The Mamma Mia! actress says the secret to her luscious blonde locks is not over-styling them and will only use shampoo and conditioner every three days.
She said: “Don’t wash it! I wash my hair every three days which is something I would’ve never imagined years ago, but I also use dry shampoo and my hair is even healthier.”
Amanda also revealed how she takes good care of her skin and tries to protect herself from the sun as much as possible.
She told Stylelist: “I’m really scared of the sun. During the day, I use the Gentle Protective Emulsion moisturiser with SPF. And I don’t go to bed without putting on La Creme. It smells really good and when I wake up, I know my face is going to feel really good.”
Amanda recently revealed she is becoming more aware with how she’s ageing, saying: “Living in a society where there’s so much attention given to age-defying products, I’m really aware of how my face is changing, even at my age.”
