Japanese smoothing and straightening aka Yuko System

How Japanese Straightening Works ?

Japanese straightening, also called Yuko System, belongs to the category of permanent smoothing, hair straightening. Unlike Brazilian straightening, it is not a treatment but a process intended to permanently straighten the hair.

It is considered to be one of the most sweeping smoothes on the market today.

Like its little brother Korean straightening the hair, Japanese straightening is based on the application of a product that aims to break and deeply modify the natural structure of the hair to eliminate frizz.

It is applied after having opened the micro scales of the hair with a special shampoo. The product is then fixed by the heat of ceramic heating plates (hair straighteners).

What are the ingredients in Japanese smoothing products ?

Japanese straightening is divided into two stages, the first of which is thiol-type straightening. This is achieved with a cream that contains ammonia and thioglycolic acid.

These two components make it possible to remove approximately 30% of disulfides, these small atoms which bind keratin and give its structure to the hair.

Ammonia is a product widely used in the hairdressing sector, especially for coloring and straightening. Here, it acts as an alkaline agent, essential to activate the action of thioglycolic acid.

Ammonia is undoubtedly one of the most effective agents when it comes to altering hair structure. Its main drawback is its very strong odor, and the fact that it is very volatile.

The cream used in Japanese straightening also contains silk proteins, the main function of which is to protect the hair to compensate for the other two rather aggressive ingredients.

silk proteins have a sheathing and strengthening effect on the hair. They promote water retention in the hair, leaving it hydrated and soft to the touch, even after straightening using chemical compounds.

Who can do a Japanese smoothing ?

Japanese straightening adapts to all types of hair, whether it is naturally wavy, curly, frizzy or even frizzy. The result will be the same for all, namely very straight hair, similar to Asian type hair.

Japanese straightening is possible on short hair, male or female, as long as the length is at least 4 centimeters.

Japanese straightening can also be done on colored hair. On the other hand, it is not recommended on highlighted or already weakened hair. Indeed, for Japanese straightening, quite aggressive chemical compounds come into play and could damage the hair fiber even more.

Finally, Japanese straightening being a permanent straightening which aims to modify the very structure of the hair, it is not recommended for children and adolescents under 15 years old. As their hair has not yet reached its final shape, Japanese straightening could compromise its good regrowth and good development in the future.

Due to its chemical components, Japanese straightening is also not recommended for pregnant women.

What precautions should I take right after my Japanese straightening ?

As with all hair straighteners, whether Brazilian, Korean or Japanese, special care should be taken during the first few days after the procedure.

For Japanese straightening, it is forbidden to tie the hair or put hair clips on it for the first 48 hours. The risk is that your hair will retain the shape created by a rubber band or clips.

During these first two days, you will also need to avoid humidity and therefore not wash your hair.

If your hair gets wet accidentally, because of the rain for example, you can make up for it by passing a straightening iron on the strands concerned.

What results can I expect after Japanese straightening ?

The results of the Japanese smoothing are truly stunning, and everyone agrees on this point. No matter what your hair is, it will come out smoother than ever. Japanese straightening keeps its promises with a "drumstick" result that approaches Asian-style hair.

The smoothing is of course resistant to water and humidity, that is to say that you can take showers, go to the pool or the sea, sweat in the gym, or dance in the rain without your frizz reappearing!

The healthier your hair originally, the more aesthetically pleasing the result will be. Indeed, already damaged or weakened hair may come out of a Japanese straightening with an even more brittle and dehydrated appearance.

A professional hairdresser should also refuse you a Japanese straightening if your hair is too damaged.

How to maintain my hair after Japanese straightening ?

As with all straightening, it is advisable to adapt the products you use in order to keep your hair healthy.

Thus, avoid shampoos containing sulfate or sodium, ingredients that could affect the result of your straightening and the health of your hair.

You can also apply keratin treatments to your hair on a regular basis. This protein, naturally contained in the hair, will allow them to maintain their elasticity and shine over time.

What are the benefits of Japanese straightening ?

The main advantage of Japanese straightening is its perfect straightening, which lasts a very long time: the first touch-ups are necessary at the roots after 6 months, but the lengths are still just as stiff. This is valid even for thicker or curlier hair, such as frizzy afro hair, which reacts very well to Japanese straightening.

Another advantage of Japanese straightening is the high concentration of silk proteins in the straightening product. These help protect the hair against the aggression of ammonia and thioglycolic acid, and make it strong, soft and shiny. Contrary to popular belief about Japanese straightening, this one is actually not harmful to the hair.
