Katherine Heigl Explains Why She Changed Her Hair Color for 'Firefly Lane' Series

Katherine Heigl is opening up about going brunette for her new series Firefly Lane, which is streaming now on Netflix!

The 42-year-old former Grey’s Anatomy actress appeared on The Talk on Thursday (February 4) to talk about the new show.

“I just think this story is so beautiful, powerful, relatable and I haven’t had the opportunity to tell this kind of story [in] a long time. I just love and really respond to those really human, kind of relatable, heartwarming stories,” Katherine said. “I’m really proud how it turned out and I’m so proud of [co-star] Sarah Chalke, everyone involved in it.”

Katherine said she wanted to honor the source material, so she changed her hair color.

“In the book, Tully is a brunette so I love to honor the book as much as possible and I love changing my hair color…and that is very confusing for my children,” Katherine said. “My son, especially, who at the time was two, when I did it was just mind-blown. He didn’t even know who I was. Actually, I think he really loved the brunette. He’d kind of be like [face blushing], then I went back to blonde during the pandemic and he kept coming back to me like, ‘Where’s your brown hair?’”

Katherine recently reflected on leaving Grey’s Anatomy and what she regrets not doing sooner.
