Gwyneth Paltrow gets greasy hair.
The 'Country Strong' actress always keeps a can of dry shampoo to hand to mop up excess oil from her roots and scalp, with a particular favourite being Klorane Gentle Dry Shampoo with Oatmilk.
Explaining why she likes the product, she wrote in her GOOP newsletter: "This stuff's great when your hair needs a little spiffing up, especially when it's starting to get a bit greasy.
"If you want to maintain a blow dry or don't have time to do a full wash and blow out, this really does the trick. It gets right to the roots and brings back volume and makes your hair less oily."
The 38-year-old star - who has children Apple, six, and Moses, four, with husband Chris Martin - is a particular fan of French beauty products and always makes sure she stocks up on her must have products when travelling through Europe.
She added: "Many of the absolute best beauty products I've found come from regular French pharmacies. I always stock up on these items when I'm in France or ask friends to bring some back when they're passing through."
