How to lighten hair with hydrogen peroxide correctly

Well-groomed hair of a beautiful blond color -is the dream of many women. And to make this dream come true, women first need to bleach their locks, and then, if necessary, tint them, giving them the desired light shade. To lighten hair, hydrogen peroxide has been used since ancient times, today there are many products of different brands, but their basis, as before, is hydrogen peroxide. The products are available in different concentrations. To determine the required concentration, you must first determine what color you want to get as a result, and also evaluate the structure and quality of the hair. The main indicator is their hygroscopicity, that is, the speed with which they absorb moisture. If they are very poorly wetted with water, the concentration will be much higher than if they absorb moisture quickly. To lighten thin porous hair, hydrogen peroxide is used at a concentration of 4-8%, and hard, thick hair - 8-12%. The principle of bleaching is that hair treated with peroxide is oxidized by oxygen, due to which the pigment that determines its color turns into a colorless substance. To speed up this reaction, hairdressers use ammonium bicarbonate or ammonia, which should be added in a strictly defined amount, since their excessive use will not only not improve the bleaching result, but, on the contrary, will worsen it. The solution must be prepared immediately before applying hydrogen peroxide to the hair, since the process of oxygen release begins immediately and continues for a certain time.

How to prepare a solution of hydrogen peroxide?

The amount of peroxide solution requiredhydrogen depends on the thickness and length of the hair. Usually, to lighten medium-length locks, 50-60 ml of the composition is required. But it is better to prepare the solution with a small reserve to eliminate the need to interrupt the process of applying the composition, since this can contribute to uneven lightening all over the head. The solution can be prepared in porcelain, glass, plastic or enamel dishes. Metal dishes cannot be used, since the metal will react with the peroxide and cause the decomposition of the composition. The brush for working with peroxide should have synthetic bristles, since natural ones are very quickly destroyed by the action of the composition.

How to properly lighten hair?

Before bleaching, hair should not be washed,so that the natural layer of fat that can protect them and the scalp is not removed. The roots are bleached much faster than the ends, since the oxidation reaction under the influence of heat coming from the scalp occurs faster. Therefore, in order to lighten the hair evenly, when bleaching with peroxide for the first time, you should first apply the solution to the ends, stepping back 2 cm from the scalp, and when the desired color is almost achieved, you should apply the solution again, this time starting from the roots. If your goal is to lighten the regrown roots, then you need to apply the solution only to the roots, without touching, if possible, previously bleached hair. To facilitate the coloring process, you should use a thick composition. If you want to lighten individual strands at home, to do the so-called highlighting, you can use a special rubber cap or a regular bathing cap that fits tightly around your head, making small holes in it. In this case, you can bleach your hair with high-concentration hydrogen peroxide, since there is no risk of burning your scalp. In addition to the cap, to bleach individual strands with peroxide, you will need a hook (not metal), which will be used to get the strands onto the surface of the cap for subsequent bleaching. When bleaching, remember that you should try to do as little harm to your skin and hair as possible. To bleach natural light hair, you should use a low-concentration composition, and in addition, when bleaching any hair, carefully monitor the process.
