Moisturize to the max. Wear cotton gloves to bed. Another fan of petroleum jelly is skin-care specialist Lia Schorr, owner of Lia Schorr Skin Care Salon in New York City. She advises her clients to put a thick layer of petroleum jelly on their hands when getting ready for bed, then wear cotton gloves overnight. This is especially helpful in winter, when hands and nails dry out quickly.
Women love the way it makes their nails look.
Soak 'em in olive oil. Schorr recommends an oil treatment for dry nails. She has learned through years of experience that it's best to use a half-cup of warm olive oil and soak your hands for 15 to 30 minutes. Hydrate with bath-oil capsules. Dr. Abel also advises women with brittle nails to soak their hands in diluted bath oil for five minutes once a day.
