A widow's peak is a dominant physical trait where the hairline dips into a V-shape near the center of the forehead. The expression comes from the belief that it was a sign of early widowhood, though the trait has also been considered a mark of beauty.
In addition to ambiguities about who does or does not have a widow's peak, there is the problem of age. The hairline of many men recedes over time, and it often recedes more slowly in the middle. It could therefore be difficult to distinguish between a receding hairline and a true widow's peak in adult men.
