The InfinitoPro by Conair is a very powerful hairdryer with 1875 watts.  It is lightweight and dries my hair fast.  It is great for damaged hair as it is frizz free and it gently dries your hair to keep it from being damaged.  The InfinitPro also comes with extra attachments which include a diffuser if your hair is curly or wavey and a concentrator for a smoother style.  Using this hairdryer I am able to get the volume in my hair that I really like.  I am very happy with this hairdryer.
