Can misshapen cuticles regain their natural shape?

[stickysteena]

I used to bite my nails when I was younger, but kicked the habit years ago. Until recently, my nails were lovely, but then work stress increased and I started to nibble my cuticles (and pick at them with my thumb). I'm in the process of curbing this habit (again) and have began to look after them (creams, oils etc). The thing is, I think I may have ruined their shape - I picked and nibbled so much that they seem wider than usual and funny shaped.

So...will they regain their shape given the chance (i.e. no nibbles and lookng after them) or have I ruined them completely?

I don't want a fast solution and know it may take time
