I’m so Inlove with this hairdryer!! I had no clue shark even came out with one! My first time trying it wasn’t until the day after I got it and I used it on my moms head after she got out the shower, because we both equally have really curly hair, we used the anti frizz one and let me tell u THE BEST, her hair was 100% straight and not frizzy! I’ve never had a dryer straighten hair!!! I love love LOVE this product!
