The 24 year old Manchester United player has been noticeably balding since his teens.
According to tabloid reports, some of his team mates started calling him Bobby Charlton, the footballing legend famed for his combover.
Finasteride is no longer a banned substance under the World Anti-doping Agency and Rooney is believed to have started using it.
While it won't bring back his childhood head of hair, it should stabilise his hair loss enough to stop the Bobby Charlton jibes.
Incidentally Rooney has scored a lot of goals from headers this season, and recently said "I’m still working on my heading. But probably the goals are all coming off my bald patch! That’s helping me to score."
