Hair Turning White Overnight

While stress may play a role in turning your hair gray, it cannot do it overnight. Marie Antoinette's and Sir Thomas More's hair were said to have turned completely white the night before they were behealed. Despite these and other historical anecdotes, no medical evidences exists that hair can turn white or gray so quickly. Once hair is produced in the hair follicles, individual hairs cannot change color. The root of these anecdotes may be  Diffuse Alopecia Areata, a condition that is sometimes triggered by stress and causes a lot of hair to fall out very quickly.
