Onychoschizia or splitting of the fingernails is one of the most common problems that a dermatologist sees. The term onychoschizia includes splitting, frail, soft or thin nails and nails with ridges, and is more common in women.

The best treatment for Onychoschizia is to avoid repeated wetting and drying of the nails. Try to wear cotton lined rubber gloves when performing household chores that involve getting the hands wet.

Some patients are convinced that one pack of Knox Gelatin mixed with orange juice taken by mouth each day will restore nails to a youthful state. There is no scientific data that supports the use of unflavored gelatin to strengthen nails.
