You may have seen reports recently about how Prince Harry is quitting the Army in June.
Harry said it was a 'really tough decision' but he was keen to work on new projects after his 10-year career in the military which has seen him bravely serving on the frontline in Afghanistan.
Harry is in many ways our most popular royal: fun-loving, always cheerful, he is a wonderful advert for the royal family.
He turned 30 last year and, while his hair loss is not nearly as pronounced as his older brother William, there is no doubt that his hair is starting to thin, particularly around the crown.
Dr Shahmalak said: "Harry is clearly showing the early stages of male pattern baldness around his crown. He would benefit from taking Finasteride - a clinically proven drug which should help to stop him losing more of his natural hair. Unfortunately, Finasteride won't help grow new hair for Harry but it will limit the spread of his baldness.
"If Harry continues to lose his hair at the current rate he will probably be in need of a hair transplant in a few years' time. He has a strong baldness gene running through his family on both his father and his mother's side.
"As for Prince William, I feel that it may be too late to help him to have a hair transplant. His male pattern baldness his fairly advanced and he would require multiple procedures to restore his lost hair."
