What’s the story behind Keratin Complex®?

It begins with keratin protein, the proven ingredient that helps make hair smooth, manageable and youthful-looking. From our signature Smoothing Therapy—the award-winning keratin hair treatment that started it all—to the launch of a full collection of keratin-enhanced professional hair color, Keratin Complex is redefining what it means to be an industry leader.

How it works.

Keratin is a fibrous protein found naturally in the hair. It acts as a protective shield against humidity, the primary cause of frizz. Over time, the hair loses keratin from exposure to the sun, the environment, styling and chemical services.

• Prevent humidity, the main cause of frizz, from impacting the hair.

• Achieve a flawless blowout at home: Your hair is more manageable, blow-drying becomes quicker and easier, and daily styling time is significantly reduced.
