Retrieving a sprite as a variable?

[Makusugi]

Hi, so my character sprites have the hair included already on them, they are all the same body & head just with different hair.

 

What I want to do is on character creation & first login it stores which sprite you picked in the character creator & then have it so whenever you equip a helmet to swap to a bald sprite secretly to hide the hair for the paperdoll & then when they unequip the helmet it would revert them back to their original stored sprite from the variable. 

 

I'm pretty new to events but I did get a set respawn point event working; can anyone walk a dumby through how to achieve this? Thanks!
