Great advice for girls who used to wear long nails. Even if you have a cracked nail, it is not necessary to cut off!
The solution is very simple. Take an empty tea bag, crops it to a small square. Now apply on a regular basis under the nail polish (you can replace it with a clear varnish). While the foundation is still wet, apply to the site of fracture piece tea bag. At the end of the cut nails another base layer.
Done! Now you can apply your favorite nail color!
