The only thing that works in my experience is milk...drinking lots of milk...
Agar koi baat bigar jaye...agar koi mushkil parjaye...
Tum dena saat mera...O Humnava
Na koi hai...na koi tha...zindagi mein tumhare siva...
Tum dena saat mera...O Humnava
Give your self manicures at least once a week. Use a strengthing nail polish remover with gelatin. Also Use a strengthner. Sally Hansen has some really good products. I use Diamond strength in Seal with a kiss, and than I use their Mega Shine as a top cost, which dries in one minutes and its very glossy. It helps protect my nails so they break less.
