Yeah, that's right. Just apply some anti-frizz serum and use a round brush held under the bottom layer of your hair and repeatedly brush it in a circular motion with the blow dryer on point. It's best to put your blow dryer to low or medium when blow drying your hair, just to cause less damage! My favorite anti-frizz serum is CHI therapy, works great!
Personally, I prefer straightening hair over blow drying it. If you want your hair to be completely straight, use a straightener. But, if you want your hair to have more movement and have a more "bouncier" effect, then in that case, blow dry your hair. Although, as we all know, blow drying causes less damage than to straighten your hair. If you decide to straighten your hair, apply a heat protectant to prevent damage, like Biosilk Therapy, it's awesome!
Hope this helped! :)
