#1 Kurt Angle
Up until 2002, Kurt Angle and Edge were friends. However, the pair began to become rivals after WrestleMania 18, when Angle was insisting that he was the best that there was in WWE.
Angle lost to former ally Edge, which built tension between the two of them. The pair faced off in a series of matches, both coming off strong - something which infuriated Angle. To settle the matter, the pair were booked into a Hair versus Hair match at the 2002 installment of WWE Judgement Day.

During their match, Edge managed to work his way out of an Angle Lock to be able to pin the Olympic Hero. The Rated-R Superstar emerged as the winner, having the honour of shaving the head of his rival. Edge used the clippers on Angle on the ramp, while a barber watched on.
After this, Angle wore a wig on TV for a while. The wigs that he wore were terrible and often held to his head with a piece of wrestling headgear. As a short-lived skit, Angle's opponents would often try and remove his wig, before the bald look was embraced by the Olympic Hero on WWE television.
