The actress, who plays Princess Aurora in the movie sequel Maleficent, insists soft bedding is vital because it's so gentle on hair and skin.

Sharing her number one beauty secret, she says, "I swear by silk pillowcases. They're great for my hair and skin. I think everyone needs one. Plus, I sleep with conditioner in my hair once a week, it's not comfortable but I do it for the health of my hair, which is blonde and prone to breakage."

The star says people don't always realise she has a "natural curl" to her hair and when she isn't working, she rarely does anything to style her locks. 

"A lot of people don't realise as it's usually poker straight, but my hair has a natural curl. I don't wash it everyday and unless I'm going to an event, I just leave it in its natural state. If it's a really bad hair day I'll whip it up into a messy bun - but that's my go-to off-duty look," she tells Britain's Glamour Magazine.

Silk/satin pillowcases are celebrated for how they aid the maintenance of healthy hair. Firstly, using a silk pillowcase can help prevent hair from tangling while you sleep, and minimising knots. Secondly, silk pillowcases don't absorb moisture like cotton pillowcases do, resulting in them being less drying to your hair.
