Temporary dye?
Dreadlock Styles and Dread Styling
Greek mythology is complicated, theatrical and bloody, I can't help but love it.
Not sure if I'll go for a sexy Medusa, I'm trying to stand out from the crowd of semi-naked fairies and referees and Bo-Peeps and whatnot.
But yeah, green wires, fabric and hemp should do it! I'll be sure to post pictures, thanks everyone!
Also, maybe a lovely neck wound to allude to her beheading?
