Years of running (and, I admit, neglect) have had a toll on my toe nails. I nearly always have a black one in the process of falling off. they are flakey yet tough. and my skin is dry. not a pretty picture. I find that a good coat of a dark colour conceals most of this (at least from a distance). but I'm starting to wonder if it's worth getting them done professionally...so...will a pedicure cope with my neglected nails? and how long will it last? any views on whether it's worth the time and money much appreciated.
