Keep nail beds hydrated

To keep your nails hydrated, rub a small amount of petroleum jelly into your cuticle and the skin surrounding your nails every evening before you go to bed or whenever your nails feel dry. Keep a jar in your bag, desk drawer, car – anywhere you might need it. Not a fan of petroleum jelly? Substitute castor oil. It’s thick and contains vitamin E, which is great for your cuticles. Or head to your kitchen cupboard and grab the olive oil – it also works to moisturise your nails.
Protect nails from wear and tear

Wear rubber gloves whenever you do housework or wash dishes. Most household chores from gardening, to scrubbing the bathroom, to washing dishes, are murderous on healthy nails. For extra hand softness, apply hand cream before you put on the rubber gloves. Slipping on some gloves will also protect your manicure.
Treat cuticles gently

When pushing back your cuticles (it is not necessary to cut them), come in at a 45-degree angle and be very gentle. Otherwise, the cuticle will become damaged, weakening the entire nail, says manicurist, Mariana Diaconescu.
