Keratin hair straightening is one of the most popular procedures in beauty salons, which allows you to smooth and straighten unruly and wavy hair for a long time. This method has become very popular among women who want straight and silky hair without constant effort and expensive daily styling procedures. In this article, we'll look at what keratin hair straightening is, how it works, its advantages and disadvantages, and tell you how to maintain the results of this procedure for a long time.

What is keratin hair straightening?

Keratin hair straightening is a cosmetic procedure that uses a special formula with keratin to smooth and straighten hair. Keratin is a natural protein that is the basis of hair structure. During the procedure, keratin is applied to the hair, penetrates the cuticle and fills in damaged areas. This helps to lock the keratin inside the hair and makes it straighter, smoother and more manageable.

The keratin hair straightening procedure is usually performed in beauty salons by specialists. It can take several hours, depending on the length and texture of the hair. After applying the keratin mixture to the hair, it is straightened with an iron at a high temperature, which helps to fix the keratin and provides a longer lasting effect of the procedure.

Keratin hair straightening is aimed at reducing fluffiness, waviness and unruliness of hair, which facilitates the styling process. As a result, the hair becomes straighter, smoother and softer to the touch. The procedure can also help restore damaged hair by filling in the damage and restoring its natural structure.

It is important to note that the effect of keratin hair straightening is temporary and usually lasts from 3 to 6 months. The duration of the effect may vary depending on the type of hair and its maintenance after the procedure. Regular care and the use of special hair care products after keratin straightening can help maintain its duration and quality.

The keratin hair straightening procedure includes several stages:

  1. Before the procedure, the hair is washed with a special shampoo that deeply cleanses the hair and opens the cuticle, preparing it for better penetration of keratin.
  2. A keratin mixture is applied to the dried hair, which is evenly distributed along the entire length of the hair.
  3. After applying the mixture, the hair is straightened with an iron at a high temperature, which allows you to lock the hair keratin inside and creates a barrier that protects the hair from external factors.
  4. The final step is to wash off the remaining keratin and apply a fixing agent that fixes the results of the procedure.
