I asked my hair dresser for a good product that would protect my hair from the punishment of hair dryers and curling irons that I use while styling my hair. She recommended Lanza Strait-Line Thermal Defense Heat Styler.
The product is a spray that you use right before using the heated styling appliance on your hair. It not only protects your hair from the heat, but it helps your hair maintain the style better. I have found when I curl my hair with the curling iron that the curls come much more easily and last much longer while usng this product than they do when I'm not. I find that this product is even more effective than using mousse, and without the drying effects of using mouse. This product is only available in salons that sell Lanza products.
