Nail ridges can be an annoying nail problem for otherwise perfect nails. Once they first appear, it can be very difficult if not impossible to get rid of them. We are born with smooth nails, but over time, faint ridges can appear; and in later years they can become more pronounced.
Nail ridges run the length of nails or across them and, if you are really unlucky, in both directions. The vertical ridges are typically the result of poor diet or aging; whereas horizontal ridges more commonly are found after frequently wearing nail products such as nail polish. Either the chemicals in nail polish or nail polish remover can be too strong for a sensitive nail bed and leave a slight scaring or ridge.
