Soccer legend David Beckham and Catherine, Duchess Of Cambridge have the perfect celebrity hairstyles of 2015, according to new research.
Former sportsman Beckham, crooner Michael Buble, and comedian Russell Brand are proof that men achieve the ideal look for their locks at the age of 39.
Women hit their hair peak at 32, as proved by the tumbling tresses and luscious locks of Prince William's wife Catherine, and Hollywood stars Anne Hathaway, Kirsten Dunst, and Jessica Biel.
Research by staff at the Crown Clinic in Manchester, Britain's leading hair transplant centre, also shows the average woman has tried almost 50 different styles before finding her ideal image, while most men go through 10 looks before settling on their best.
Crown Clinic hair transplant surgeon Asim Shahmalak says, "Kate's hair is admired by women all over the world. It has a wonderful lustrous quality to it and is styled perfectly. She is very comfortable with her style and it looks so right for a woman of 32.
"David Beckham is a style icon in so many ways - not least his hair. From his mohican cut, to his crew cut and now to his slick back parted style, he has always been a fashion leader. After many years of chopping and changing his hair, he seems to have arrived at a style he is happy with at 39."
