Yuko Hair Straightening System

Yuko Hair Straightening System smoothes curly, dry, unruly hair permanently with a revolutionary straightening system that uses heat to restructure the hair's protein bond. The result is smooth, sleek, shiny, straight, regenerated (repaired) hair!

The protein-based professional Yuko System uses a specially-designed, patented heat iron set at over 300 degrees to seal in moisture once the cystine bone in the hair is cut off, allowing hair to be molded into any shape. Heat consolidates the straightening process - REPAIRING and REGENERATING hair. The shine and softness are evident. Salon professionals and the customer both love the system's results.

Ms. Yuko, who created the system in 1996 with the intent to create a non-coating, straightening system that uses the heat oxidation process to seal in and rebuild hair from the inside out. One of the Yuko steps includes using shark oil on hair and also using steam instead of direct heat to condition hair.

Both an unconventional idea and a breakthrough in the art of hair straightening, the Yuko Straightening System actually uses the hair's small amount of "living body electricity" to cut off the hair's cystine bone, reshaping it to appear straight. This goes against the notion that straightened hair is damaged hair: the result is hair that can breathe from a lack of coating, and a hair shaft that is rejuvenated for the first time. If desired, the Yuko process can be reversed to obtain natural curls again.

Yuko Hair Straightening System FAQ

Q: How many touch-ups do you need and how long does the process take?!

A: Expect to have the process done at least twice a year. Long hair takes four and a half hours to be processed. Short hair is about three hours.

Q: How long does the YUKO straightening last?

A: Once the hair is processed it is permanently straightened. There are NO traditional waxes used, therefore time does not "wear down" the process. The straightening comes from a re-structured protein bond inside the hair shaft.

A: It is safe for a child as young as twelve years old to use the process.

Q: Can senior citizens use the YUKO SYSTEM?

by Rachael from UK on Oct 16, 2009

I am getting my hair straightened with the Yuko system on Wednesday afternoon and am going in holiday on the Friday, to Thailand. When it is advisible to wash my hair? After the flight when I arrive at my destination? Will it look really greasy by then? Do you think I need to take hair straighteners with me on my trip. Advice appreciated. Also should I straighten my hair before my appointment or just go with it natural and frizzy? Thanks.

Hey Kaya- I just had my hair done too (I'm a few posts before you.) My hair was kinda greasy too, but I'm stopped using the type of shampoo that I use to use when my hair was wavy. It has alot of oils in it, to help control frizz, but now that you have your hair straight...I don't think you need all the conditions/ oil. Try a different shampoo, and limited conditioner and see if that works. GOOD LUCK!

by kaya from Ft. Lauderdale FL on Sep 8, 2009

someone please answer. I just got the Yuko system done and follow up all the instructions. My question is: is it normal that the hair is very greasy after or the treatment was done incorrectly?
Thank you

by Sue from Letts, Iowa on Sep 7, 2009

Is there anyone in Iowa that does the Yuko system at their salon and knows what they are doing?

by Curlygirl from Lexington, KY on Sep 6, 2009

TOTALLY SATISFIED!!! I lived in Taiwan for 2 years and had my very long curly hair straightened several times there....but once I came back, I didn't think I'd be able to find a Japanese straightener that I could afford. I went to Tara at Planet Salon and I could not be happier!!! She was patient, attentive....and spend the time necessary to really do the job right!! I could not be happier! The cost was $100 per hour. Based on your hair....it could take one-three hours. It took 3 for mine, but worth every penny! In the past this process has lasted at a minimum, 6 months....so...let's hope the Yuko straightener does the same!

by UK Hair Expert from London on Aug 26, 2009

I am not only a trained Yuko stylist but also a hair expert and work with several companies. I will try to answer most of the question put forward about Yuko.

Firstly (done in the right hands) Yuko is an incredibly good straightening system which lasts. However, it is not suitable for all types and results depend entirely on the stylist/technician applying the system. Although Yuko uses very rich proteins in their products in actual fact the technology of the system is nothing revolutionary. Its really nothing more than a thio based perm solution a neautraliser and a heat controlled titanium plated flat iron. The skill executed by the stylist requires two elements:- 1) The hair is sufficiently softened and straightened out when the thio (step 1) solution is applied. If the hair is still curly after you rinse this solution the flat iron won't rid the hair of all the movement. 2) To get exceptional results the hair has to be ironed in a specific way in very tiny sections. You also can't slide the iron down the hair as the shaft will emit steam and if you slide the iron the steam becomes trapped in the cortex and bursts the hair damaging it. Instead you have to smooth with a patting motion on each super thin section of hair releasing clouds of steam. When the section of hair has 'fixed' straight you'll know because it will become static - this means you can move onto the next section. The whole ironing process is dull, boring and time consuming and is the reason salons charge so much money for the service. Once the hair is ironed super straight you then apply a neautraliser to the newly ironed dry hair. This will then permanently 'fix' the hair in it's super straight state.

Yuko system works best on virgin hair (hence the results you see on the net look so good). On hair with a colourant that has only darkened or deposited colour you will also get good results. It doesn't work well on highlighted or bleached hair and is also not suitable for afro Caribbean hair because the thio solution isn't strong enough to penetrate the cuticle of this hair type and using a Lye relaxer will result in breakage when ironing.

If you are wanting it, have good hair (that fits the above) and especially if you know a sucker who will following the ironing rules and spend hours ironing out tiny flat sections of hair as outlined for you! You can do the system at home yourself. You will need a good (expensive) ceramic straightener with heat control (of 230) borrow one if you don't have one! To do at home you will need:-

1 bottle of a strong stripping/clarifying shampoo (something with few proteins in but maybe has sodium chloride or Potassium as a main ingredient)

2) Coconut Oil (or a conditioner with a very high coconut oil content - but pure oil is best)

3) A home perm kit for normal hair (not a foam perm! and buy two boxes as you will need more solution than roller wound perming).

4) Flour to thicken perm solution

5) Mineral Water and a water spray

6) Plastic sectioning clips and a plastic comb

7) A tint bowl and brush

8) A silicone serum or spray

9) A very good set of irons ceramic plated with a temperature control (of 230 ish).

10) Plastic gloves

Step One

Wash your hair in the clarifying stripping shampoo. The Sodium chloride will strip the cuticle of product and build up and ensure the perming chemicals can enter your hair. Give two washes - the hair will feel dry and tangled afterwards so make sure you comb carefully.

Step Two

Lightly Towel dry the hair but keep in as much moisture as possible, section the hair into four using the clips (two sections at the back, two at the sides).

Step Three

Pour some perming solution (part 1 or a in the home perm kit) into the tint bowl and add small amounts of flour, keep stirring with the tint brush to create a smooth cream. Keep adding solution and flour in small quantities to avoid lumps. beware the solution stinks!!

Step Four

Once you have a thick, smooth cream and using the tint brush (and wearing the gloves) start applying the perm solution to each section of hair (avoiding the near root areas as much as possible), sub dividing the section and combing the hair very smooth. This stage is vital as the hair is now re-forming into a straight shape. So make sure you comb each sub section super smooth and very flat. This is why your perming solution needs to be thickened - as the cream will support the straight direction you pull the hair in.

Step Five

Once all your sections and sub sections have been covered in perming cream and are smoothed out straight gently cover each section in cling film to trap the heat inside. You will need to apply the cling film in long strips on each section to avoid kinking the hair which needs to be kept super straight. If a section does twist, just re smooth with hands and cover with cling film strip.

Step Six

You will need to develop in a (non cool or cold) room for 20 minutes (for normal hair). Once the 20 minutes is up remove and discard the cling film and rinse the hair with warm water for at least five minutes, after 5 minutes apply a very small amount of the shampoo (used prior) to the hair and lather. This will remove any excess perm solution residue. Rinse again for several minutes and then gently dab off the excess water with a towel.

Step Seven - Adding Protein to the hair

The hair should now look straighter but feel tangled and dry. At this stage you can add protein to the hair as the cuticle is open. This protein will then become trapped inside the hair when you iron. To do this, wash and rinse your tint bowl and brush with the shampoo (to remove perm residue) and pour in around 50ml of Coconut oil into the bowl. Section the hair and apply the coconut oil in exactly the same manner as you did the perming solution, ensure you really comb the coconut into the hair. Coconut oil is rich in proteins and will enter deep inside the cortex and replenish lost moisture. Once applied continue combing the hair through very gently for 10 minutes keep removing any excess coconut oil by wiping the plastic (tangle) comb. Remember your hair has been unlocked by the perming solution so is in a fragile state do not pull the hair.

Step Eight

After 10 minutes give the hair a very light rinse with cool water to remove any excess coconut oil. However you should only rinse for 1 minute as you don't want the coconut to be stripped from the hair. As before towel blot and re-section.

Step Nine

Now for the long stage!! Fill your water spray up with mineral water (Evian or Volvic are fine), using mineral water on the hair will ensure it's nourished and free of tap water chemicals. Spray each section with the mineral water as you clip the section into place (as originally outlined).

IMPORTANT!

The ironing stage takes quite a while and sections can dry out! NEVER EVER allow the hair to dry out always keep un-ironed sections wet by spraying with water and pinning tightly away. When hair dries (after a perming solution has been applied it can set due to the oxygen in the air!).

Now you should have four wet sections securely pinned up with clips. Starting at one of the back sections, remove the clip, take a hair dryer and gently dry the section 80% using a smoothing motion with the tangle comb or a gentle brush. DO NOT PULL THE HAIR. Once the hair is 80% dry you can begin ironing. Sub divide the section into very thin panels and with a heat up to 230 (depending on hair density) start at the root and start patting the iron on each part of the section to remove steam. When the sub section is entirely dry and goes static you can move onto the next sub section.

This is a long process, you can take thicker sections but the results will not be flat and silky just fuller and straight. I would recommend small thin sections only. Each main section (of the four) will take you some time to complete. Always make sure you gently moisten the un-ironed sections with the mineral water to stop them drying out. Never wet them so much they drip as this could re-dampen your ironed section and undo your work!!

Step Ten

Once you have ironed each section you will finally see very silky smooth hair. At this stage you can go over the whole head with a smooth (traditional) sliding iron motion to finish this stage off. Now you must re-section the hair and apply the neutraliser to each section. I would apply the neutraliser directly from the home perm kit applicator bottle supplied. Be careful you apply the neutraliser to every section and piece of hair. The neutraliser is now fixing the new straight pattern you have set into the hair so it's vital you cover every area. Be warned - dry hair eats up neutraliser so apply slowly and carefully - always make sure you have 2 kits (thus two bottles of neautraliser) and comb the hair as you apply to insure your new straight hair is fully covered. Leave the neautraliser to develop for 10 minutes.

Step eleven

After the neutraliser has developed for 10 minutes you can rinse the hair with tepid water. After rinsing for maybe 3 minutes apply a tiny amount of coconut oil to the wet hair - leave for 1 minute and rinse. After rinsing for a further 2 minutes your hair should feel cleansed and soft.

Step twelve

Your hair is now straightened. To finish, towel dry and comb smooth, apply some silicone based serum to the wet hair, comb thoroughly, section the hair back into four and gently dry each section with the hairdryer. At this stage you will notice the hair is straight and drying nicely. Once all sections are dry you will need to do one final (and quick) ironing. Here you iron just as you would normally. Sliding down large sections of hair from root to tip. During this stage the silicone is being sealed onto the hair and creating a protective layer which will guard the hair over the next few days as it sets permanently. However the ironing should take no more than ten minutes or so.

Remember you can't wash, wet or style your hair now for three days. As the neutraliser needs to fix into the hair. If the hair becomes wet dry and iron again immediately (as outlined in stage 12). Because of the coconut oil the hair should feel soft and smooth. Just remember you need to follow every step exactly to get good results. However this is a Yuko System!

by receptionist from CA on Aug 25, 2009

I used to work as a receptionist at a hair salon and got to see the Yuko method first hand. It works extremely well, and hair ends up looking as if you were born with straight hair. It is not damaging at all. The hair ends up very smooth. It takes a lot of time and requires a lot of patience from the hairdresser. He or she needs to pay very close attention to iron your hair straight or else you will not have the results you want. I highly recommend it!

You will only need to retouch when your roots grow out. If you have long hair, you can even wait a while longer as your your hair will usually weigh down the roots for an extra month.

by Lavinia from Brooklyn, New York on Aug 25, 2009

I have thin, but coarse hair. Iwould love this treatment as long as it does not flatten my hair too much. Do you have infor about a new york office that really knows how to do this yukon treatment?

by Izbit from Virginia on Aug 21, 2009

I am nearly 15 and trying to find a way to have straight hair for 9th grade. I am biracial (african american/white) and this sounds perfect. Do you think it is safe to have Yuko done on my hair, and if so, how do I find a salon that does it near my home?

by Suzaan Nel from South Africa on Aug 20, 2009

I am a hairstylist and I'm interessted to learn more about the Yuko Straightner. Can you please let me know. Thank You. Suzaan.

by Amber from Puerto Rico on Aug 10, 2009

I have done plenty of research on the yuko method, and would love to have it done. I am currently stationed in South Korea, does anybody know of a place that does it here??

by Gemima from scotland on Aug 3, 2009

I have had yuko done once before and was very VERY happy with the results. although it wasn't perfectly straight i was really happy with the results as it made it so much more manageable and quicker! more time to lie in in the morning! :)
I would like to get it done again but am a bit worried about the effects on the hair of getting the ends redone. I have heard that getting it applied on hair that has alredy been treated can cause hair to fall out. can anyone offer any advice on this??
also does anyone know of any good salons in thailiand? i am going there in sept and was wondering how much it migh cost there?
thanks in advance!

Hi,
Just wanted to share my experience. I had Yuko done for the first time about 6 years ago in the Yuko salon in London and have done it about once a year. It is incredible! I worked really well on me as I had no permanent hair colour. The first two years I had highlights and they were perfectly straightened (I have dark long coarse hair, wavy with a bit of frizz here and there). Every time it lasted about 6-7 months before I had to iron out the roots (the longer your hair is, the longer the effect as long hair tends to weigh down the roots so they don't show as much as shorter hairstyle). No side effect (I had L'Oréal x-tenso done once and my scalp was itchy for a good year plus the results were not as good, my hair got really dry and I had to chop it off every two months). It is expensive but worth it. Also if you do it in a salon that is not the official Yuko salon, make sure that your hairdresser uses the "right" iron to do the job. I had it done in a reputable salon in London and the girl did it with an iron that goes from wet to dry and the results was not as great. So make sure they dry the hair with a hairdryer and use a iron that just straightens (I think the temperature is very specific, your hairdresser will know about it). Hope that helps. Oh also, they say you should not wash for 48hrs which is crucial, I would say add a couple of days on the top of that if you can (obviously you have to live as a social outcast during that time!), I think it makes a difference. Good luck.

I heard about Yuko when I was searching online, but couldn't find anyone doing it in Toronto. I ended up went to a pretty good salon in Scarborough 4 months ago, they are specializing Japanese Hair Straightening, they did an excellent job on my kinky, damaged hair. My hair is now hassles free, I highly recommend this salon to anyone who would like to have low maintenance and shine hair like me. I don't have their phone number but you can easily find them by Googling "Salon on Brimley", they deal with all Nationalities. I paid $450 for my long hair. Not bad at all.

by Laura from USÁ on Jul 25, 2009

I've been getting my hair straightened with Yuko for over 5 years. The first few times I did it I had it done every 6 months but now I've stretched it out to about a year. I had really kinky, coarse, and wiry hair and Yuko totally made it smooth and manageable. It doesn't permanently fix the hair, and you will notice grow out. After my last straightening about 6 months ago I decided I wanted to wear my hair curly again, so I only blew out/sraightened my roots and let the ends curl and that worked great. Yuko is expensive but it is very much worth it and will make hair much easier to work with. It also makes your hair feel much healthier and stronger.

(If you do get it done, schedule the straightening on a weekend or on days where you don't care if your hair looks bad. You can't wash/sweat/or get your hair wet for 48-72hrs after the process and the hair will get very greasy and stringy after the first day. You will really notice the affects after the first few washings )

by mark from cincinnati ohio on Jul 19, 2009

I am a hair stylist and would love to learn the yuko hair straightening system. Where can I find a cl****on this and approx. how much does it cost? I also want to know after the classes, where can i buy all the products to do the hair straightening?

by Angelina from Toronto on Jul 16, 2009

I just had the YUKO treatment done! I've got dry, curly, kinky, rough, course hair (I can't think of any other horrible words for it), but now it's JUST like Chinese hair. AMAZING. Super expensive. Use Google to find a high-end salon near you that offers it, because the high price is more than worth it. She said it will last 1 year to 1.5 years. It's beautiful and soft and lucious and totally 'Wash & Go' Hair.

by samla from Germany on Jun 22, 2009

I have a question: I have done CHI-hair straightening for one year now and i wasn't very satisfied with the result, because my hair was still a bit waved.
Now after one year I would like to try the YUKO-hairstraightening.
Is ist possible to use it for the whole hair or only for the new touch ups?
I would be glad for a quick answer, because I have tommorow the date for the hair straightening.

Thany you very much!
