I've noticed that the ends of my hair are smelling burnt. I'm pretty sure that my hair smells this way due to me straightening my hair almost every day, and possibly because of how much I cook without pulling my hair up. Is there any way to revive dead ends without cutting them off? I have been trying different shampoos and conditioners that are supposed to help "revive" dead ends, but it's starting to take a toll on my scalp, like being too dry.
