You really have to comb the section multiple times before you get somewhat better look. Definitely doesn't make your hair perfect staright. But looks like blow dried hair but again need to spend a lot of time
This just works as a blow dryer while you're combing. if you have curly hair then it won't really help however straightened hair can be easily maintained. Basically it doesn't substitute a hair straightening iron. Good quality product overall.
Air styler is a better term than Air Straightner. It doesn't straighten much, specifically those have curly hair. Might be more effective on those hair naturally straight or inclined to straightness. But it is nice specially if u wanna have a smooth manageable hair texture. It's basically a dryer!
The one product I will suggest anyone to buy is this Philips Air Styler. It worth the money and I have even recommended to others to try the product. In our house, we have 3 of them and all of them are in perfect condition with not a single complaint.
