At the time he was working for WWE, and he engaged in a mini feud with Chris Jericho, which culminated in the two competing in a hair versus hair match, with the loser having their long locks cut off by the victor. Nash tipped off that he would lose the match prior to the start by having his brunette hair already bleached blonde to match the Russian's look.
