As you know, many women seek diversity in hairstyles. Straight hair frizz, and lush curls, on the contrary, straighten. For a long time, the keratin straightening procedure helps to give the hair perfect smoothness and a well-groomed appearance. However, this manipulation adversely affects the health of the hair. This is due to the fact that safe substances are not always used for the procedure.
To obtain a tremendous effect while maintaining curls in a healthy state, it is recommended to use keratin hair straighteners without formaldehyde.
They do not adversely affect strands.
The effects of formaldehyde on humans
Formaldehyde is a transparent toxic gas. It is actively used as a preservative in cosmetic preparations, it is considered permitted and safe for use in an acceptable amount of up to 0.2%. In the process of keratin straightening, formaldehyde plays the role of a catalyst in the implementation of chemical processes. It destroys disulfide compounds in the structure of the hair, due to which it straightens it. However, in Europe this substance is considered carcinogenic. Specialists even find a direct causal relationship with the onset of cancer pathologies. Periodically, there are cases of the appearance of diseases of the nervous, respiratory and reproductive systems, as well as various skin diseases, both among stylists and their clients.
Unfortunately, all keratin straightener formulations contain formaldehyde, only in various forms. That is, when purchasing a drug that says "without formaldehyde", it is worth considering that this is not entirely true. That is, formaldehyde may not be present in the product in liquid form, but when the strands are heated, it may appear in gaseous form. Safer non-formaldehyde preparations for rectification contain aldehydes and aldehyde acids, which under the influence of high temperature are transformed into formaldehyde. Such compositions have a less lasting effect, but are more sparing.
Procedure technology
The technique for performing this procedure occurs in stages. First you need to wash your hair several times with a special cleansing shampoo, which allows you to remove the remnants of various care products from curls. Such washing allows you to open the scales of the hair shaft and make its structure more loose. Then, along the entire length of the hair, with the exception of the basal zone, a composition containing liquid keratin is applied. The product is left on strands for half an hour.
Then the hair is dried using an iron, heated to 230 ° C.
When heated, keratin protein “envelops” each hair, which makes the curls even and more resistant to various negative environmental influences.
For additional hydration and nutrition, a special hair mask is used. After the procedure, the smoothness effect can last up to 4 months. It is worth noting that immediately after keratin straightening (up to 3 days), it is not recommended to wash your hair and use various accessories.
In pursuit of beauty, many women face a difficult choice between health and a chic look. Fortunately, innovative technologies in hairdressing allow the use of means for keratin hair straightening without formaldehyde, which does not cause harm to health.

Advantages and disadvantages of formaldehyde-free alignment
One of the positive aspects of using a formaldehyde-free keratin straightener is its minimal effect on the hair structure. When using such preparations, the disulfide bond does not break, but stretches, which is confirmed by the return of the original hairstyle after the end of the leveling effect. As for formaldehyde agents, after washing them, the curls look noticeably worse, and it is almost impossible to restore them.
The next advantage of non-formaldehyde cosmetics is a health-improving, strengthening cumulative effect. After several keratin smoothing procedures, the hair is almost completely restored.
The need for another straightening is eliminated by itself.
Of the shortcomings, the high cost of the procedure is most often noted. It is due to the high percentage of the main ingredient (keratin), which in itself is not very cheap. Often, cheap hair straighteners contain keratin in very small doses (5-10%).
Many keratin straighteners have a pungent odor. In addition, they require a lot of time for the procedure (up to 4 hours). Unfortunately, there is a considerable risk of acquiring fake products. And finally, in some cases, the use of drugs without formaldehyde does not allow to achieve the desired effect. Usually this applies to girls with very tough and small curls.
When choosing a keratin hair straightener, it is recommended to consult a specialist in the hairdressing industry. It is important to consider the individual characteristics of the structure of curls and the desired result. Perhaps to achieve a “one-time” effect of straight hair and save money, it will be enough to use a styler or ironing. Although it is worth noting that the result of a larger financial investment will achieve the longest possible effect of healthy and even strands.
