Player Valuation: £100m
This is off the FA website:Negligible is when the strike is with the hand or arm.
That isnt the case with headbutts - they're always violent conduct no matter how soft they are.
VIOLENT CONDUCT
Violent conduct is when a player uses or attempts to use excessive force or brutality against an opponent when not challenging for the ball, or against a team-mate, team official, match official, spectator or any other person, regardless of whether contact is made.
In addition, a player who, when not challenging for the ball, deliberately strikes an opponent or any other person on the head or face with the hand or arm, is guilty of violent conduct unless the force used was negligible.
It doesn't make any specific mention of a head butt being different so I guess it's a grey area but for me the same rules should be applied
