Evangeline Lilly had to bleach her hair “every 10 days” to keep it naturally blonde

Evangeline Lilly explained everything she had to do to keep her hair blonde in the movie South of Heaven during an interview with People.

The actress, 42, said she needs to dye her hair every 10 days to keep her hair naturally blonde, rather than platinum blonde.

“I bleached my hair every 10 days and when we finished shooting it was falling out,” the Ant-Man star said.

Lilly said that she and South of Heaven director Aharon Keshales both wanted her character to look like “the sun and the source of life” in the movie.

“I chose for her to have naturally blonde hair and a warmer sort of complexion so that she was glowing, healthy, vibrant and full of life,” the Lost star said.

“But this interview got really tough because I wanted her to look like a natural blonde.”

She also took on the challenge of having her hair cut very short before filming began, a decision she made for fun and not for the character.
