I have week nails... what can I do to cure it?
They broke very offen...

Get a bottle of Biotin pills from the vitamin section of a pharmacy or *Mart type store. It helps make the nails softer. Follow the instructions, usually one or two per day. It is a common cosmetic secret which does help.

I agree with the post above, as well as getting just a simple nail strengthner that you should be able to get anywhere that nail polish is sold && applying it every day. I used to have weak, brittle nails, && the strengthner did wonders.
