The chemical method of straightening
The chemical method gives results for up to 3-4 months,sometimes less, naturally it depends on the quality of the method and the structure, as in all other methods. This method is similar to a perm, familiar to many, only with the opposite result. The necessary substances are applied to the hair, then these substances are fixed with a special composition and treated with conditioner. For this, ammonium thioglycolate and sodium hydroxide are used. Sodium hydroxide is a very aggressive substance from a series of alkaline ones, deeply penetrating into the hair, changing its structure, softening and increasing its volume. After this procedure, the hair becomes more voluminous and silky and completely straight. At first glance, everything is very good, but this method is very harmful, and after they become dry, brittle, lose elasticity, the hair shaft becomes very thin. Restorative agents will slightly improve this, not very good situation. Instead of sodium hydroxide, it is possible to use another drug - ammonium thioglycolate, it acts more gently, but the effect does not last as long.
Japanese Straightening Method
This method was developed in the early 2000s.years, but to this day it is the most effective, long-lasting and safest way to straighten curls, despite the fact that it is also chemical. If you ask the question: "How to straighten hair forever?", then the Japanese method will give a more suitable answer, because only the grown hair will need such treatment. Japanese straightening is flowing straight strands, without any damage, unlike the first described method. Moreover, with the help of the Japanese method, damaged hair is restored. The fact is that the composition for treatment includes a unique drug cystiamine, rich in proteins, which promotes both treatment and improvement of their condition. A special straightening composition penetrates not just inside the hair, but into its molecular structure of keratins and changes the bonds in it. As a result, even natural curls become completely straight. The Japanese technique has two important advantages: a noticeable improvement in both appearance and their general condition, and long-term straightening. Three types of Japanese straightening The composition of the chemical elements of the Japanese method varies depending on the type of hair: natural uncolored, damaged dry and colored - a specific composition is selected for all of these types. The procedure of this method is quite simple, but the more experienced the master who carries it out, the better the result will be. The hair is covered with a special composition for straightening, after a while it is washed off, then comes the most important stage of straightening. The master pulls out each curl, trying to straighten it completely, and this is quite a long procedure. If this is done well, the result will exceed all expectations. The straightening procedure will have to be repeated for 6-8 months only on the regrown hair. And all this time they will be perfectly straight. The Japanese method differs from the usual chemical one in that the hair is not damaged. Due to the fact that the structure is completely restored, they can be dyed and extended.
Keratin straightening
The effect of keratin straightening is from 2 to4 months, depending on the straightening composition and hair type. Healthy, shiny, smooth hair - this is the result of the method we will talk about in this section. Healthy hair is 88% keratin - a complex protein. With unbalanced or insufficient nutrition and stress, keratin molecules are damaged, destroyed, and hair loses elasticity, shine and smoothness. Hair scales no longer fit tightly to each other, hair breaks and tears. Keratin straightening is the saturation of hair with this very keratin. It fills all the empty space in the hair structure, restoring it. There are many manufacturers of keratin straightening compositions, but compositions produced in Brazil and America are in great demand. A large number of good reviews from clients who have used these compositions confirm this. The technology of hair straightening and the essence of both compositions are similar. But the main difference of the Brazilian composition is a small content of formaldehyde. And this chemical is released as steam when heated.
American composition and stages of the procedure
Composition for American straighteningis positioned as a formaldehyde-free, safe and healing product. The American composition is usually a little more expensive than the Brazilian one. The straightening technology consists of three stages:
- carrying out the cleansing of the hair from dirt, dust, surplus grease and the remains of styling products, after which the hair itself becomes more susceptible.
- application of the composition of protein and keratin (thisthe composition of the master selects by the type of hair) along the entire length, retreating from the roots by several millimeters. And along with this composition, the hair is dried with a hair dryer, non-flammable air, using a large brush.
- small strands straighten with iron, heatedup to 230 degrees. Under such a temperature effect, the protein keratin is sealed in the hair, folding, the structure is restored, previously damaged, a smooth layer appears, which gives shine.
The effect is achieved immediately, but the completionThe necessary processes in the structure last approximately 3-4 days, and during this time you should never wash or deform your hair. We are talking about hairpins, elastic bands, various clips, and even wearing a hat is not advisable.
A small addition
If you are used to constant coloringyour hair, it is better to do it before the procedure. An additional bonus will be increased durability of the color, since its pigments will be “sealed” inside the hair for a long time. After receiving the procedure, it is worth giving your hair a break for two weeks. Keratin-straightened curls require special care - keratin-enriched masks and sulfate-free shampoos. For at least four months, your hair will look perfect, delighting you with smoothness and shine. Keratin straightening is not a cheap pleasure. Its price depends on the length and ranges from 3,000 to 15,000 rubles. But this does not stop girls and women striving for healthy beauty. As noted by those who have done keratin straightening, the result is worth it. This article tells about several types of long-term straightening: one is more expensive, another is cheaper, some type is more effective, another - However, this also applies to possible hair damage. It is up to you to decide which method to choose if you need to make your hair smooth and beautiful.
