I had cancer and lost most of my hair then when it came back it came back frizzy. I've decided to start straightening it which I didn't have to do before. But I'm guessing that will damage it? I don't really want to be spraying carciongens near my face and mouth so wondered if anyone can recommend any organic heat protectants? If it was in non-spray form that would be even better although these seem hard to come by. Not sure I want to be ingesting anything that isn't food...
