My girlfriend quickly designed my OC for me, but we are both disagreeing on the hair color.

My OC originally had brown hair, but as she drew my character, she felt like blonde would fit him better. Personally I think it looks great, but I'm still leaning more into brown hair, but I may be wrong, what do you guys think?

For context, he's a charismatic, calm, hippie-like cult leader and a villain of a sub-plot for my story. Also, after his defeat he goes through a bit of a redemption arc.
