Must one have Dreads to be Rasta?

Morgan Heritage’s song, ‘You don’t haffi dread to be Rasta’ intensely explains this perception. There is a common belief that if one wears dreadlocks then there is no doubt that they are Rastafarians.Could that be really the case? Does one’s hair define them? Or, is it a prerequisite for Rastafarians to grow dreadlocks or can you be one without them?
