There are a lot of new smoothing treatments and straightening treatments on the market. Which is safe?
Japanese Straightening solution is an age old product but a New Technique developed in Japan in 2003 by Liscio. The active ingredient is Ammonium thioglycolate which has been used in the salon industry safely for 80 years.
It is never applied to the scalp, but kept 1/4 to 1/2" from the scalp to prevent breakage and protect the body from system absorption, scalp and follicles from direct damage. 100% of the solution is rinsed from the hair prior to ironing. The hair is neutralized with low strength hydrogen peroxide to ensure there is no active solution in your strands. You leave the salon with re-arranged bonds for permanently straight locks.
There are many brands on the market, but the success is reliant upon the straightening technician's skill and knowledge. Note: hair previously treated with a relaxer or home color is not safe to straighten. Your stylist should be very well experienced and be comfortable to say a client's hair isn't suitable for successful straightening. It is critical that the client provides the stylist with chemical history of hair which is to be treated.
Brazilian Blowout and GK Keratin Smoother are just a couple of the brands that fall into "Smoothers" category. Smoothers last 2-5 months and fall into two categories:
with Formaldehyde producing chemicals, a known carcinogen.
or with Glyocylic Acid which leads to kidney damage or acute kidney failure. You can read about that here which is the National Library of Medicine Forensic Science website. Both of these are ironed at high temperatures.
Brazilian and Keratin Smoothers are ironed ONTO the strands, essentially baking an "outer shell" onto each strand. This temporarily holds hair into a smoother look for up to 12 weeks, wearing off gradually during washing, brushing, even blowing in the wind when friction occurs against the "shell." This results in fine particles being breathed into the lungs and penetrating the skin when strands touch the face and neck. When the solution is heated, fumes with formaldehyde are breathed into the lungs and penetrate the skin of the operator during the service. Formaldehyde is a known carcinogen. Formaldehyde will no longer be manufactured or sold in the USA as of January 1, 2025 according to Federal law.
GK Smoother with Glyocyclic acid is ironed into the hair. The steam is breathed into the lungs and penetrates skin leading to kidney damage.
Relaxers contain Sodium Hydroxide which also a known carcinogen reported to cause uterine cancer in the client as it is applied to the scalp and is systemically absorbed. Sodium Hydroxide is in one GK Smoother formula and many other brands. Relaxers provide slightly longer results such as 5 to 12 months, but contain Sodium Hydroxide.
It is a "controlled melt" of the stands which relaxes the bonds temporarily providing easier to manage hair, but at a grave cost. Sodium Hydroxide will no longer be available in the cosmetics industry in 2025 due to consumer safety issues. It is the same chemical used in grill and oven cleaners, as well as pipe cleaners that remove hair clogs.
In summation, there are a lot of "New" products on the market, but they come with health problems. I am not comfortable with any brand that knowingly markets dangerous products to the public, as well as professionals who would be exposed repeatedly.

Yes. However, all bleach and harsh lighteners should be done after the Japanese straightening.
Hair that has been lightened too many levels is too difficult to straighten economically or safely, at times. Hair can easily be highlighted afterwards because your colorist can control where they apply lightener and goes on visual cues.
I cannot control the varieties of solution strengths, application timing, and strands so easily. Additionally. It is impossible for me to know if any bleach mistakes were covered with toner or color. such areas will immediately begin degrading and an emergency rinse is necessary at that moment to prevent damage.
Appointments are required for all services.
We offer Japanese Permanent Straightening, haircuts, coloring, highlights, balayage, and more.
Japanese is not safe for previously bleached hair as it is not possible to determine if any over-bleaching has been covered with color or toning. Especially on naturally dark hair.
Yes! However, it is recommended that you opt for Balayage which means "hand painted" in French. this allows for keeping bleach away from your roots or new growth which can challenge successful Japanese Straightening touch-ups. Balayage also requires less trips to the salon, so maintenance is easier and costs less.
No! Shampoo selection is very personal due to other hair and scalp care needs, including budgets and convenience. We will teach you how to select the safest shampoo for your home hair care maintenance. We will discuss your priorities and steer you in the right direction.
Yes. Salon applied color is always safe prior to or after Japanese Straightening. Root color touch-ups are best after your straightening because teh treatment can lighten your hair half a level. The new level is beautiful and can never be achieved otherwise. Most all my clients opt to match the new half level lighter shade. We don't want slightly darker roots since I cannot apply the straightening solution close to the scalp.
I no longer straighten hair that's been colored at home due to high risk of overprocessed hair. Clients aren't skilled at proper application of color. The solution will cause the over processed strands or areas to glow a bright yellow which indicates degradation of hair (due to over processed hair). Emergency rinse is necessary.
