I used to live by my diffuser when I was younger, spending precious time crunching each curl. Recently, though, I’ve been air-drying due to a lack of time and diffusing on special occasions. You can imagine my shock when a hairstylist told me months ago that diffusing can create frizz because it’s concentrated heat that can lead to fluffed up curls. So, at a recent event, I met Mr. John Frieda, of Frizz-Ease fame, and we had a conversation about diffusers.
