Jennifer Aniston uses sweat to style her hair. The 'Cake' star believes perspiration is a great tool for styling your locks and uses it as though it was "product". When asked if she washes her hair after workouts, she said: "No, I don't. I actually don't. A little sweat in the hair is nice. It's like a little product. You just blow it out with your fingers and it's actually just fun." The star has insisted she only washes her hair every two or three days thanks to a shampooing product - made by a company she partly owns - which contains no silicone. She added to Fashionista magazine: "Silicone is a culprit in most shampoos. Over time, it builds up and turns into a hard coating and it cracks and breaks and snaps your hair.”
