Anecdotes of such a connection are also visible throughout history: according to legend, the hair of Marie Antoinette, the 18th-century queen of France, turned white overnight just before her execution at the guillotine. In a small subset of participants, the researchers pinpointed segments in single hairs where color changes occurred in the pigmentation patterns. Then they calculated the times when the change happened using the known average growth rate of human hair: approximately one centimeter per month.

These participants also provided a history of the most stressful events they had experienced over the course of a year. This analysis revealed that the times when graying or reversal occurred corresponded to periods of significant stress or relaxation. In one individual, a year-old man with auburn hair, five strands of hair underwent graying reversal during the same time span, which coincided with a two-week vacation.

Another subject, a year-old woman with black hair, had one strand that contained a white segment that corresponded to two months during which she underwent marital separation and relocation—her highest-stress period in the year. For now, the next step is to look more carefully at the link between stress and graying.

While reducing stress in your life is always a smart move, the researchers say that the effects on hair color are sporadic and temporary, since stress is only one factor among many that influence the age-related breakdown of cells. However, the new study could have much broader implications.
