Mere days after she wrapped Dying for Sex, Jenny Slate chopped off all her hair.

She’d had basically the same style all her adult life, but through the process of filming the FX cancer comedy, her locks began to take on new meaning. “I felt that my long hair held the sadness, and I just needed to reboot my physicality,” she says, explaining how she got what was left of her character out of her head. “Usually an extreme haircut means, ‘Oh hey, looks like you’re getting divorced!’ ” she notes. “But this was the first time I’ve changed my appearance because something good happened to me.”

And really, Dying for Sex should be very good to, and for, Jenny Slate. It’s the sort of sure-to-get-noticed prestige limited series — debuting April 4 — that can potentially alter an actor’s career trajectory. Not that Slate, 42, needs much of a course correction.
