"What's your name, my dear?" Loki asked the brunette who had spoken up.
Suddenly feeling shy with everyone's eyes glaring at her, she stuttered, "E- Emily."
"Okay, Emily," said Loki, "I'm going to be nice and give you shorter hair than the rest of your female classmates -- say, only about a foot long. How does that sound?"
A foot sounded like it would come out as a decent shoulder-length. Emily breathed a sigh of relief and said, "Sure, sounds great!"
"You asked for it," said Loki, pointing a finger in her direction. Emily instantly felt the bizarre sensation of hair retracting into her head. It zoomed upward, growing shorter and shorter, and it wasn't until it got to be shorter than a foot that she thought something might be wrong.
For a few seconds, those around her saw her resemble a cue ball, her head completely bald. Then hair exploded outward, almost instantly growing to its one-foot length -- however, it had exploded upward, and only down the middle of her scalp.
Emily could feel cool air on the sides of her scalp. One of her shocked classmates wordlessly gave her a hand mirror as Loki said, "There you go. Now, I shouldn't have to tell you this is permanent -- any effort to alter the style or the length, or even cover it with a hat, will be unsuccessful." Emily could only stare in the mirror at the Mohawk she'd apparently have for the rest of her life.
Loki turned his attention back to the class at large. "Since that was the second time I was interrupted, and the second time by one of you ladies, I'm sorry, but I'm just going to have to make things more interesting for all the females."
A collective shudder went through the hushed crowd, now that they'd seen several examples of Loki's "interesting."
"Your hair comes in all the colors," Loki simply said.
A lucky few girls got to keep their blonde, brown, or black color (including Emily), but all the other females in the room had their long, beautiful hair instantly change to a shade not found in nature. About two-thirds wound up with bright, vivid colors -- orange, fuchsia, turquoise, fluorescent purple. The other third got muted pastels -- robin's-egg blue, dusky pink, mint green.
Girls were taking strands of their hair in their hands to check the color and looking dismayed as Loki told them what they already suspected: "You'll find dye or any other method of trying to change the color to be completely ineffective. Oh, and I'll make things more interesting for your descendants, too -- your hair color is a highly dominant gene, so it'll be passed down to your female children, and their female children, and so on."
Loki looked over at the group of Goths. They actually looked happy, examining the girls' new hair colors, appearing impressed to see that they went all the way to the root. He waved an arm to indicate them to the rest of the promgoers. "It's nice to see that some of you are enjoying my transformations. They don't seem to mind what I'm doing."
"They're freaks!" came a male voice from somewhere in the crowd. Many people gasped, and a few turned, but not enough for Loki to single out the offender. He just smiled once again and said, "So obviously you want me to make it so they're less freaky."
