When nails become dry, they are ridged, brittle.
It's not very pretty.
It is then necessary to nourish them in order to restore their smooth and shiny appearance naturally.
This remedy exists, it is Vaseline.
Quite simply.
1. Coat your nails with petroleum jelly every night.
2. Put on silk gloves to sleep.
And now, after a few days your nails are no longer brittle :-).
You can take the opportunity to coat your hands entirely with petroleum jelly. They will also become soft.
