I haven't seen her in anything else, so that's a good point; I actually have no idea what her hair's natural state is. It does look perm-y, but a few people actually have tight ringlets like that, so who knows. I assume that's her natural color, though, which is awesome on its own. Dyed red hair usually looks fake unless you have a celebrity-level colorist to dye it like six different shades for verisimilitude.

I used to try to straighten my own long hair, and it is an impossible task. Go Elena.

LOTS OF HAIR solidarity. I also have long hair, which is quite curly, and I can attest that trying to straighten it is just an exercise in futility. Fortunately I like the curls, but the only time my hair is straight is when I have a hairstylist to do it for me. Though to be fair, I have no hair skill whatsoever. Special events usually lead to me wrestling with my hair for 20 minutes, getting more and more frustrated, and then going "...I can probably get away with a ponytail."
