If you caught J Balvin's Coachella performance, then you saw the rainbow, leopard-print design that was hand-painted onto his head. Janine Cortez Ker is the artist behind the Lisa Frank-inspired hairstyle. She creates psychedelic animal print buzz cuts. Her inspiration comes from '90s and '70s punk rock culture. Cortez Ker starts with a clean buzz cut and bleach, then moves on to hair dye. She paints on leopard print, snake print, zebra print, floral prints, and more.
