The concept of hair turning white due to fear is rooted in folklore and is not scientifically proven. Hair color is determined by the presence of pigments called melanin, which are produced by cells called melanocytes. The process of hair turning white is a natural part of the aging process as melanocytes gradually stop producing melanin. However, there is no scientific evidence to suggest that fear or any emotional state can directly cause melanocytes to stop producing melanin.
In extreme cases of stress, it is possible for hair to turn white, but this is not because of the fear itself. Instead, it is due to the body's physiological response to stress, which can affect various systems and processes, including the immune system. There have been anecdotal reports of individuals experiencing sudden whitening of hair following a severe shock or trauma, but these cases are rare and not well understood.
In summary, while it is a common trope in literature and storytelling, hair turning white from fear is not a scientifically recognized phenomenon. The change in hair color is more likely to be associated with the natural aging process or, in rare cases, a response to extreme stress.
