There are many ways in which you can adjust the shade of the hair. You can lighten, tint, get rid of gray hair, tint the roots, radically change or just update the color of the strands.
Color classification
In the modern world, hair dyes are widespread. Almost every woman at least once in her life changed the color of the strands. With the help of such funds, you can change the natural shade or tint gray or bleached hair.
Dyes are divided according to the type of exposure to the hair sheet:
- permanent dyes (containing ammonia),
- semi-permanent (sparing),
- direct action (without ammonia),
- clarifying (contain hydrogen peroxide and ammonia),
- tinting (shampoos, balms, tonics),
- vegetable (henna, basma and so on).
If you want to radically change the color, it is recommended to use a permanent dye. This is the most resistant hair dye. It will allow you to color the strands 2 or more shades darker or lighter than the natural base.
Permanent paint
Permanent hair dye is a permanent coloring agent. The chemical composition penetrates deeply into the hair structure and paints gray hair 100%. This is because an oxidizing agent (such as hydrogen peroxide) and ammonia are mixed with the dye before use. The formulation of permanent dyes is very complex. Manufacturers go to great lengths to achieve lasting color. Therefore, a negative effect on the hair, for example, its brittleness or loss of elasticity, if properly followed, is minimal.
The reactions that are formed in permanent hair dye, in many cases, are carried out due to the content in the formulation of ammonia. This chemical compound makes the hair flakes rise, which allows the molecules of the paint to penetrate the structure of the strands. Thus, staining occurs.
It is worth noting that permanent paint can not be painted as often as direct-acting dyes or tinting agents. The chemical formula used in the composition makes changes to the structure of the hair and damages it. Due to the stronger effect, the resulting color of the strands is not completely washed out. Permanent dye is the most resistant hair dye. As the strands grow back, you will have to color the root zone and renew the hair sheet no more than once every 30-60 days.
Composition
Permanent hair dye contains many chemicals. The most important of these are ammonia and hydrogen peroxide. Ammonia is used directly to change the color of the strands. In some cases, it can cause itching, irritation and burning when applying the coloring composition to the hair and scalp. Hydrogen peroxide (or an oxidizing agent) when mixed with ammonia allows the color to penetrate deep into the bulbs of the strands. Usually in sets of permanent hair dyes is a 6 percent oxidizing agent. It is stored separately from the paint itself and ammonia, and is mixed immediately before the procedure. The higher the concentration of hydrogen peroxide in the dye, the more severe the damage is caused by the staining process.
Operating principle
In order for permanent hair dye to change hair color, a combination of chemicals such as ammonia and hydrogen peroxide is used. Hydrogen peroxide bleaches the natural shade of the hair. In the process, oxygen is released, which allows you to start a chemical reaction. After this, ammonia destroys the outer cuticle around the hair, allowing chemicals to enter inside.
Unfortunately, some ingredients can be potentially harmful to your curls. The chemical reaction, in addition to the harmful effects on the hair, can also irritate the skin, eyes and respiratory system.
Mode of application
In order to prepare a coloring composition, it is necessary to mix all the ingredients. If you purchased a ready-made set of permanent hair dye, follow the instructions. In the case when you bought everything separately, it is necessary to mix the dye and oxidizing agent in a specially prepared container. Then you can start the staining process. Remember to wear gloves and a cape to protect your clothing. It is also preliminarily recommended to apply oily (baby) cream on the hair growth zone to protect the skin from the effects of paint.
Next, the mixture is first applied to the roots of the occipital area, then the front. After that, you need to dye your hair along the entire length. Upon completion of the application of the coloring composition, it is necessary to withstand some time. Usually this interval should not be more than 50 minutes. After that, wash your hair with water and shampoo. The exact steps should be described in the instructions for the paint.
Brands
Permanent hair dyes are of two types: professional and ordinary. The former are sold in specialized stores, and the latter in stores. Professional paints differ in the appearance of the package. It is usually plain, with no frills. Also, usually when buying such funds, an oxidizing agent, gloves are purchased separately.
Conventional permanent dyes have bright packaging, the kit includes a ready-made kit, necessary for a single hair dyeing.
The modern market is filled with an abundance of permanent paint brands. The most common ones are:
- Matrix
- Igora Royal.
- EstelProfessional.
- Kapous.
- Londa.
- Garnier.
- Wella.
Each of the brands provided has its own line of hair colors: with ashen color, dark, bright shades, for blondes or for tinting gray hair.
Shade selection
The color palette of permanent dyes is very extensive. Each manufacturer is usually provided with several lines of such funds. First you need to decide what your base of natural hair is, what color you want to dye the strands in. Based on these data, dye is selected. For example, to determine the color of natural hair, you must apply the shades proposed in the palette.
The most suitable color has a specific number. Based on this figure, a dye is selected. If you determine that your tone is at level 8, then the paint must be taken in the 8th row. The next 2 digits are responsible for the desired shade and nuance. For example, consider hair dye with an ashen color EstelPRINCESS ESSEX 9/16 blond ash - purple. The number 9 is the level of the depth of tone (blond), 1 is the primary color (ashen), and 6 is the additional nuance (purple). The last number is usually responsible for the correction of unwanted shades. In this case, purple neutralizes unwanted yellowness, which often appears when lightening hair.
Understand all the nuances of color in 5 minutes, of course, will not succeed. For this, professional hairdressers undergo special training. Therefore, it is better to entrust the master with determining the tone of the natural base of the hair and the selection of dye.
