After air-drying, my hair gets these little waves in it. With my current hairdryer, I still have go back in with a straightener to get all the waves out that my hairdryer didn't get the first time. With this InfinitiPRO hairdryer, it eliminated that last step! The attachment that comes with it really helped to tame the frizz as well as straighten it without frying my hair. I really try to make an effort to not use any extra heat on my hair if I don't have to. I am also in LOVE with the cool setting on this hairdryer! It gets much cooler than any hairdryer I have tried in the past. I also appreciate that it is lightweight and fits into my hand nicely. I gave this 4 stars because I wish the air pressure was a bit more intense. My hair holds on to moisture very well, so it can take me a while to blow dry it if the air pressure isn't high enough.   **This review was collected as part of a promotion.
