Keratin Complex Smoothing Therapy treatments are professional smoothing treatments powered by our signature keratin. All treatments are performed in-salon by a professional stylist. Smoothing Therapy treatments repair damage and breakage, reduce frizz, curl and unruly flyaways, and make the hair smoother and healthier-looking. They also prevent humidity, the main cause of frizz, from impacting the hair. After a Smoothing Therapy treatment, it’s easier to achieve a flawless blowout at home: The hair is more manageable, blow-drying becomes quicker and easier, and daily styling time is significantly reduced.
