The main draw of Netflix‘s new show Maniac are the amazing dreamscapes, the bizarre and intricate worlds that Annie (Emma Stone) and Owen (Jonah Hill) experience after taking pills given to them during a pharmaceutical trial. The mind-bending adventures are sometimes based in real memories, other times pure fantasy—but each one takes the viewer into the deep recesses of Annie and Owen’s minds.
In other words, these dreamscapes are a visual feast chock full of easter eggs, surreal gags, and cool hair. No, really: Emma Stone’s hair journey is a fun trip in and of itself. So much so that I called the show’s hair department head Fríða Aradóttir to walk me through each look. “It felt like we were doing something different; that possibly wasn’t done in this format before,” she says of filming Maniac. “And that’s really, really exciting.” See her take on the hairstyles, below.
