How it works
It’s a common misconception that a particular dominant gene causes a widow’s peak. Like other traits that influence hair growth, various genes work together to help determine the shape of our hairlines. Some researchers believe that hair patterns are heritable, so a close relative with a widow’s peak may increase your chances of having this hairline, too.
The genetic link
Genetic markers in your DNA, along with age and sex, influence the chances that you will have a widow’s peak.
Did you know?
Most children have a smooth, flat hairline. As they age into adolescence and adulthood, their hairlines tend to move higher up the foreheads. The presence or absence of a widow’s peak is just another example of our diverse features. Age-related receding hairline patterns can also resemble widow’s peaks in both men and women.
