5. Louis Gaudinot
Gaudinot first debuted his weird teal-colorer hair on the 14th season of the Ultimate Fighter.
He might wish that he spent less time on his hair and more time training however, as his UFC career was less than impressive. Gaudinot racked up a 1-3-1 record in the promotion, though he did manage a victory over John Lineker.
Gaudinot and his hair was released from the UFC in 2015, but is 2-0 since that time.
