I absolutely ADORE this product! As the biggest GHD fan ever, I know how important it is to protect your hair from the heat, with irons reaching over 200 degrees. I've had great results using this spray. Firstly, you spray on a little and it makes a huge difference in making your hair smooth and silky. Hair glides easily through the hair iron after using this spray, and you can feel the difference immediately. I was stuck in a crazy rainstorm once (had straightened my hair that morning and used this protection spray). I went into the nearest bathroom, put my head under a hand dryer and brushed it dry - no frizz, almost back to perfect! This spray really works wonders. It's also light, doesn't make your hair greasy, and smells delicious. Worth every cent!
