Follow these steps in the game to get a faceless Avatar: Open the Avatar Editor in Roblox. Select Costumes and then Preset Costumes. Scroll down until you see the Man package. Next, choose it to open. Don’t forget to choose the Man Head. Visit Body > Scale, and then select the R6 body type.

While not faceless, you can go headless for free (without spending any Robux at all) by following a glitch/exploit. It’s not going to ban your account because it does not fall under cheating, but you do have to make some changes in file locations.
