Following her 2016 head injury, Hayley found that resting with citrine pieces on her forehead and using a citrine crystal was one of the few things that brought her relief, and she later named her next EP Citrine. "I couldn't think, I couldn't open my eyes, I couldn't drive," she told Buzzfeed in January 2018 about the aftermath of her accident. "I was f*cked up. I take like five pills a day for my head, still."
