Someone at work was giving this away so I snatched it up. I spray a light mist over my towel-dried hair and then blow dry and flat iron. I use it in conjunction with the root spray on my roots for volume and I find the balance is perfect - the roots of my hair are fuller, and the ends of my hair don't appear less dry and damaged. I used to use another salon brand of heat protection products but since switching to Pureology I don't think I will go back. They are light weight and don't weigh my hair down.
