Chillz’s hair is commonly referred to as Choso Hair in Roblox, based on avatar-related references and the catalog item name. The closest match I found is the Roblox accessory “Choso Hair”.

Quick Scoop

  • Name: Choso Hair
  • Type: Hair accessory in Roblox
  • Why people say this: It matches the style used in Chillz avatar setups shown in community content

Extra note

Some players may describe it more loosely as a black, slicked-back, or fluffy anime-style hair, but Choso Hair is the clearest matching Roblox name I found.
