Your questions and our answers on Keratin Alpha Sleek range.

  • What is Keratin Alpha?​

    It is the primary protein that forms the very core structure of your hair, residing at the deepest level of the fiber. It is the building block that dictates each strand’s shape, strength, and elasticity.

  • Why does Keratin Alpha determine hair outer shape?​

    Alpha-keratin is the fundamental structural protein that forms the hair. Its internal helical arrangement, along with the extensive network of bonds within the hair's cortex, dictates the strand's overall geometry, and ultimately determines if hair appears straight, wavy, or curly.​

  • What hair needs does this range address?​

    Keratin Alpha Sleek range has been formulated with stylists for all those who want to reduce frizz, improve smoothness, and keep hair straighter and softer, with results that last. In fact, while other at-home smoothing treatments only act on the surface of the hair for temporary result, Keratin Alpha Sleek transforms hair at Keratin Alpha level, for 2 weeks of smooth, frizz & volume control, ensuring daily styling in half the time. It is suitable for all hair types. ​

  • Does Keratin Alpha Sleek range contain keratin?

    Keratin is an animal-derived ingredient, also found in human hair. These products don’t contain keratin, but reprogram hair from deep inside the fiber at Keratin Alpha level, reshaping Keratin Alpha chains for 2 weeks of smooth, frizz-controlled hair*.
