The 46-year-old actress - who has children Sunday, five, and Faith, three, with 'American Idol' judge Keith Urban - has been taking Ultiboost vitamins for the last five years after suffering from hair loss and believes the hair, skin and nail supplements have transformed her locks and returned them to their former glory.

She told Britian's InStyle magazine: "I always take hair, skin and nail Ultiboost vitamins from a company called Swisse, which I'm the global ambassador for.

"I down them religiously and they've made my hair thicker. After I had my baby, my hair got so thin. I used to have really thick hair; now it has all come back."

The actress wore her flame-coloured locks in loose ringlets when she first broke into Hollywood, and is finally reverting back to her old look after years of straightening her hair.

She explained: "I almost never straighten it anymore, I let it go curly and wild. It's taken me 40-something years, but I embrace the curl. My littlest daughter has the same hair. She likes it when my hair is curly, so I wear it for her. "

Nicole finds it difficult to stick to a healthy diet when she's accompanying country music singer Keith on tour so makes up for it when she gets home.

The 'Grace of Monaco' star added: "I would never have junk food four or five days in a row. I try to balance it. If we have a bad few days on the bus, we'll come home and steam vegetables and eat salad and be good."
