The idiom "a hot head" refers to someone who is easily angered or quick to become upset or frustrated. It implies that the person has a tendency to react emotionally or impulsively in challenging situations.
It can mean several things, depending on whether it is meant literally or as an idiom. Literally, it would mean that the tip of something is red-hot, or glowing with heat. As an idiom, a "tip" is information that can be used in a situation, so a "red-hot" one would be something that is especially important at the moment, something timely and greatly useful.
