My bangs are fried. Please help :(?

I straighten my hair everyday, I always make sure to use a heat protectant before (Tresemme Heat Tamer Spray). I know it's unhealthy, but I also wash my hair everyday as it gets greasy easily. Recently, I've noticed that my bangs are extremely fried. I have side bangs that cover my right eyebrow. They are also breaking off from straightening them so much. The straightening iron I use goes up to 430 degrees. I really don't want to cut the damaged part of my bangs off, because if I did they would only be about an inch long! Is there any products I can use that will help my bangs? :(
