Keratin during daily use

It sounds loud enough, therefore, it is more correct to say what the advantages and disadvantages are during the daily care of hair that has been saturated with keratin.

Many girls say that the first few days after the procedure is quite difficult to do without rubber bands and pins. Also, you can not clean the hair behind the ears to get the maximum effect from the procedure.

Not very convenient is the fact that in the first days after the procedure it is impossible to wet the hair. But this is not always possible, especially if the humidity on the street is high enough or it suddenly started to rain. Perhaps you were invited to a picnic and sprinkled with water even when you asked not to. In other words, there are certain situations that cannot be avoided.

The disadvantage of many of the fair sex is noted at the moment when the self-leveling of the curls, which were real keratin, occurs.

So what to do?

In other words, choose such a procedure or not. - every girl will decide for herself, because a lot depends on what prerequisites for keratin straightening are, and whether there is a need for it at all. If there are light waves on the hair, and imperceptible strong irregularities, it makes sense to do lamination, and to stop straightening using keratin.

Technique of keratin straightening

The procedure for hair restoration is long, so count the time before going to the hairdresser. Actions are performed in compliance with a certain sequence, we consider it in order.

First, the master prepares the hair for further manipulation. He is combing strand by strand with a wooden comb, excluding possible knots and confusion.
After preparation, the head must be washed with shampoo, which includes keratin. Such a move will make the strands smooth. When an expert washes his hair, he massages the curls with his hands, revealing scales. This will provide further deep penetration of keratin inside.
After washing, it is necessary to dry the hair, collecting excess moisture with a towel. Then the strands are combed, an inspection is carried out for the absence of nodules and tangled particles. Then you need to wait another 5-10 minutes so that some of the moisture will evaporate from the pile.
After the strands dry out naturally, they are covered with a keratin-based straightener. This part of the procedure takes about 30 minutes, it all depends on the professionalism of the master.
After distribution and thoroughly moisturizing each of the hairs, keratin must be sealed. The master conducts a partial drying with a hairdryer, then heats the iron to straighten up to 220 degrees. Such a course closes the scales, and under the action of heat nutrients enter the body.
After thermal treatment, the hair is washed again to remove residual keratin. Then the mop is dried with a hairdryer, so that the strands look smooth and shiny. When keratinizing, the girl no longer needs to straighten her hair with an iron; they will remain so for a long time.
Despite the many hours of work, the result will pleasantly surprise you. Hair will remain shiny and healthy for about six months. After this period, the keratin will gradually begin to leach out of the structure, so it is possible to repeat it.
To determine when another session is required, it’s enough to pay attention to the roots. They will "stand out" from the general appearance of hair, looking dull and a little disheveled. You can get rid of regrown roots by asking the master to process only this part. The procedure does not require a lot of effort and money.

Result keratin hair straightening

You should not expect a negative result from such a procedure, especially if you entrusted your hair to a true professional. So, what to expect after the keratin straightening? Let's look at these aspects in general.

Perfect structure. Under the influence of heat keratin penetrates deep into the core of the hair. As a result, the hair is homogeneous to the touch, the hairs do not tangle, they do not stick together in nodules. You easily pass along the strand with your hand, it will not get stuck between your fingers. The same effect is observed when combing with a comb with nearby teeth. Improving the structure affects the health of all hair.
Smoothness. As can be understood from the name of the procedure, the hair is straightened using keratin. This is the effect that girls with curly or protruding hair want to achieve. Straightening keratin will allow you to get such a result for a relatively low cost and a small amount of time. Even under the action of moisture or when in the rain, the hair will no longer curl, remaining perfectly flat and smooth.
General recovery. Not everyone knows that human hair for the most part consists of keratin. The addition of additional nutrients to its structure cannot be reflected negatively. A heap heals on what is called, on all fronts. Hair stops to split, fall out, break. The color looks saturated, lost porosity and curls. Many girls notice that after the procedure, a “fluff” of new hair appears on the head. This is made possible by the activation of dormant bulbs.

Pros and cons of keratin straightening

Before the procedure is worth it all carefully consider, consider the positive and negative sides.

The composition of the means and principle of action

Keratin straightening helps not only to smooth the curls, but also to heal them, add shine and elasticity. The procedure is performed with a special tool, due to which the structure of the hair shaft is restored, cracks and damage are filled with this composition. A protective film appears on the hair, due to which straightening occurs, and also curls are protected from negative external influence.

The harm and benefits of such a procedure are determined by the composition of the agent that is used. It is 90% made up of keratin - the fundamental component of the hair. He is Brazilian and American. In the first case, there is a long lasting effect and reliable thermal protection. However, along with herbal ingredients, Brazilian keratin contains the preservative formaldehyde. When using irons, it evaporates and settles in the lungs. The American version instead contains methylene glycol, as well as active biological additives. At the same time, the aesthetic state of the curls is significantly improved, but the cost of the product is much higher.

Like every cosmetic procedure, Keratin straightening has its advantages and disadvantages. This procedure allows you to achieve the desired structure of the hair and ease of care for them. Despite all the drawbacks, keratinization remains popular among women.

What is keratin?

Keratin is a protein of special structure and strength that makes up the stratum corneum of hair, along with other components. Keratin itself is in a certain sense “liquid hair”. This explains its protective properties.

The main part of the procedure of keratin hair straightening takes place under the influence of high temperature, as a result keratin is rolled up and envelops the hair with a protective film. The film is short-lived and gradually washed off the hair under the influence of shampoos.

To whom this procedure is recommended and when to do it.

Cosmetologists advise that keratin hair restoration will be carried out correctly in the following cases:

when it is necessary to achieve smooth strands for wavy or curly hair and give them shine,
to facilitate combing and styling naughty and furry hair,
for dull, weak and lifeless strands keratin is a real salvation, it will not only give a healthy shine to your hair, but also strengthen it,
in the presence of split ends, as well as when the hair begins to break.

The advantages of keratin hair straightening

Cosmetologists present several advantages of this procedure. To decide whether to make a keratin hair straightening or not, everyone will be able to appreciate all the positive effects.

The main advantages of the procedure include:

Easy combing. Those who daily have to comb curly hair, do not need to explain how much time, patience and nerves are spent on this procedure. Having made keratin hair straightening, they can be easily combed even wet.
The universality of the procedure for all types of hair. For example, fluffy and thick strands will gain gloss, but will not lose their attractive volume.
Such straightening is a kind of strand treatment. Interacting with the hair molecules, the keratin mixture gradually grows together with them.
Hair becomes shiny and smooth. And this is evidence of well-being and health. This advantage is one of the main among all.
The duration of the effect and a simple correction. After the procedure, keratin hair straightening the result is held for 1-2 months. And with each subsequent procedure, keratin accumulates in the hair, which after about a half to two years of constant use can increase this period of keratin preservation up to 6 months.
Preservation of styling. In any weather on the street - rain, heat, wind - laying will remain in its original form. Hair will not start to be confused and curled.
Protective function from an aggressive environment. The procedure perfectly protects hair from dust, polluted air, poor-quality tap water, and negative exposure to sunlight.
Antistatic action. Hair stops electrifying and pushing, the tips do not split. This advantage is especially important in the cold season.
Thanks to keratin recovery, it is possible to fix the hair after an unsuccessful perm. If the result of "chemistry" you did not like, then keratin is the only way to return straight hair after 2 weeks.
Creating the effect of always well-groomed styling without daily spending of time and cosmetics. Even disobedient by nature strands after using the keratin composition become malleable and easily fit.
Keratin does not make heavy and does not stretch the curls, and the procedure itself increases the elasticity and strength of the hair.
Thanks to keratinizing, hair is much easier to tolerate perm and exposure to high temperature devices (hair dryer, curling iron, iron, heated hair rollers, etc.).
After washing the dirty head, the hair becomes smooth again.
Keratin introduced into the hair structure allows them to breathe, due to this they keep volume for a longer time and keep their shape, they are not so quickly polluted. In addition, keratin in liquid form does not burden the hair, and the hairstyle retains its naturalness.
Keratization procedure is permissible simultaneously with staining, coloring or highlighting, it greatly facilitates both the work of a cosmetologist and reduces the time spent for the client.
Keratin straightening allows you to adjust the styling locally. When after some time the roots grow back or the tips start to curl, the master will be able to treat only these zones with keratin.

Disadvantages of keratin hair straightening

Disadvantages of keratin hair straightening are also available and must be taken into account when deciding on the procedure. In some cases, you can get a completely unexpected result.

This harmful substance makes the application process not very pleasant, usually the wizard and the client’s eyes get from the pungent smell.

The main significant disadvantage of the procedure lies in the fact that most of the compositions for keratin straightening contain formaldehyde.

Therefore, the procedure should be carried out in a room with good ventilation in order to avoid formaldehyde vapor poisoning. However, if you do not spare the money, you can find the means to straighten hair without this unpleasant component. The risk of poisoning with formaldehyde can manifest itself only if the procedure is performed by an inexperienced cosmetologist in an unventilated room without complying with all safety rules.

In addition, the disadvantages of keratin hair straightening include:

Reducing hair volume. By eliminating the effect of fluffiness, hair loses a little in volume. Therefore, this procedure is not recommended for girls with sparse hair.
Within 2 weeks after straightening, it is not possible to dye the hair with ammonia. During this period only tonics are permissible. A non-ammonia paints can be used after 20 days after the procedure.
Allergic reactions are possible. If the girl has intolerance to any of the components of the tool - the procedure must be abandoned.
The result of keratin hair straightening depends largely on their initial state and health, as well as on the professionalism of the master and the quality of the tools he uses.
After the procedure, you will not restore that wave of hair by nature. Only in 1-2 months the hair will return natural waves.
A truly high-quality procedure is quite expensive.
Some girls report deterioration in the condition of their hair: more often it is necessary to freshen the ends of the hair with a haircut, sometimes the hair with a look becomes greasy, they have to be washed more often than before keratin straightening.

Non-critical procedure flaws

These disadvantages of the procedure can rather be called inconveniences, or rather, the very sacrifice that girls have to give for beauty:

There are cosmetic compositions, after the application of which girls can not wash their heads for 72 hours and visit places with high humidity - saunas, baths, swimming pools, the sea coast. Hot humid air, salt and chlorinated water destroy keratin. Therefore, girls who practice daily shampooing need to be patient and free from work. And do not forget the umbrella, so that after the procedure on the way out of the cabin nature does not spoil the result. If immediately after keratin straightening you fall under a shower, the entire effect from the hair will simply disappear.
You can not perform any aggressive mechanical actions with the hair during the same time (3 days), for example, to collect them in a bundle, tail, weave braids, gum, and hairpins. For the first time, it is generally desirable to leave hair loose. However, if modern, expensive keratins were used during the procedure, this period is reduced to one day.
The procedure lasts a long time. And if the length of your hair is below shoulder level, be prepared to spend at least 3 hours on straightening. For long-haired girls, the whole process of straightening can take up to 5 hours. In any case, a trip to the salon for this procedure must be allocated in advance no less than half a day.
On thick curls, keratinization will have a short-lived effect.
