In recent years, non-oxidative hair color products have become more popular. These hair dyes have larger pigments that settle on the hair and wash out more quickly. Some manufacturers now offer permanent oxidative hair colors that do not contain ammonia.
These types of colors are still very effective, though. Ammonia is a powerful alkaline, and the most common chemical reaction it causes is the opening of the cuticle. Some newer color formulations have less ammonia, such as Schwarzkopf Professional tbh.
What should I consider before choosing a color?
When you choose a color for your hair, consider the oxidation process. All non-oxidative products use an oxidation catalyst to create a permanent color.
This process is called a “processing step.” A hair dye is made by mixing color and developer in a specific ratio. This step is essential to ensure that the hair color is as effective as possible and that no side effects occur.
What is in oxidative hair dye?
An oxidative hair dye contains an oxidizer like hydrogen peroxide and a dye intermediate, such as paraphenylenediamine—the oxidation reaction results in a colored reaction product.
A non-oxidative hair dye does not use hydrogen peroxide and instead contains preformed dyes applied to the hair using a plastic applicator brush.
A deamination reaction does not happen if the dye contains an oxidizing agent. In non-oxidative hair color, the amine group in the molecule is removed, and the amine group is added.
When the hydrogen peroxide and dye solution are mixed, a chemical change in the hair. It is important to note that a color change in the hair follicle can only occur after a specific time, so checking whether the color is safe is vital.
What is non-oxidative hair color?
Non-oxidative hair color does not need an oxidizing agent. It will not cause hypersensitivity in the hair fiber, which will prevent it from fading quickly. Another type is acidic.
These types are non-oxidative. An oxidative color is the opposite of a natural one. The oxidative reaction will be a stronger one than a non-oxidative color.
Are all hair dyes being oxidative?
All hair dyes are oxidative. All of them contain hydrogen peroxide. Both types are permanent and demi-permanent. In addition, all non-oxidative hair colors are non-oxidative.
The difference between a temporary and permanent coloring is the amount of hydrogen peroxide required to undergo the reaction. In contrast, a quick color is one that only requires a little oxidative action.
Both types of hair dyes are non-oxidative and contain hydrogen peroxide. A non-oxidative color is colorless. A dye that uses hydrogen peroxide does not have a catalyst.
However, an oxy-peroxide product requires a developer to achieve a vibrant color. An oxy-peroxide product is a chemical solution used to activate a chroma color.
Is there any hydrogen peroxide is present in non-oxidative hair dyes?
As mentioned, non-oxidative hair dyes do not contain any hydrogen peroxide. They are not permanent and require an oxidative hair dye to be used. This type of hair dye is used in temporary applications.
Because it requires a developer, it is colorless. But if the color contains hydrogen peroxide, it will produce an ionized solution. The pigments in oxidative products can be more stable than demi-permanent ones.
Which dyes are used for semi-permanent hair coloring?
The dyes used for semi-permanent hair coloring are non-oxidative. This type of hair color is based on plant-based ingredients. These plant-based colors are mixed with hot water to make a paste. They are applied to the hair and leave it on for 30 to 45 minutes. Some of them may contain other ingredients to change their tonal qualities. They are not oxidative, but they contain synthetic pigments that have a chemical reaction with the natural dyes in the scalp.
