Straight hair remains one of the great hair trends. Beyond gorgeous curls or beautiful waves, polished manes became one. compulsory season and there are many celebrities joining it. Therefore, there is nothing like finding a cure for the permanent ones where you can enjoy the most extreme smoothness. Japanese straightening.

so we talked Javier Ruiz The manager of the Hermanos Ruiz salon in Logroño explained to us everything we need to know about Japanese straightening, a technique that is still on the cards in many salons.

The first thing Javier told us was that, as the name suggests, it’s a form of Japanese softening. Technique created in the late 90s It was introduced in Spain at the beginning of this century to achieve a precise straightening. In fact, it was one of the most requested techniques of that time, with impeccable results that we can boast above all. Permanently smooth, straight and silky hair for several months.


What type of hair is Japanese straightening recommended for?

Diagnosis should always be made weeks in advance to ascertain the condition of the hair, know if it can be done, what product strength it is made with, and advise the client to moisturize frequently before the service day.

Therefore, according to the specialist we consulted, it is best to let us advise according to the condition of our hair, but in principle, this straightening is indicated for all types of hair, but it is also true that it is true. Not recommended for those who have been bleached before. And throwing in is a very aggressive technique in itself, so combining the two is not desirable.


We will also take into account that if our strands are slightly damaged, we may need strands of hair. repair pretreatment and if you have dyed hair, you should wait at least 2 weeks from the last application.

In any case, the hair for which this type of treatment is most noticeable is the most curly or very voluminous Those who want to achieve a long-lasting smoothness. In fact, according to experts, it is a technique used today. It is used a lot for afro hair.

The first thing to note is “This is a special salon technique He can’t be done at home and it should be done by a professional trained in this technique, because without knowing how to iron and without time control, hair can burn”. In fact, very advanced products should be used to care for hair with a highly moisturizing content, leaving the hair more shiny and elastic, because it is a conditioning treatment. It can be considered very aggressive if not done properly.


After initial diagnosis, we were going to the service He “it consists in applying suitable emollient cream (There are 3 strengths, natural hair, dyed hair and up to 30% highlights). The application is made in very thin sections and at a distance of 1 cm from the root. Hair should be in a completely vertical position. Time is left according to the selected strength. It can vary from 5 to 25 minutes. It is then rinsed thoroughly. A treat below wellaplex It is left to act for 5 minutes, rinsed, and the amino acid chains to regenerate. Ironing process is started in very thin sections and not exceeding 180⁰. It also requires a step of 2 to 3 passes from the wick with small touches, this step is very technical and takes a long time compared to the hair. This closes and smoothes the cuticle. It is then neutralized to sealed correct and finally stabilized with Wellaplex step 2 for 10 minutes.”

This whole process will take us 2 to 4 hours depending on hair quantity, length and other factors.

What is the price of Japanese straightening?


The cost of this type of treatment varies depending on the time (2 hours is not the same as 4 hours, this is explained in the consultation) and is between 175 and 300 Euros.

With this we arrive at a conclusion that is permanent in principle and only grows, that is, takes shape from the root. Of course, as Javier warned us, “In some cases, it can take shape due to the type of hair or if it’s not done properly, but it straightens easily with an iron”.

How long does Japanese straightening take?

Yes, we want to know, how much can we boast of a perfect straightening? Well once again it will depend on each hair so guess three to six months.

In any case, he tells us that it is recommended after treatment. let’s not use rubber bands and similar things on the hair for a few days and then we use high quality products for curls, shampoo, conditioner and mask once a week 2 times a week and they recommend us. High quality professional products such as the System brand, especially the Smoothen series.

What is better keratin or Japanese straightening

As we commented and other professionals such as Kenzo Yonekura from Peluqueria Krown in Madrid, this treatment was in vogue in the 90s and early 2000s, but technology has advanced a lot in this regard and we find other newer ones more recommended and less frequent. aggressive as they are, exactly one keratin.

Of course, he tells us that even keratin can become obsolete in the face of others that are much less aggressive and equally effective. Capillary botox or a bioplasty costing between 90 and 180 euros, depending on the length of the hair. Come on, it’s cheaper as well as being more respectful.


Why is Japanese straightening no longer fashionable?

Having said that, although there are salons that continue to use this technique, it has been left behind by many more recommended for hair.

Also, as Kenzo tells us, one of the biggest downsides to this straightening is: no kickback that is, after a short time we find ourselves more voluminous, curls, etc. If we want to see it, it won’t be possible until our hair grows back. And Japanese straightening breaks the inner structure of the hair at the root, which means that it does not allow us to change what we can return in a certain way with other types of treatment.

As we can see, it’s a somewhat archaic cure that we can still find, but there are much more interesting alternatives to it.
