The best looking Widow's Peak we've ever seen...

Widow's Peak

The Widow's Peak hairline is one of the best indicators of basic genetic inheritance. According to research by the University of Utah's Genetic Science Learning Center, only one of your parents has to have the dominant allele in order for you to inherit a Widow's Peak (or a lower, V-shaped hairline). So that means if mom is a Marilyn Monroe look-alike (whose gorgeous, long blonde locks also stemmed from a Widow's Peak) then you, too, will don this classic look.

But just think: If Leo DiCaprio and Blake Lively can work one, you can, too!
