Japanese hair straightening.

Japanese hair straightening

Japanese hair straightening, also known as thermal reconditioning, is a hair treatment that leaves your locks looking perfectly slick and wave-free to grow out , treatment uses a cysteine-based chemical solution to break the bonds and reconfigure the natural structure of the hair from the inside out.

The process dates back to the 1990s, when Japanese hair expert Yuko Yamashita patented the method. Since then, it’s become a popular method for dealing with all types of wavy, curly, frizzy, or generally unruly hair all over the world.

According to the team at Jeju Hair in London, “It’s been popular in countries such as Japan and South Korea for more than 20 years. It’s also now popular in many other countries.

Japanese hair straightening.

Getting any kind of permanent treatment may initially seem a little daunting, so it’s always important to fully understand the process.
With Japanese hair straightening, a chemical solution containing cysteine is used to “change the structure of the hair permanently,” Moodie explains.
 
The process, from start to finish
 
  1. The cysteine solution is applied to the hair.
  2. The solution is left on the hair for 20 minutes. During this time, a chemical process disables bonds in the hair.
  3. The product is washed out.
  4. The hair is prepped with conditioning treatments that will keep it hydrated and strong throughout the process.
  5. Small sections of hair are passed through a hair straightener at 180°F (82°C) or lower for damaged hair.
  6. After the hair is fully ironed straight, then it needs to be neutralized with another solution. This takes approximately 10 minutes.
  7. The neutralizer is rinsed out.
  8. The hair is blow-dried without the use of styling brushes.

Aftercare

As with any treatment, it’s important you take good care of your hair after the treatment to ensure you get the best results and don’t damage your hair.
 

In the first 72 hours

In the first 3 days after getting your treatment, your hair will need some special care.
  • For 3 days, keep your hair completely dry.
  • Avoid showers, rain, or even sweat.
  • Avoid any hair products such as oils, gels, or dry shampoo.
  • Try to keep your hair as straight as possible by leaving it down and keeping it untucked from the ears.

In the first 72 hours

After the first 3 days, the treatment should set, and, for the most part, you’ll be able to go back to your normal hair routine.
A few exceptions include:
  • Avoid chlorinated water for a few weeks.
  • Avoid too much sun exposure.
  • Avoid sulfur-based shampoos. If possible, use products that are designed for chemically straightened hair.

Check with your hair specialist about which hair products are best to use.

Cons

  • The hair may appear thinner, leading to a less appealing look for some.
  • The procedure can be expensive, potentially out of reach for many.
  • Regular touch-ups required may not restore the initial body or shape, which can be disappointing.
  • There is a risk of damage if performed by an inexperienced stylist, so it’s advisable to conduct a strand test before proceeding.
Pros
  • You’ll spend significantly less time getting ready each morning, allowing you to devote those precious minutes to other important activities or simply enjoy a more relaxed start to your day.
  • You won’t have to worry about your hair getting wet during the day: with this method, your hair will naturally air dry straight, which means no more frizz or awkward damp hair occasions!
  • Your hair may feel and look healthier in the long run, as you won’t need to rely on heat styling tools on your hair every day; this helps to preserve its natural strength and shine.
  • You’ll still have the flexibility to style your hair using a curling iron if you choose to, so you can easily switch up your look for special occasions or simply to feel a bit different without causing damage.
The procedure will probably take around 2-3 hours. The initial consultation and strand test will also take about an hour.
The procedure is permanent, but as your hair grows out, the roots will need to be touched up.
Eventually, you’ll be able to grow out all of your straightened hair. Alternatively, you can opt for a touch up around every 6 months to maintain the look.
Most salons will charge from around $400 to $800 for a single treatment.
In the first few days after the treatment, it’s important to keep the hair as straight as possible.
To avoid getting kinks in your hair after the procedure, keep your hair down overnight instead of tying it up.
Try to lie on your back with your hair splayed out on the pillow beneath your head.
  • While the mention of chemicals may sound a little frightening, Japanese hair straightening is generally safe for most people when it’s done correctly.
  • In the long run, it can even improve hair health because you’ll likely use fewer heat styling products.
  • Still, there are always risks when using intensive chemical treatments. For some people, straightening may present even more risks.
  • For instance, if you’ve already had chemical treatments or if your hair’s been coloured, you may be more likely to experience hair damage from Japanese hair straightening.
After the initial aftercare period, which usually lasts around 3 days, you can use any kind of hair accessory.
However, for long-lasting results, try to use soft, gentle accessories that don’t cause harsh kinks in the hair.
Most stylists advise against washing the hair until 3 days after the treatment.
After your first wash, your hair should be straight after being blow dried or air dried.
It’s important to find a reputable, licensed salon.
In general, it’s probably smart to begin your hunt for the perfect salon in large cities. Many experienced hair stylists tend to gravitate to pricier, well-known salons in major metro areas, though this isn’t always the case.
Be sure to check reviews and testimonials and, if possible, before and after pictures. And don’t forget to do a strand test first!
No, only trained professionals with the right tools and skills are able to perform the treatment.
Japanese hair straightening is a permanent process, so no, you can’t undo the procedure.
Once you’ve chemically straightened the hair, the structure of the hair itself is permanently changed. The only way to regain your old texture and shape is to let the hair grow out.
Unfortunately, if you’re unhappy with the results, waiting is the name of the game.
It may take a year or 2 before your hair fully grows out. Keep getting regular trims to help your hair grow out more quickly.
A “relaxer” is another permanent hair straightening treatment. Like a Japanese treatment, a relaxer works by changing the hair’s internal structure.
The process involves using a relaxer formula, which usually contains sodium. This treatment is usually recommended for people with extremely kinky hair, while the Japanese treatment is recommended for those with softer curls or waves.
Japanese hair straightening can be a great option for some people who want to manage their frizzy or curly hair.
However, the procedure involves strong chemicals, so make sure you do your research and prep for careful aftercare before diving in.
Make sure you find a reputable, experienced professional to provide the treatment, and follow after procedures closely.
