Q&A

I'm summarizing frequently asked questions from customers about K.fix.

What are the benefits of using "K.fix" in a nutshell?

It's about time-saving and repair. Perm and treatment can be done simultaneously in a short time, reducing the burden on customers and enhancing satisfaction.

Why can it repair?

It's possible through simultaneous treatment of perm and treatment, such as liquid crystal treatment base formulation and strength recovery through cross-linking.

What's easy about it?

With a 5-minute setting for leaving the first agent, it allows for automatic work in a short time.

What's the difference from cold perm?

It activates the effective ingredients of the perm through heating. It doesn't take effect with natural setting.

What is the paradigm shift in heat? Does heat not cause pain?

We leverage the heat used for perms to simultaneously benefit the treatment, efficiently turning heat into an advantage.

How is it different from regular hot perms?

The first agent is formulated to be in liquid crystal form, allowing for simultaneous treatment and reduction, resulting in a shorter processing time and enabling over 90% strength recovery through combined use with processing agents.

How much time difference is there compared to traditional hot perms?

With reduced processing time and improved operability, treatments can be completed within 2 hours.

Is the KAIZEN course an acid heat treatment?

No, it's not. It utilizes glyoxylic acid and maleic acid to balance protein, CMC, and moisture, resulting in less acidity and odor, and also considers preventing color fading.

How does it differ from acid heat treatments?

While it uses glyoxylic acid and maleic acid like typical acid heat treatments, it emphasizes a softer treatment effect by using a milder acidity level.

What's the timing for the KAIZEN course?

Approximately once a month. We recommend it after "K.fix perms", cuts, or other treatments to maintain healthy hair.

How many times should one undergo the KAIZEN course?

We recommend experiencing the KAIZEN course every month. Depending on hair length and damage level, you may feel the effects even after just three sessions.

Is it okay not to use heat for the KAIZEN course?

Heating is recommended. While some effects can be achieved without heat, it's best to apply heat for optimal effectiveness.

What's the main ingredient in "K.fix platinum"?

Elaplex, urea, γ-docosanol, hydrolyzed silk, ceramide-like ingredients, amino care ingredients, macadamia nut oil, jojoba oil.

Why is Elaplex included in "K.fix platinum"?

It strengthens the hair by forming cross-linking bonds, has good compatibility with color treatments, and can be used at any stage.

What's the difference between "K.fix direct" and "K.fix bridge"?

"K.fix direct" promotes penetration of the first agent or treatment, while "K.fix bridge" protects, repairs, and strengthens damaged areas.

What's the purpose of "K.fix direct"?

It's a processing agent for promoting penetration with the aquasome and ensuring uniform agent action.

What's the purpose of "K.fix bridge"?

Its main function is to restore strength through cross-linking bonds.

How is "K.fix direct" different from pre-treatment by other companies?

It enhances penetration. With microcapsule technology, it efficiently repairs hair in a short time and reduces uneven agent reactions.

Why use "K.fix bridge"?

It forms cross-linking bonds to strengthen the hair and improve its health.

Is "K.fix bridge"・"K.fix platinum" effective at room temperature?

Heating is recommended. It uses a formula that exhibits bridging effects through heat.

Which is better for "K.fix bridge"・"K.fix platinum", dry heat or moist heat?

Both are fine. Both methods effectively perform treatment and cross-linking bonds through heat.

Can "K.fix bridge" be used before ironing?

Yes, it can. It efficiently forms cross-linking bonds.

Is "K.fix direct" alone sufficient for highly damaged hair?

"K.fix direct" alone is not sufficient. "K.fix direct" is a penetration enhancer. Apply "K.fix bridge" on highly damaged areas as well.

Why is there over 90% hair strength recovery?

It's based on the results of measuring hair tensile strength after treatment. Our tests have shown over 93% strength recovery.

Is it okay to start from dry hair?

It's not recommended. Please moisten the hair with a sprayer before applying the agents.

Is 'TSUKEDEGI' possible? *TSUKEDEGI" is a technique of perming where the perm solution is not rinsed out, and the hair is permed by winding it around rods.

It's possible. It can be used as a heated perm. Lower the temperature to below 60°C, and keep it for about 5 minutes.

If the first agent is heated, can the processing time be less than 5 minutes?

Heating the first agent is possible since it's a formulation based on the assumption of heating, but do not heat after application.

What are the benefits of the first agent?

The benefit is that it allows simultaneous treatment and reduction by liquidizing it, providing a good touch when rinsing, and improving operability afterward.

What is the main component of 90% treatment agent?

The ratio of protein, oil (CMC), and moisture liquidized into a treatment agent.

"K.fix yellow" and "K.fix red" can't be used for hair straightening?

You can use them. Adjust the iron temperature lower according to the level of damage.

Why can the first agent react in 5 minutes?

It's possible due to the action of "K.fix direct" (penetration enhancer) and the liquid crystal emulsification formulation of the first agent.

Is the processing time 5 minutes regardless of the damage level?

It's achievable with proper selection of agents.

Is overtime okay regardless of the damage level?

The first agent contains dithiodiglycolic acid, which has a buffering effect, so it works regardless of the damage level.

Do you need to apply quickly because it softens in 5 minutes?

The application time is assumed to be within 10 minutes. While standard application methods are sufficient, the formula's good spreadability allows for quick application with combing, etc.

What if it's left on for more than 5 minutes?

While there's minimal risk due to the inclusion of dithiodiglycolic acid, please strictly adhere to the precautions for use as a quasi-drug.

Is it okay to leave only the first agent for 5 minutes? (Is 5 minutes okay without "K.fix direct"?)

Using "K.fix direct" allows for a 5-minute processing time.

Can you check if it's softened?

It becomes clearer by wrapping a test rod after applying the agents.

What is liquid crystal emulsification?

It refers to very fine emulsified particles (liquid crystals). By balancing proteins, CMC (oil), and moisture, it improves the spread and penetration of the agents.

How do you select agents based on the damage level?

DLv.0~1:K.fix black,DLv.2:K.fix red,DLv.3:K.fix yellow,DLv.4:K.fix white Those are references.

How to distinguish damage levels

Refer to the damage level table below:

K.fix Damage Chart
Level 0 Level 1 Level 2 Level 3 Level 4 Level 5
Hair Condition Healthy Floats begin to appear at the tips of the cuticles, but the outflow of interstitial substance is minimal. Damage starts to appear on the cuticles, with cracks and small chips at the tips, and the outflow of interstitial substance begins. There are many chipped areas at the tips of the cuticles, and interstitial substance is partially flowing out. The missing areas of the cuticles become larger, and the outflow of interstitial substance is intense, partially leading to cavitation. The cuticles are significantly damaged, with interstitial substance flowing out and cavitation occurring.
Visual and Tactile Inspection Shiny, moisturized, with weight and elasticity, and water repellent. Slightly less shine, Still with weight and elasticity. Slightly less shine, starting to dry, with elasticity. No tangling when wet. Severely dry, with surface roughness, loss of shine, and beginning loss of elasticity. Tangling occurs when wet. Dry, lacking shine and elasticity, light. Gritty when dry. Stretched when wet. May appear whitish or translucent. Breakage occurs when pulled dry, It knots tightly when wet.
Treatment History Non-coloring, non-perming, no environmental damage from UV rays or dryness.
Not using of hairdryers and irons.
Using a hairdryer or iron. There is environmental damage such as UV rays and dryness. No chemical history. Regular overlap with low to medium brightness colors. Overlap with perms. Regular overlap with low to medium brightness colors. Overlap with perms. Regular overlap with medium to high brightness colors. Overlap with perms, straightening treatments. Frequent or prolonged overlap with bleach or high brightness colors. Overlap with perms, straightening treatments.

Is it okay to use "K.fix GMT" on wet hair?

We recommend performing the treatment on wet hair. Moisture helps the penetration of the reducing agent. Ideally, the hair should be towel-dried after shampooing.

What pre-treatment is recommended when using "K.fix GMT"?

For healthy hair, use "K.fix direct". For damaged hair, use "K.fix bridge".

What are the benefits of "K.fix GMT" being in its original form?

It's easier to calculate, and since both the agent and "K.fix GMT" are not diluted, you can expect the penetration and treatment effects of "K.fix" directly.

Why does "K.fix GMT" react in 5 minutes?

By formulating "K.fix GMT" in its original concentration without dilution and incorporating liquid crystal emulsification into the base, a reaction time of 5 minutes is achievable.

What types of hair can be straightened or curled in 5 minutes with "K.fix GMT"?

While there may be exceptions depending on hair texture and condition, the treatment can generally be done in 5 minutes.

How do you perform the reduction check?

After applying Agent 1, wrap fine rods, aiming for a diameter 1.5 to 2.0 times the rod size, for the check. Due to the high penetration power of the liquid crystal emulsification formula, a check can be done in 5 minutes.

What are the temperatures for hair straightening and hot perms?

For hair straightening: 160°C–180°C for quick ironing through (140°C–160°C for damaged areas). For hot perms: 70°C–80°C for about 7 minutes.

Why is "K.fix platinum" necessary when mixing "K.fix GMT"? Can other brand treatments be used?

"K.fix platinum" treatment has unique properties and penetration power that other products do not have. ※We have not conducted verification with other brand products, so please do not mix.

Does "K.fix GMT" act on S-1 or S-2?

It acts on S-2.

Why is acidic straightening popular? Why did "K.fix" make it possible?

With the popularity of high tones and increasing complexity of damage, we have made it possible to propose acidic treatments with the "K.fix" series, which were previously challenging to recommend.
