"Beware, forswear,
Replace the old
With brand new hair"
She uses magic. She doesn't consider another option. Before she even goes to the Isle, when she's putting on her old leathers and feeling slightly like herself again, she cast the spell, one she could cast in her sleep now, she thinks. And she doesn't even look, but she can feel what the spell does.
She can feel the new hair growing out, can feel the old hair disappearing, and she can feel the long tresses fall in curls down her back.
{She looks in the mirror, and an unnatural red looks back. Her hair is long, and the colour of blood, and completely new. She smirks and grabs her keys.}
