Testing the evaluation of the hair STRENGTHENING and REPAIRING ACTION

In conjuction with the Department of Drug Science and Technology, Univeristy of Turin.

In vitro test made on:

  • natural hair strand
  • permed hair strand
  • hair strand bleached once
  • hair strand bleached twice

The REPAIRING ACTION has been evaluated using a scanning electron microscope to evaluate the morphology/structure of the hair before and after using the product.

The REINFORCING ACTION has been evaluated by means of a tensometer via a verification of tensile strength of the hair before and after using the product.

From the results it can be concluded that:

REPAIRING ACTION: the setting phial helps to restore capillary structure; cuticle morphology appears to be much more regular after treatment, above all after repeated treatments and especially for hair that was significantly damaged before treatment.

REINFORCING ACTION: the setting phial allows to increase the tensile strength of the hair after just one treatment (for example permed hair by almost 30%).


PERMED HAIR:

Permed hair that has undergone neither shampooing nor treatment.

Permed hair after four treatments with KH Setting Phial.

HAIR BLEACHED TWICE:

Hair bleached twice that has undergone neither shampooing nor treatment.

Hair bleached twice after four treatments with KH Setting Phial.

The experiments have generally shown that the EFFECTIVENESS of the setting phial increases with an increasing number of application, both in natural hair and hair that had been previously subjected to drastic physico-chemical procedures that alter hair structure, such as perming and bleaching.
