Full Answer

Scientific American explains that loss of hair color does not indicate the presence of a health problem. Instead, the pigment known as melanin simply stops entering hair cells with age. Some people even experience this phenomenon very young in life. While genetic factors play a role in the process, as of 2014, researchers are still trying to understand the specifics behind the loss of pigmentation in the hair. The only difference between white and gray hair is simply that white hair has no pigmentation whatsoever, while gray hair still has traces of melanin.

    Is a natural white streak in hair something to worry about?

    A:

    A natural white streak that occurs in the hair is known as poliosis, and if it was present at birth, chances are it is nothing to worry about; however, if it was acquired later in life, it could be the symptom of an underlying medical condition.
