This is approximately what Loki looked like the very first time He appeared in one of my dreams.
(I forgot the tunic was supposed to be pale yellow ^_^)
In the beginning Loki appeared with ash-blond hair in my dreams – I guess He knew I had a thing for blondes ^_^.
Then he began to appear with long blond and strawberry blond hair, either the bottom half red, or with red stripes. He went ginger a few times, and then He began to appear as a red head, with the occasional blond.
I like Him with both long and short, blond and red hair.
