioned at your local drug store and the whole process, including painting your nails, should only take about 30 minutes. Good luck!
