Nail problems solved

Yellow Nails
Yellowing of the nails could be caused by not using a base coat underneath your regular varnish, or it could be a more serious nail fungus that needs treatment. You can lighten discoloured nails with a whitening scrub containing a mild abrasive, or with a remover containing a lemon juice-like ingredient that bleaches out the yellow colour. Ask your local manicurist or chemist for product recommendations.

Nail Biting
Unfortunately, there is no easy solution to stop nail biting. One good way to try and stop, however, is to get a professional manicure each week or every other week. When your nails are nicely filed and varnished, you're less likely to bite them. And if your hands look beautiful you’re less likely to want to cover them up (as most nail biters tend do). If nail biting becomes a serious problem, you might want to consider artificial nails.
