Hangnails are painful and can easily get infected. Many people bite them or pull them off. They usually come off attached to a piece of healthy skin, and this small wound is an open door to harmful bacteria.
Hangnails usually form when the skin is allowed to dry, and you can prevent this by keeping your hands and feet properly hydrated.
There are many cuticle creams in the market to help you keep your skin hydrated, but this is a cheap and effective way to keep hangnails at bay.
Work a little Vaseline petroleum jelly into the cuticles twice a day. You will never have to worry about hangnails again.
