Hi Maiko, hope you are doing good. Here, the best helmet enchantment you can try is to go for Protection. It is no doubt the finest enchantment for all armor in Minecraft, when it comes to protection. This enchantment has all of the best qualities of the other safety enchantments and has a maximum level of IV. As it is detailed protection that means that it safeguards from all kinds of damage that including lava, attacks, fire, and falling. Apart from that, it is less productive than the other enchantments, it deals with all of the protections at once because it is actually very helpful.
