Query: NOT for Fine Hair - Tourmaline Revlon RV544

After using this tourmaline dryer the first time, I thought I had forgotten to rinse out my conditioner.The second and third time using the dryer, I suspected my flat lifeless hair was due to the tourmaline dryer (which it was).There were other reviews saying this dryer is not for fine hair, and I should have listened. When I realized it was the tourmaline-type dryer making my hair flat and lifeless, I went to the store and bought a NON-tourmaline dryer and now my hair has its volume and bounce back.
