The Science

What is keratin?

Keratin is a protein and the major component in skin, hair and nails; in fact, the hair is mainly comprised of keratin-associated proteins. Keratin acts both as an external protective protein in the cuticle (the outer layers of a hair strand) and as an internal structural protein in the cortex (the inner core of the hair that helps determine its strength).

Keratin is depleted when hair is damaged physically, chemically and/or from environmental factors, such as the sun. This keratin loss exposes the hair’s cortex, making it susceptible to additional damage, and causes porous spots to develop—much like potholes in a road. Replenishing lost keratin helps to correct porosity and smooth the hair’s surface. It restores strength and elasticity, giving the hair a more youthful, healthy appearance.

What is unique about Keratin Complex Smoothing Therapy?

The innovative technology in our Smoothing Therapy treatments binds keratin to the hair. This process helps prevent humidity from penetrating the hair, thus locking out frizz. In addition, Keratin Complex Color Therapy incorporates this signature keratin technology into the hair-coloring process, which helps to make the hair stronger and smoother as it undergoes a color transformation.
