If you're using a new brand or color, place a small amount on one nail one day before you polish all your nails. If you have no reaction, it is safe to continue using that color. Hypoallergenic polishes are available from several manufacturers. Allergic reactions may also result from the use of artificial nails. It's usually the glues used to attach the artificial nail that are responsible for this reaction.
Artificial nails are most useful in cases where a toenail has been damaged or surgically removed.
But you'll have to give them the same type of attention you give your halt hands, and face. Get into a daily regimen and your feet will look and feel better. Start by soaking your feet in warm water for about five minutes. You may do this in your bath or in a separate tub. If your skin is dry add some bath oil to the water.
