According to a survey reported in The Sun, demand for the One Direction star's barnet have jumped up 75% this year, toppling Justin Bieber as the most popular hair icon for British men.
Bieber's distinctive locks slipped to number three in the poll, while David Beckham's quiff came in at number two.
Presenter George Lamb's cut came in fourth, while Mark Ronson's hair rounded out the top five.
Commenting on the survey, stylist Andrea Daley, from Liverpool's Barbara Daley salon, said: "Harry's recognised what hair has done for Justin Bieber's career and wants his locks to help him be just as popular."
Other male stars to reach the top ten included Burberry model Eddie Redmayne, Daniel Craig, Gary Barlow, football pundit Jamie Redknapp and Leonardo DiCaprio.
