100% this, I feel like people don’t remember that he literally BEGGED them not to cut his hair, and the only reason it’s short in Infinity War is because it took place mere moments after Ragnarok. In Endgame he grew it out again and kept it long in Love and Thunder
Love and thunder was awful for thor’s character but at least it let him have long hair. He values his hair WHY would he willingly get it cut again
