19 What IS a Japanese Straightening Service?
Japanese Perm, thermal reconditioning, straight perm, bio ionic hair retexturizing, high-tech perm. What
do all of these names have in common, you ask? They are all different names for one service: Japanese
Hair Straightening service.
A Japanese Hair Straightening service is slightly similar to a Brazilian Blow-out, but more like a reverse
perm. After having this service performed, you will have permanent pin-straight hair until it grows out.
In this article, I will answer all of your questions, like “How is it performed?”, “What are the different
types?”, “Does it work on African Hair?”, “What other types of hair does it work on?”, “Are there any side
effects”, and “How much does it cost?” When you are done reading this, you will know everything there is
to know about Japanese Straightening.
Because of these negative issues with the Brazilian Blow-out, I decided to write about a safer alternative,
which is the Japanese Straightening system.
What is it?
Japanese straightening is a new technology, which obviously
originated in Japan, that is used to make frizzy, curly, or wavy hair
pin-straight, without damaging the hair. The process is
permanent, meaning it will not go back to curly on its own, but
you need to get the regrowth touched up about every 6 months to a
year. It is suitable for almost every type of hair.

It is also known as thermal reconditioning, straight perm, bio ionic
hair retexturizing, high-tech straight perm and Japanese straight
What is the process to perform a
Japanese straightening service?
1. First the hair is washed with a sodium-free clarifying shampoo. This is done with any other service that
changes the shape of the hair, to remove build-up from medication or products.
2. After the hair is rinsed, solution is applied to small sections throughout the head, but not applied to the
scalp. This solution is a thioglycolate (called retextuizer) which is the same type of chemical used for perms,
and is used to break down the protein bonds in the hair and can process for up to 40 minutes under a dryer
3. When the hair is dry, a very hot ceramic flat-iron is used to straighten each tiny section of hair.
Subsections should be about 1/8 of an inch. This process could take a lot of time.
4. When hair is completely straight, a neutralizer is applied to the hair, to help rebuild the protein bonds in
their new shape. At this point, the hair is stretched to make it very straight, and then the hair has to dry
5. Lastly, the hair is shampooed, blown dry and flat ironed again. Then voila, the Japanese straightener is
Are there different types of Japanese straighteners?
Yuko was the original form of Japanese straightening. It was not recommended for African-American hair
or different types of chemically treated hair.
Liscio is the newer form of Japanese straightening, made in 1996 and it is safe for all chemically treated
hair. It is most commonly used today.
How long will the procedure take and how much does it cost?
The treatment usually takes between 3 and 6 hours and runs about 300-600$. This is because the product
is expensive for hair stylists and you are paying for their time.
What type of hair is this process good for?
The Japanese straightening system will work for almost every type of hair. It will work wonders on African
hair, and works for a lot of color treated hair. A consultation will be needed to make sure your hair can
handle it. I would not recommend having this procedure done on overly processed hair. It can NOT be done
on previously relaxed hair. Also, remember that everyone’s hair is different and may produce different
What can I do to maintain my hair after having this process
You cannot wash your hair for 72 hours after having this done. This allows your hair to set. Along with not
washing it, you should try not to let any moisture touch your hair. This means no sweating (no exercise).
Also, you will not be able to do anything that will kink your hair during this time period. Examples of kinks
are putting your hair in a pony tail, putting your hair behind your ears, wearing hats or glasses, etc. Since
this process can damage your hair, you will want to recondition it often and try to use a wide-tooth comb to
What are some side effects?
-If a few hairs are missed during the process, they will stick out and be frizzy.
-Shine and moisture is said to fade with time.
-It is expensive to maintain, since you will have to retouch it every 6 months.
-Hair appears to be thinner than when it was curly.
-Your hair will never hold a curl.
-Hair will be damaged.
What is the difference between a relaxer, Brazilian blow-out,
and Japanese straightener?
Relaxers burn the outside shaft of your hair, so it looks dead and limp afterwards.
Brazilian blow-outs are not as permanent and effective. They are made mostly for frizzy hair, and they don’t
completely straighten your hair. They work on any type of hair, even overly processed hair, but
formaldehyde is the main ingredient and can contribute to health problems.
Japanese hair straightening completely transforms even the curliest hair into pin-straight hair. Hair is left
completely straight, and feeling silky and smooth with a glossy appearance. It is the most permanent type of
