You wouldn't believe how many nail biters I get, probably about 70% of my work comes from biters. I must confess I am an intermitent nail biter/skin nibbler. I asked my mother, when did I started biting my nails? She told me it was literally as soon as my teeth came through when I was a baby. I suppose it was comforting when teething. The problem I have is, when I put my mind to it I can grow them long and the nails re-attach to the nail beds really well, but as soon as I break one, I automatically nibble without realising I am doing it. On several occasions as child I was taken to casualty with an infected finger due to nail biting, I bit them down to the quick. I am also a trained Stenographer and while working in Court I had to keep them short, if they were long they would slip on the keys. I haven't done any Court work for a few years now and my nails are better than ever, although I do have the occasional accidental nibble. What percentage of your business comes from nail biters? My advice is to wear the enhancements for as long as they can, until they have a bit of length on the natural nail, when they stick the yukky finger into their mouth for a nibble, they realise there is nail there, and hopefully they won't do it. What advice do you give a biter?
