Premature white hair, scientifically known as "poliosis," refers to the development of white or gray hair at an early age, often before the age of 20. While it can affect individuals of any age, it is most commonly observed in adolescence. In the specific case of "white hair at 16," it implies the presence of noticeably white hair strands in a 16-year-old individual.
The emergence of white hair at a young age can have various causes. One common factor is genetics, as certain genetic traits can predispose individuals to premature hair graying. Other potential causes include underlying medical conditions, such as vitiligo or alopecia areata, which can affect hair pigmentation. Additionally, certain lifestyle factors, such as chronic stress or nutritional deficiencies, may also contribute to early hair graying.
