Prince Harry isn't expected to be crowned as King of United Kingdom as the sixth in line to the British throne. However, he is keeping watch over another crown -- the ginger mass of hair on his head. 

The Duke of Sussex is, reportedly, getting medical treatments for a family-inherited condition: hair loss. Sources revealed that Prince Harry is also struggling with this common adult male condition just like his older brother Prince William, his father Prince Charles, and his grandfather Prince Philip. 

Thus, he is undergoing a series of hair thickening treatments at a prestigious clinic in London, the Philip Kingsley Trichological Clinic. According to The Telegraph, the cost of the treatment is $5,200 (or £4,000).

The reports further cited that Prince Harry's hair has been progressively thinning since his marriage to Meghan Markle in 2018. Royal observers said that the bald spot on the back of his head has grown bigger in the last two years. 

Rumors have swirled that Prince Harry was considering an extensive procedure to treat his bald spot even before his wedding. Apparently, this condition can be reversed with consistent treatment.

It's unclear what particular hair loss treatment the Duke of Sussex is receiving at the specialized clinic but the Kingsley facility has a reputation for being one of the best places for hair loss treatments in the world. The center's clients are the rich, the famous and the well-connected just like the royal family. 

According to Page Six, Kingsley, who died in 2016, had a celebrated 65-year career as one of London's best hairdressers. He was labeled as "a true visionary in the world of hair care." 

Meanwhile, Prince Harry is reportedly set to return to London in March with Meghan and their son Archie. Their presence was requested by Queen Elizabeth for Commonwealth Day, where a service will be taking place at Westminster Abbey on March 9 with the royal family.

This return, however, will be part of the final round of official royal engagements for Prince Harry and Meghan. They Sussex royals are stepping down from their royal roles beginning spring after a series of talks with Her Majesty. They have also asked to spend half of their time in North America. 

According to People, Prince Harry and Meghan have been enjoying the quiet life in Canada since leaving London in January. They spend their time hiking and doing yoga while Meghan cooks for her family.
