Barber chair

The barber chair is a constructible settlement item added in the Fallout 4 add-on Vault-Tec Workshop.

Description
The barber chair can be built in any settlement. Once a settler is assigned, the Sole Survivor can use it to change their hairstyle without needing to go to an already existing barber, like in Diamond City. All sessions are free of charge and give a Charisma boost that will last until overwritten with a different boost.

Crafting
The barber chair can be located in the build menu under "resources" and then under miscellaneous."

Behind the scenes
Early descriptions of the add-on implied that barber chairs could also be used to change the hairstyles of other settlers (similar to barbershops in Fallout Shelter). However, this was omitted from the released version of the add-on for undisclosed reasons.
