My last manicure was on April 18. Only my left thumb now shows any sign of that. Still, I find myself unable to give it up and bust out the nail polish remover. That thumb is so damned perfect, it seems a shame to erase all traces of its existence. (My manicure only cost $20, from a salon in Beverly Hills whose name I have never known - it's three doors up from my eyebrow guru's place, though, and produces consistenly good results. They even fixed my thumb once, for free, when I jacked it up immediately after I walked out of their salon. A pedicure is $25, and mine is still going strong.)
So how do you extend the life of your manicure? I usually slap on another layer of top coat a couple of days after my salon visit, and employ all the usual tricks (using spoons to open cans of soda, ruining my teeth by using them to open shampoo bottles, etc), but there must be better tricks out there than that.
By the way, all you women (and men - I know you're out there) who can give yourselves the perfect French manicure? I hate you. But don't let that stop you from leaving your manicure life extension tips in the comments!
