Heads are decorative blocks introduced in the highly anticipated Minecraft 1.4 update.
Although they may be technically considered to be decorative, they serve a purpose for single-player Minecraft.
Players’ heads are often used for Minecraft server servers as part of several server-side plugins.
In Minecraft, six kinds of heads are acquired. These are player zombies, skeletons withers, skeletons, creepers, and dragons.
Each head can be broken without the need for any special tools. They can be discarded when destroyed.

What exactly does a creeper head have to do?
Wearing a creeper’s head will reduce the range that the creeper will be able to see you by 50 percent.
The same concept applies to zombies and skeletons too, with zombie heads and skeleton heads as well.
Final Words
Heads are an attractive and unique decorative element in the game because they are smaller than standard blocks, and any texture can be added to the blocks.
Adventure map makers and servers on Minecraft specifically utilize the player head to their advantage because their textures can be modified to match real-world objects; this can effectively add new blocks that add interest for the player.
In a practical sense, however, players can put on specific mob heads that block particular mob detection areas, which makes the mob easier to fight and farm.
