Widow's peak
A V-shaped point in the hairline at the centre of the forehead.
Also: V-shaped hairline
A widow's peak is a downward point in the middle of the hairline. The name comes from the pointed hood once worn by widows in mourning in Britain, and an old superstition that the peak foretold early widowhood. It was long taught in schools as a simple dominant trait, but studies suggest its inheritance is more complex. It is found in people of every background and can become more visible as the hairline at the temples rises.
