Hairstyle changing

[MotherDuck]

I just picked my first hairstyle but afterward changed my mind. But when I click the other available hairstyle, i go back to the other one the moment i leave the building.

help?

You probably don't have that hairstyle unlocked, so you can only wear it while in the shop.

Additional hairstyles are unlocked as rewards from spirits on the constellation platform (where you appear when you teleport home).

Make sure you have the hair style unlocked from their respective spirit trees.

Some of the newbie hair style ended up available (shown as owned) in the choice but will not work properly unless you actually unlocked them from their spirit trees. It's a known bug for ages.

The seasonal and event items will be available there for you to "preview" on your character, but will not stay and revert as soon as you left the changing altar or the shop area. They should show up in a slightly different color in the icon from the actual stuffs you owned.
