After seeing the wax statue, Ronaldo contacted the original artist, Michael Wade, to make another, according to Callum Davis of the UK Telegraph. Wade still had the original molds and was paid £20,000 (~$31,000) by Ronaldo for the statue.
The only difference between the original and the new statue is the uniform and shoes. Ronaldo sent the artist up-to-date versions of both.
Both statues also have real hair, added one strand a time. The statue at the Madrid museum is styled once a month by a stylist provided by Ronaldo to keep the hairstyle current. Presumably the same will be done with the statue in Ronaldo's home as Wade said he was told to add the hair but not to style it.
