I'm updating my OC Inferno!

I've had this character for a while. 1st she was an arsonist with basically the same story as Jeff the Killer, then I decided to make her into a proxy of Zalgo where she was half demon, and then I decided to make her like a fire warlock for some reason, and now I've decided to make her human again and give her a way better backstory. I'm also going to be adding a scar to her so there will be a redesign of her coming soon. Should I give her back her original red hair or should I keep it blonde?
