You'll never bite your nails again.
Apart from tasting really disgusting, Anti-bite repairs your nails, linking protein molecules in your nail. If possible, use in conjunction with Acetone Free Nail polish Remover, Cuticle Balsam and Nail Magic.
Often the cuticles of a nail biter are either non-existent or in a bad condition. Damage from biting nails may even distort the shape of your nail but Trind's Nail magic, Anti-Bite and Cuticle Balsam will greatly assist to improve the shape.
It won't happen over night, you need to exercise a little patience.
