Diffusers

As a refresher, hair diffusers are bowl-shaped attachments that disperse the flow of air from your blow dryer, helping to dry your curls more evenly and gently while preventing frizz, encouraging definition, and creating major volume. So rather than your hair blowing wildly into the wind (which = tangles/flyaways/nightmares), a diffuser cups and nestles your hair in one place while it dries.
