1. Use moisturizer
When rubbing lotion or oil into your hands, make sure you work it into the cuticles and nails, too. Regular handwashing or use of hand sanitizer can dry out the skin and nail bed quickly, so try to moisturize after every wash, if possible. Coconut oil is excellent for rubbing into your nails and cuticles
2. Care for your cuticles
Avoid having your cuticles trimmed during a manicure. Cuticles are meant to be a barrier for bacteria, and cutting them can lead to painful infections. You can moisten and push them back with a cuticle pusher, and trim away only dead pieces of skin
3. Avoid using harsh polish
Nail polish typically contains very toxic chemicals such as toluene, dibutyl phthalate, dimethyl and diethyl phthalates, camphor, and formaldehyde. Fortunately, companies such as OPI, Orly, Sally Hansen, and Revlon make some polishes that do not contain these chemicals, but make sure you read the label carefully before purchasing. You can also buy water-based polishes, which don't last as long but are the safest option out there..
4-Eat well
Diet is very important to maintaining healthy nails. Protein is crucial, as are omega-3 fatty acids. Eating foods with vitamin B reduces brittleness; zinc gets rid of white spots; iron prevents ridges from forming; calcium keeps them strong; vitamins A and C prevents dullness and drying. Drink plenty of water to stay hydrate..
5-Make a natural nail-strengthening treatment-
Mix: 2 tsp castor oil, 2 tsp salt, 1 tsp wheat germ oil. Mix and keep in a sealed bottle. Rub a small amount onto your nails. Leave for 3 to 5 minutes. Wipe off. Makes enough for 20 to 30 applications....?????
