The Next-Gen Straightening Iron That Doesn't "Strip" Moisture
— A Thorough Review of the SPASYS DBST (DBST-24)
Don't let it evaporate. Lock it in. — A new standard for heat, proposed by KEMA JAPAN.
Why does your hair seem to get drier the more you use a flat iron every morning? This discomfort, felt by many, actually stems from the very structure of the iron itself. The SPASYS DBST (commonly known as the DBST-24) introduced here is a next-generation straightening iron that fundamentally overturns this "conventional wisdom." Its greatest feature is the use of patented silicone plates, designed not to strip moisture from your hair, but rather to "lock it in."
01What exactly is the DBST-24?
The SPASYS DBST is a new-generation professional straightening iron for salons, developed by the hair care brand KEMA JAPAN (bc.art Co., Ltd.). The name "DBST" stands for Dual Bonding Silicone Technology, referring to its proprietary, patent-pending silicone plate technology.
While most common hair irons use metal plates like ceramic or titanium, the DBST stands out for its deliberate use of silicone plates. These plates have such high moisture-retention properties that if you drop water onto them, the droplet remains rounded without evaporating.
02Why do standard irons damage hair?
To understand the brilliance of the DBST-24, it helps to first understand the mechanism behind how conventional irons damage hair.
Typical metal-plate irons are effective at transferring intense heat instantly. However, this causes the moisture inside the hair shaft to vaporize all at once, bursting through the cuticle from the inside out—a phenomenon known as a "steam explosion."
When a steam explosion occurs, the proteins that make up the hair also undergo "thermal denaturation." This is the same process as an egg hardening when cooked. Unfortunately, once proteins are denatured, they cannot be restored. Through daily ironing, these small damages accumulate, eventually resulting in dryness, breakage, and loss of shine.
03The Core Technology of the DBST-24: Patented Silicone Plates
The DBST-24’s silicone plates are designed to transfer heat not "intensely and quickly," but "gently and uniformly." This redesign of heat conduction at the material level is its greatest breakthrough.
The moisture-retaining nature of the plate surface allows you to style your hair while keeping internal moisture intact, rather than forcing it to vaporize rapidly. Additionally, the unique cushioning effect of the silicone prevents the hair shaft from being "crushed."
According to data provided by the manufacturer, the risk of protein thermal denaturation is reduced by approximately 80–90% compared to conventional straightening irons. It is designed to minimize the burden on your hair, even with daily styling.
04The Definitive Differences: 4 Revolutionary Points
Patented Silicone Plates
Mild heat conduction that doesn't damage the cuticle. Does not exert the heavy pressure on hair typical of metal plates.
Prevents Steam Explosions
Protects moisture within the hair and styles it while locking in hydration. Eliminates the root cause of dryness.
Significantly Reduced Denaturation Risk
Thoroughly inhibits protein denaturation. Designed so that elasticity and shine are maintained even with daily use.
Doesn't "Crush" Hair
Keeps the cross-section of the hair round for a soft, natural finish. Maintains volume instead of flattening the hair.

07"Proper Usage" with KEMA Hair Care
The true value of the DBST-24 is maximized when used in combination with KEMA hair care products. Since this iron "locks in moisture," it is crucial to consider what nutrients you apply before locking them in.
-
Towel-Dry Preparation
After shampooing, lightly towel-dry. Excessive water reduces thermal efficiency, so a light squeeze is sufficient.
-
Apply KEMA Balm
Work MIRACLE BOND BALM or LEAVE-IN BALM into the mid-to-ends of the hair. This delivers proteins and amino acids while creating a protective layer.
-
Dry Thoroughly
Dry completely from roots to ends. The DBST-24 should never be used on wet hair. Always use it in a dry state.
-
Style with DBST-24
Set to a temperature appropriate for your hair type and slide carefully. This locks in moisture and nutrients while shaping the hair.
-
Finish with KEMA Oil
Apply a small amount of PENTA S OIL to the mid-to-ends for a coating of shine to finish.
08Recommended For
- Those struggling with dryness and damage from daily ironing
- Those who feel their hair has weakened from repeated bleaching or coloring
- Those who dislike the "straight but stiff" finish of traditional chemical straightening
- Those noticing a loss of hair bounce and shine as they age
- Frequent travelers who want to use the same iron worldwide
09Care and Maintenance
Because the silicone plates are made of special materials, gentle maintenance is the secret to longevity.
- Check the condition of the cord and plates before use
- Do not use on wet hair (always dry first)
- Do not apply heat to the same section for prolonged periods
- After use, wait for the unit to cool completely before wiping with a soft, dry cloth
- Do not use abrasive cleaners or hard brushes
- Store away from high heat, humidity, and direct sunlight
10Summary: A New Choice to "Style While Protecting"
The DBST-24 (SPASYS DBST) is a device that shifts the criteria for choosing an iron from "how fast it heats up" or "price" to "how effectively it can protect the hair." The idea that maintaining long-term hair health is more cost-effective than choosing a cheap iron might become the new standard.
Moving from irons that "only straighten" to ones that "style while locking in hydration"—if you are someone who wants to choose a product that truly benefits your hair, the DBST-24 is well worth your consideration.
