Prince Harry has topped a poll for having the sexiest beard ahead of David Beckham, Bradley Cooper and Ryan Gosling, according to a study carried out by Crown Clinic.

The 33-year-old royal has been named the man with the best facial hair in a survey carried out by Crown Clinic in Manchester, which is Britain's leading hair transplant centre.

And the outcome of the study has shown Harry - who is currently dating 'Suits' actress Meghan Markle - has been hailed a "trendsetter" as he has made the biggest impression on the public with his stubble, beating 'La La Land' actor Ryan Gosling to the hot spot.

The Crown Clinic surgeon, Asim Shahmalak, said: "Prince Harry is a trendsetter for lots of men around the world and the reaction to his beard has been universally positive.

"While he looks great with his ginger fuzz, the sad fact is almost half the men in the UK cannot grow a full beard like Harry."

Harry has also pipped 42-year-old actor Bradley Cooper to the number one position, as the 'American Sniper' hunk has been ranked in third place, below the 36-year-old 'The Notebook' heartthrob. 

The study has even ranked footballers Harry Kane, 24, and David Beckham, 42, - who previously claimed the title - in fourth and fifth place. 

However, the former England captain is ranked higher than 49-year-old actor Hugh Jackman, who is known for having a full face of hair for his role as the blade-yielding mutant Wolverine in 'The X-Men'.

However, 'Cry Me A River' hitmaker Justin Timberlake as well as actors Brad Pitt, Joaquin Phoenix and Jim Carrey didn't even make the top 10 best beards list and actually fell into the five worst beards category. 

As part of the study people also voted on how attractive they considered a male to be based on their appearance, and almost 40 per cent of women who carried out the poll think men are less appealing when they have a beard as 62 per cent of them prefer men to be clean shaven. 

The study has also found that almost 50 per cent of men struggle to grow facial hair at all.
