 NIKA Hair Beauty Excellence®


The intensive treatment K-19 is a hair reconstructor which considerably reduces hair breakage, improves the shine of your hair and gives a more natural appearance to your color. It is ideal for use in a hair salon.

The secret of the range lies in its technology at Keroxyne Complex, the alloy of 2 keratins: pure keratin which creates keratin chains inside the hair for a resistant hair fiber (it is also the closest keratin present in human hair) and oxidized keratin which creates disulfide bridges between the keratin chains of the hair for healthy, voluminous and thick hair.

This intensive professional treatment is specially formulated for damaged hair. It restores truly damaged hair from the inside out to make it stronger, more supple and more sparkling.

Ask a Question
  • I am concerned that too much keratin will result in dry or breaking hair , what do you recommend to work in conjunction with this product? And how frequently should this product be used on a head?

    The purpose of charatina is to naturally rebuild the structure of the hair, so using this product will lead to thicker and stronger hair. The decision of how many treatments to carry out depends on the current structure of your hair, usually only one treatment is enough to obtain excellent results, but for particularly damaged hair you can reach 3 or 6 treatments with an interval from one treatment to another 1 or 2 months.

    To guarantee the result, we recommend following all the steps and using the specific products of the K-Perfection range.

    To maintain the result, use shampoo and mask, once the hair is rebuilt it will be even harder and therefore the next step will be to hydrate with NIKA Age Restore.

    The result will be healthy, strong and shiny hair.
