There may be a lot of stress surrounding Prince Harry since his marriage to Meghan Markle, but despite some belief, the Duke of Sussex doesn’t need to blame his wife for his recent hair loss.

Royal fans have begun to notice that Prince Harry has started to form a spot on the back of his head where his hair has started to thin out, but a patient advisor on the subject warns that though stress about the negative press surrounding his wife could be a contributing factor, it isn’t the real reason he has started to lose some hair.

“Genetics is the cause of Harry’s hair loss,” Paul Oliver, a senior patient advisor at the Vinci Hair Clinic told Express UK. “I believe stress can be a contributing factor in causing it to begin sooner, but it would have occurred eventually.”

Oliver stated that Harry suffers from androgenetic alopecia, more commonly known as male pattern baldness, and it is something that runs in his family, as evidenced by Prince William and Prince Charles as well.

“Male pattern baldness, also known as androgenetic alopecia, is triggered by the genes passed from your father or either grandfather, two brothers can take these genes from different members of the family so will have differing amounts of loss,” Oliver said. “This could be the case for William and Harry.”

Though Harry used to joke about his brother’s losing his hair for years, it’s been noted since his marriage to Markle in May 2018 that his own hair loss has seemingly accelerated. While some likely would love to blame his wife, who has been hounded by negative press since the fall, it’s something that can be attributed to his genetics. His grandfather, Prince Philip, father, Prince Charles, and brother Prince William, all also have dealt with hair loss over the years. Williams even notably began seeing his hair thin out in his 20s, sporting an already somewhat receding hairline even at his own wedding to Kate Middleton in 2011. He was just 28 years old at the time.

However, if Markle is to blame in any light, it’s because he is doing less to hide it due to his being content with their relationship, according to Dr. Asim Shahmalak.

Shahmalak told The Daily Mail in November that the Prince’s happiness was evident in the fact that he wasn’t trying to keep his hair loss a secret.

“While marital happiness does not bring about any hormonal changes which would affect hair loss, research shows that men in settled relationships tend to do less to disguise their baldness,” he said at the time. “It reflects nature and the need to find a partner. Once that goal is achieved there is slightly less incentive to cover up hair loss.”
