Jessica Chastain Hair Color FormulaWhat, you thought it was all natural? Jessica Chastain has gorgeous, poweful haircolor, courtesy Negin Zand of Salon Benjamin in West Hollywood, California. Negin is asked regularly for the formula, but she has decided to give it up to Modern! "Jessica is a natural redhead," she says, "So I just put a gloss on to enhance her natural color."

The formula is simple, all L'Oréal Professionnel DIA Light: 1/2 clear, 1/2 gold & copper.

"It offers intense shine and shimmer," she adds.
