I'm going on holiday in 3 weeks, will have the opportunity for a posh manicure while there but my hands and nails have been wrecked by the winter cold and weak nails which I've been biting (After 20 years of biting continuously, I now periodically grow then bite them - never quite stopped fully)
What can ISO to sort out my dry, rough skin that is a bit split around the nails? And how can I strengthen my nails so I'm less inclined to bite/pick them.
I want this manicure opportunity to not be wasted on rubbish hands!
