Keen Paint
Keen hair dye with its inimitable palette was created by Ewald. The company began its history in 1940 in Germany. Its founder is a German hairdresser from the city of Frauenwald named Robert Schmidt.
Initially, he produced eau de toilette for hair, which included mountain herbs. For several years, the company was engaged in the development and production of eau de toilette, an elixir for hair based on birch sap and cologne. However, a real breakthrough was a drug for a perm. 
The organization is a family business led by the founder’s descendant Robert Ewald, who runs the production process. In 2009, Ewald begins production of a creative professional line, which becomes the pinnacle of the development of the company – TM KEEN. Translated from English keen means striving, passionately wanting something.
Keen hair dye, the palette of which has more than 60 shades, was launched on the market after the care products and styling of the same line.

Composition and active substances
Keen hair dyes are a high-quality creation, the palette of shades of it was created by a team of German experts using cutting-edge technologies that provide complete hair care.
The composition of paints includes unique components:
-
Keratins are fibrillar proteins that have the mechanical ability to resist destruction. Keratins are constituents of the epidermis of the skin. They are part of the natural composition of nails and hair.
- Milk protein is an inorganic crystalline substance that accelerates the course of biochemical interactions and is of significant importance in the process of metabolism.
- Panthenol is a substance whose main component is a group of vitamins that are of great importance in cellular metabolism. This substance is used to moisturize and treat various skin defects in pharmaceutical and cosmetic products.
- Hydrolyzed silk is a natural substance that, during the chemical reaction of interactivity with water, collapses and forms new, easily digestible elements.
Additional components are: minerals, vitamins, aromatic oils.
Staining safety
Keen paint has been designed for high-quality dyeing. Thanks to unique developments, it works in a gentle mode for curls and scalp, at the same time gives them a radiance and a steady tone. One of the components of the dye is ammonia. This substance is an alkali. It is necessary in order to open the outer layer (cuticle) and penetrate the color dye into the hair.
Ammonia is known to irritate the skin, even to an allergic reaction. In this regard, international standards have been developed, according to them the amount of alkali in the paint should not exceed 6%. All Keen dyes contain no more than 3% oxidizing agent. Due to this, coloring is absolutely safe for skin and hair and does not cause allergies.
Ewald also developed the soft tinting series of the Keen line. It is designed for thin brittle hair. Its peculiarity in the oxidizing agent is its ammonia content is only 1.9%, and the coloring matter is cream oil.
How long does the color last
Any Keen dye has a soft coloring, practically without damaging the hair. A specially selected complex, which includes amino acids and olive oil, cares for emaciated hair.
Hair acquires shine and a healthy look for a long period. Shades of a certain series do an excellent job with painting gray hair. Even if the gray hair is focal, the dye will not leave any transitions – the color will be evenly distributed over all hair.
The components of the cream paint fill the cuticle with the coloring pigment and close it. Due to this, the color looks saturated and remains for a long time inside each hair.
The olive oil and macadamia nut included in the preparation envelop the hair along the entire length, thereby preventing leaching and burnout.
