I choose my barrel size depending on the look I want—the 1.2-inch barrel gives me tighter curls, while the 1.6-inch barrel creates looser waves. When I want a sleek, straight blowout, I swap in the firm smoothing brush and press it against sections of my damp hair to smooth out frizz. And when I want to enhance my natural curls instead of styling over them, I scrunch in a bit of styling cream and use my diffuser attachment to speed up drying while keeping definition.
