Ceramic barrel technology in the BaByliss Professional Porcelain Ceramic Curling irons emit negative ions to smooth and relax hair while maintaining the natural oils to bring back the hair’s natural luster and shine. Gentle, far infrared heat protects hair from fizz and damage while creating smooth, soft, long-lasting curls. With 30 heat settings and a variable temperature control of up to 400 degrees F, every curl from the tightest ringlets to the biggest, bounciest curls can be yours in a matter of minutes with a BaByliss curling iron. We suggest the 3/4” barrel for creating small to medium sized ringlets and curls, or for use on short to medium hair styles.
