Welcome to the world of Japanese hair straightening, created by the visionary hairdresser Yuko Yamashita.

This innovative technique represents a significant advance in the hairdressing industry and embodies a highly specialized craft whose complexity is often difficult to understand for both clients and many European hairdressers.

Japanese hair straightening is a rarity in Europe, and for good reason:

It requires not only technical skill, but also a passion for the craft. As a Yuko expert, let me introduce you to the finesse and longevity of this unique technique – for breathtakingly smooth, healthy, shiny hair that inspires and impresses.

YUKO Japanese Hair Straightening

Yuko is suitable for healthy wavy to very curly hair.

The healthier the hair, the better the result. Hair that has already been dyed or chemically treated may also be suitable if it is only slightly damaged and has been well cared for.

Whether YUKO hair straightening is possible depends entirely on the current condition of your hair. The hair must be in a good state of moisture and nourishment. An elasticity test determines whether chemical hair straightening can be carried out. If the hair tears easily when it is stretched 1 cm, it lacks moisture. If, on the other hand, the hair stretches but does not bounce back, it lacks protein. In both cases, chemical hair straightening is not possible.

Yuko is not suitable for moderately to severely damaged hair. Bleached hair is the most damaged and will not survive this treatment! I recommend Progressiva Organic.

Plan this time.

The times given assume that you keep your head still and upright. Think of your body as a tripod and your head as a screen: Every movement extends the time. Constantly looking at your smartphone can significantly increase the time, especially if your head is constantly tilted downwards.

Yuko Yamashita is a Japanese hair straightening specialist.

She is the inventor of hair straightening and is considered one of the world’s leading hair experts.

Together with Phiten, YUKO developed a special process that is the envy of the hair industry.

All Phiten products contain traces of gold and titanium. Phiten is able to incorporate small particles of these metals into the hair.

Step by Step

Treatment

Every salon has its own method, but these are the general steps to permanent hair straightening.

Consulting

Determination of hair type, chemical history, dryness and degree of damage.

Shampoo & pre-treatment

The hair is washed and the appropriate pre-treatments are applied. The pre-treatments prepare the hair with the necessary nutrients for processing.

The process

The product is applied 1 cm away from the scalp and left to saturate the hair.

The hair is now relaxed and 80% smoother. The hair has very little elasticity and stretches very easily when the elasticity test is carried out – the hair is now ready to be rinsed out.

Rinsing out the cream

The solution is rinsed off completely. The hair is given heat protection and blow-dried.

Straightening

Ironing with the straightening iron creates a permanently straight shape.

It is important to pay attention to fine sections, which is crucial to ensure that the hair remains permanently straight. In total, each strand is straightened 3 times.

Neutralization and styling

Durch das Auftragen des Neutralisators wird das geglättete Haar konditioniert und finalisiert. Nach dem abspülen des Neutralisator wird das Haar geföhnt.

The Result

The time required for Yuko smoothing is 5.5 hours.

The follow-up treatments will then take 4.5 – 5 hours.

Whether after 3, 6, 9 or 12 months. The hair undergoes the same treatment as the initial treatment, the areas that have already been straightened are given a contoller to protect these areas.

Every Yuko customer can be sure that her hair will only be straightened by an expert.

Before stylists can buy Yuko products, they must complete a solid basic education and hands-on training at the Yuko Academy in London.
For this reason, Yuko is not very common in Europe.

This Yuko hair straightening is world famous, so Yuko is often used as a synonym by many stylists, even though these products don’t exist!

Tips for aftercare:

This thermal treatment fools clients into thinking that their hair is healthy again, and many tend to neglect their hair after the treatment.

In fact, the hair now needs to be cared for after every shampoo to maintain its healthy appearance.

Immediately after the heat treatment, the hair must remain dry and smooth for 48 hours.
They must now absorb oxygen for 2 days, you are welcome to straighten them with a straightening iron.

The new shape is only fixed after 48 hours.
For this reason, ponytails should not be worn and tucking the hair behind the ears should also be avoided as this can lead to kinks.

F A Q

Due to this high level of damage to the hair, Yuko Thermal Reconditioning is no longer possible! Regardless of how long ago it was bleached, these areas can no longer be treated!
Do you have High Lights?
A mixture of lighter colored hair mixed with the natural hair color cannot be treated because the hair has different needs.

Henna and plant hair color is a natural hair color that is extracted from the leaves. In contrast to chemical hair colors, henna does not penetrate the hair, but rather wraps itself around the hair strands. This creates a protective layer on the hair. This protective layer prevents chemical hair treatments from working properly or producing unwanted results. The chemical substances cannot penetrate the hair because the henna layer is in the way. In addition, there will be unpredictable reactions between the chemical substances and the henna, which can lead to chemical hair burn or uneven color results.

There are many salons in the United States, Australia, England, Japan and South Korea that offer Yuko services. But there are very few salons in Europe. Every Yuko customer can be sure that her straightening will only be carried out by an expert. Before stylists can purchase Yuko products, they must receive solid basic training and hand-on training at the Yuko Academy London. That’s why Yuko is not so common in Europe. This Yuko hair straightening is world famous, which is why many stylists often use it as a synonym, even though these products are not available!

Yuko Thermal Reconditioning typically takes between 4 to 6 hours, but may take longer for very thick/natural hair.

Hair that is treated with YUKO will remain straight almost permanently. However, new hair will grow according to its natural texture. We recommend that you get YUKO touch-ups every 6 to 8 months, but the interval will vary depending on your natural hair texture and how quickly your hair grows

You can wash or wet your hair 2 day after this treatment is done. Blow dry 100% after shampooing every time to maintain straightness

No. Color your hair at least 2 weeks before or after the straightening procedure. Applying both chemical treatments simultaneously will result in hair damage, so do them separately to avoid undesirable results.

If the previous hair straightening procedure uses the same chemical (Ammonium Thioglycolate) as YUKO straightening solutions, applying YUKO will not be a problem. Please contact both companies to make sure chemicals are the same. Even if both use the same chemicals, the YUKO hair straightening process may not fully work if the hair is badly damaged already.

Brazilian/Keratin treatments may contain hazardous chemicals which release highly carcinogenic gas. For more information on the danger of chemicals, please check OSHA Safety and Regulations.
