  I do think that there is a type of divination that is based on reading the small white patches on one’s nail… but from a science point of view…
  
  According to the source listed below, these patches have all sorts of causes. They can be caused by injury (nail biting, day-to-day injuries, or shoes that are too small) to the part where the nail grows from, known as the matrix. This type of injury is common in children and is usually the cause of white spots on the nail.
  
  There is also some medication that can cause white patches, and lastly, there are some illnesses which can manifest with those patches also.
