My nails have always been weak, and probe to splitting and flaking at the ends, but have got noticeably worse since I had dd 3 years ago.
I've just come back from holiday, and had a manicure with shellac nails before I went and miraculously none have broken yet.
The shellac needs infilling, but I really can't afford it, is there something I can buy and apply myself that would have a similar effect?
