How long should hair dye be kept?

Hair coloring is a very popular procedure. Many women spend it on their own. Often it seems that this is a very simple process: it is enough to apply paint, hold the set amount of time, wash off - and a new hairstyle is ready.

Of course, staining alone is not particularly difficult, it requires only thoroughness, accuracy and attentiveness. Why, then, does the result not always meet expectations?

The consequences that a wrong procedure can lead to sometimes completely unexpected:

• the color is not as expected and is far from that presented on the package;
• the shade turned out unpleasant;
• color does not fit the owner;
• the strands became dull and naughty;
• hair splits, breaks, falls out.

And this is just a small list of possible problems. In many ways, they appear because, when they are going to dye their hair, few people imagine what a complex chemical reaction is, the successful result of which depends on many factors.

The time during which the procedure is carried out (it is called exposure) is one of such factors.

Experts divide dyes into four groups. They differ in their effect on the hair and, therefore, in exposure time.

They do not harm the hair, on the contrary, they bring tangible benefits: they strengthen the roots, improve the structure, and positively affect the condition of the scalp. These are henna, basma, cinnamon, chamomile, lemon, strong tea and coffee.

When staining with them, it is not necessary to observe a clear time frame.

• On packages with basma, the manufacturer indicates the exposure time (it depends on the desired result, the country from which the product was brought).
• On the basis of henna, cinnamon, chamomile, you can even make long-term nourishing hair masks (up to three hours). The duration of the procedure depends on the natural color, hair structure and the desired result. In order to get a beautiful shade, blondes need only 15 minutes, owners of light brown strands will need about half an hour, brown-haired women and brunettes - from an hour. The longer the exposure time, the more saturated the color will be.
• Lemon, tea, coffee are often used for shade rinses.

The purpose of their use is to give hair a certain shade or experimentation. They are completely washed off very quickly - just wash your hair 1-3 times.

Inside the hair, they do not penetrate, therefore, do not violate its structure. The coloring pigment is distributed over the surface of the hair, gluing the scales. As a result, the strands turn out to be smooth, shiny and obedient, but changing the natural color is possible only by two or three shades (for blondes a little more), they will not be able to radically change the color with their help.

You will have to tint your hair once every two to three weeks, since these dyes are washed off quickly enough, it will not be possible to thoroughly color the gray hair with their help. But a significant advantage is that there is practically no harm from them. Of course, it is impossible to completely eliminate the harmful effects, but it is minimal.

And finally, permanent permanent paints. They contain ammonia, hydrogen peroxide, and other chemicals. They allow you to radically change color, reliably paint over gray hair, and hold it on your hair for a long time. But at the same time they negatively affect hair structure, since they destroy the natural pigment and allow dyes to penetrate deep inside, forever changing the original color.

The exposure time is not more than twenty-five, at least thirty minutes. You don’t need to keep the dye on your hair longer, the color will not intensify from this, but it is quite possible to damage, dry out the strands. Exposure too long can even lead to hair loss.

Natural blondes should slightly reduce the staining time from the indicated by 3-5-10 minutes. Blond hair is thinner, easier to pigment. The same applies to loose, brittle, dry, damaged hair. For them, preliminary for 2-3 weeks, it is necessary to conduct restorative treatment and cut off split ends.

A few minutes before the end of the procedure emulsification recommended - moisten the hair with water, beat the product on the hair and leave for a while. This simple manipulation activates chemical processes and distributes paint more evenly.

It is no coincidence that the manufacturers indicate in the instructions the exact time and sequence of actions for two processes: when it is necessary to dye the entire mass of hair and when coloring only the roots. The last method is recommended to be used if the roots have grown, and on the remaining hair the color has faded and washed off.

In this case, the paint is applied only to the roots and is kept for 15-20 minutes, then distributed over the entire length of the strands and left for another 10-15 minutes. It is not worth neglecting this rule, since in order to refresh the color, this time is enough, and the additional chemical effect will not bring any benefit to the hair.

After staining, it is not recommended to rinse the stains with hot water. It will cause additional harm, enhancing the chemical reaction.

As a rule, a color fixer is also included with cream paint. It contains caring oils and other hair-friendly substances. They must be used. It also needs to be held on the hair for a sufficient time (about five minutes).

Next, care for colored hair should be done with special shampoos and conditioners for colored hair, since they contain substances that support pigmentation.

The health of the hair depends on both the general state of health and the manipulations carried out with them. Frequent dyeing, perm, heat treatment often lead to consequences that are difficult and sometimes impossible to eliminate. Therefore, the rules specified in the instructions are not a whim of the manufacturer, but a safety requirement.
