I know it may sound crazy, but is it possible to do a home keratin treatment with JUST a blow dryer? I wouldn't expect it to work just the same as using a 400 degree iron on your hair, but would there be some benefit/change? I'm not looking to straighten it, just blast some of the frizz and make it easier for me to care for it.

I have a fear of using heat on my hair so that's why I ask about using only a blow dryer.
