when i was younger, my mom had the most beautiful long nails. she still does, i always had the "bite the nails" prolem, so lastnight i asked her how she did it. she told me to take gelatin capsules (as listed above by someone else.) and also to use that witchcraft nail strengthener each week.

Eat more protien. I started a high protien and low refined carb type diet and my once weak, short finger nails are growing like gangbusters. They are also stronger. I also keep a nail hardener on them, like Sally Hansen or just generic.

I am a nail tech, and agree the with the person that suggested Rejuvacote. I swear by it! However, use it as directed. Over using can cause nails to be too brittle and they will break. Also, when your nails seem to be healthy enough, you can start using it just a couple times a week. Also, Using cuticle oil or even olive oil is great to use evry night before bed. It keeps your cuicles soft and your nails hydrated. Women that have artificial nails should do the same so the natural nail underneath doesn't start to dry up and curl away from the tip.

eat lots of jello... it's good for your joints too

i dont know

At some beauty suppy stores sell nail growth formula. It may look weird when it dries, but from my own experiance it works. JUST TRY IT!!!! If it you dont think it works the way you want it to then just refund it (if your close beauty supply store does refunds)

If you take pre-natal vitamins they'll make your nails grow faster and become less brittle. You can take them whether you're pregnant or not.

always use hand lotion, NEVER EVER chew on them, dont file the sides, dont file them to a point, put a base coat on , and at least two coats of paint, and when they get long enough- paint the undersides of them - i have beautiful long nails and get compliments all the time and i have never been to a nail salon

use nail hardener...pregancy...or lots of sun will help!!! or have fake nails on (will stop u from biting them and will stop them form braking whilst they are growing)then in a month or so wen u take them of have them manicured then keep them in good condition!! hold it..x
