Dont overdo hand washing and limit contact with cleaning chemicals

As healthy as it can be to wash your hands frequently, overdo it and you ll wreak havoc with your nails, says Stern. If you are in a profession where frequent hand washing is mandatory, she advises to use moisturizer as often as possible and rub a little extra around the cuticles several times a day. When doing housework or laundry, Jamal says, minimize contact with harsh chemicals, including dishwashing liquid, by wearing rubber gloves whenever possible.
