Elle Macpherson relies on her hair to keep her looking young rather than make-up.
The 50-year-old model is known for flawless complexion, which is highlighted by her luscious blonde locks. Elle believes maintaining the colour of her hair is what makes the most difference to her looks.
"My biggest beauty secret... choosing the right hair colour and keeping it maintained has the biggest effect on my skintone, more so than make-up," she told British magazine Look. "If my hair's a bit off, I can look drained, older, or tired. I tend to go for caramel lowlights in the summer and mink shades in the winter."
The Australian fashionista is set to launch her own body tonic called The Super Elixir, which can be added to meals such as smoothies and salads to improve how your body functions. Along with relying on this Elle also makes sure to regularly exercise in order to keep in shape and feeling good.
"If I'm staying in a hotel, I like going out for a run to explore," she added. "Cycling's exhilarating too; it's hard work going up hills and scary coming down! I want to do more yoga, as well."
On top of these tips, Elle often speaks about a piece of valuable advice her mom Frances passed down to her.
"The best tip my mom gave me [was] never say no to water," she shared. "I consciously drink about three litres every day (I decant it into six 50ml bottles the night before to make it more manageable). It has a huge impact on the texture of my skin and hair."
