Whatever the weather, keeping your hair straight and silky is now so much possibly with the discovery of hair products that banish frizz by Professor Robert Langer, of the Massachusetts Institute of Technology.

This latest amazing breakthrough is a spray and a cream, which shields each hair from the tiny drops of water that cause kinks and curls. Termed as one of the leading advances in the beauty world for three decades, unlike other products already available in the market, it claims to keep grease at bay, meaning, hair can be washed less often.

Professor Robert Langer was part of the team, who in the mid-90s productively grew an ear-shaped piece of cartilage for human transplant, by implanting a 'scaffold' on the back of a mouse.

For this new project, Professor Langer's team studied the straightening creams, sprays and gels that were already obtainable.

The product names are different, but they all use the same ingredient, Silicone. None is entirely effective and hair can be left feeling weighty and greasy.

Instead, the No Frizz range uses a man-made water and oil-repellent compound called polyfluoroester to coat the hair.

“Humidity is hair's number one enemy. It expands the hair shaft and that is why you get frizz. And the more damaged your hair is, the more porous. If you color treat or use heated appliances, it damages the hair and frizz is more of a problem”, Rob Robillard of Living Proof, the U.S. manufacturer of No Frizz said.

Bottles, which last from one to two months, cost £18.
