Soak nails in olive oil
For weak, thin nails, soak them in extra virgin olive oil 10-15 minutes a day for a month, then twice a week thereafter. This inexpensive home beauty treatment will help fortify damaged, weak or peeling nails.

Use a cuticle cream
A soothing cuticle cream like Burt's Bees Lemon Butter Cuticle Creme helps nourish dry cuticles and brittle, damaged nails with vitamin E. Massage the cream into and around your nails nightly before going to bed.

Wear gloves for chores
When doing the dishes, cleaning and gardening, wear gloves. Detergents and cleansers are harsh on your fingernails, causing drying, spitting and peeling. Soil and gardening can also cause damage to your nails.

Find a miracle treatment
Sally Hansen Miracle Cure for Severe Problem Nails works wonders. It stops nails from peeling almost overnight. Using a mineral rich formula with protein and antioxidants, this treatment helps restore dry, splitting, damaged nails. A clear coat of nail polish may also help protect nails.

Eat biotin-rich foods
Make sure your diet features foods rich in biotin, such as liver, cooked eggs, whole grains, cauliflower and avocado, among others. In addition to other health benefits, biotin can help strengthen and thicken nails. You can also take a biotin supplement, if necessary.

Don't overuse your nails
Your fingernails aren't intended to be tools to open soda cans, dial the phone and other tasks. Instead, use a pen or other object rather than your fingernails to do these everyday tasks.
