The actress said of the news: “I’m so excited about being the new nice’n easy ambassador, it’s a product I’ve been using ever since I went red. I love that the results from nice’n easy are so natural looking; I know it’s going to turn out natural and beautiful and I don’t have to worry about it.
"People never believe that I do my hair colour myself at home. They say, ‘You don’t do your hair at home by yourself, do you?’ and I always reply and say ‘I honestly do!’ I like that I can trust the brand and product and that I can have it in my drawer at all times for when I need it.”
Hendricks is naturally a dark blonde but began dying her hair red as a young girl after she was inspired by the fictional heroine of LM Montgomery's books Anne of Green Gables.
Hendricks will promote the brand's 'Shift a Shade' campaign which encourages people to find a hair colour that is true to you, and so natural looking that no-one would know it wasn't the colour you were born with.
Nice’n easy Colour Advisor and celebrity stylist Jonathan Long said: “Shifting a shade doesn’t have to be a scary prospect – do as Christina did and find the shade that is true to you! nice’n easy have 56 shades in the range so there really is one for everyone to make that change and it will still look natural."
Hendricks' nice 'n easy shade is below, Natural Light Auburn, RRP €7.99.
