I'm going to assume that since you're searching for head enchants you're recently level 80 or working on getting there as the only one's worth getting are the ones at maximum level.
Discounting level 60 and level 70 as there really isn't a point in getting those, all helm or head enchants require a certain amount of reputation to purchase from a "Quartermaster".
In recent patches, head enchants requiring "Revered" can also pass it to another character on the same account and server.
All of these enchants require a minimum level of 80.
