I lost my fingernail yesterday - I had seen a light bruise on it a month or two back but I don't remember trapping it, hitting it or anything like that. Anyway, my friend (a nail tech) said I'd probably lose it so I kept it as dry as possible, protected with a plaster etc to help the nail underneath to grow but finally yesterday it came off. 
Anyway, apart from a MASSIVE ridge as you'll see in the photos, it feels fine. It's quite hard on the top big bump and that feels like a normal nail but the bottom part nearer the fingertip is sensitive, more so after washing my hands etc (understandable really).
I just want to know if I need to keep it covered up or whether I can do anything to help it grow. I know it'll take a good few months to grow back properly but if I can strengthen it with any creams, that would be great to know.
Thanks in advance :)
