Kao develops technology to make it easier to straighten habits and swelling hair

 Kao has been engaged in research on the essence of getting healthy and beautiful hair for everyone, and has recently developed a technology that makes it easier to straighten habit and swelling hair.

Many people with habits and swelling hair are worried that "styling is not good" and "even if you think you are doing the same styling, the finish will change depending on the day". The reason is that the shape of the habit and swell hair is different for each hair, so it is possible that a slight difference due to styling will affect the finish.

Therefore, in our research, we considered changing the original hair to a property that makes it easier to style, so that even habitual and swelling hair can be made into "straight hair that is easy to grow as you wish", and it will be shaped when pulled in a dry state. Focus on the existence of easy hair and non-easy hair. It was clarified that hair that is easy to shape has the characteristic of "high stress relaxation (difficulty of returning to the original shape when the object is deformed)".

By increasing this stress relaxation, we thought that it would be possible to make hair that is difficult to grow easy to grow.

The company has developed a technology (ingredient: isostearyl glyceryl) that acts on the inside of the hair, enhances the stress relaxation of the hair when heat is applied with a curling iron, etc., and facilitates styling.

This time, it was newly discovered that when malic acid penetrates into the hair, stress relaxation of the hair is enhanced without applying heat. By treating the habit and swelling hair with a formulation containing malic acid, it was possible to change the hair into straight hair that is easy to grow without a strong blow. Malic acid acts on the inside of the hair to make it easier to shape, so it does not harden or become sticky in a bundle.
