DEMI Hair & Scalp Science: Research Behind Professional Care
Professional hair care involves much more than choosing products by hair type. Salon professionals work with different levels of damage, scalp conditions, chemical service histories, desired textures, and individual client needs.
For DEMI COSMETICS, understanding these differences begins with research. Hair and scalp science have been central to DEMI's professional product development for decades, reflecting DEMI's philosophy that beauty evolves through science.
Behind this approach is the DEMI Hair Science Laboratory, established in 1984 to study hair, scalp, ingredients, formulations, and the technologies used to evaluate them.
From Textile Chemistry to Hair Science
DEMI's scientific approach has roots beyond the beauty industry. As the professional cosmetics business of Japanese chemical manufacturer NICCA CHEMICAL, DEMI developed from a company with long-standing expertise in textile and wool processing.
Technical knowledge related to washing, improving smoothness, and dyeing provided a foundation that could later be applied to professional hair cosmetics, including shampoos, treatments, perm products, and hair colour.
This background in chemistry and materials science helped shape an approach in which hair is not simply treated cosmetically, but observed, measured, analysed, and used as the basis for product development.
Inside the DEMI Hair Science Laboratory
Since its establishment in 1984, the DEMI Hair Science Laboratory has accumulated around four decades of specialised research into hair and scalp.
The laboratory investigates hair and scalp conditions from multiple perspectives. Its work includes hair science, skin and scalp science, analysis and evaluation, investigation of functional ingredients, and formulation development.
DEMI also uses analytical and measurement equipment for work such as physical property measurement, cell culture, and genetic analysis, helping researchers examine hair and scalp conditions and explore new ingredients and technologies.
The research process can be understood in a practical way:
- Observe and analyse hair or scalp conditions
- Investigate possible causes, materials, and functional ingredients
- Measure and evaluate potential technologies
- Translate research findings into formulations and professional products
DEMI's work also extends beyond its own laboratory. The company collaborates with research institutions, universities, and hair professionals, connecting fundamental research with knowledge from the professional salon field.
Connecting Research With Professional Salon Work
For salon professionals, the important point is not simply how much research takes place in a laboratory, but how that knowledge is translated into practical professional care.
DEMI describes a research and development system in which fundamental research and product development are closely linked. Hair and scalp analysis can help identify areas to investigate, while formulation and evaluation work help turn those findings into products that can be used in professional services and ongoing care.
This connection can be seen particularly clearly in several DEMI ranges, each showing a different way in which hair or scalp research is applied.
Scalp Science in Practice — DEMI DO
DEMI DO is one of the clearest examples of DEMI's long-term scalp and hair research being translated into a contemporary professional care range.
Developed after decades of research, DEMI DO approaches the scalp and hair together, reflecting the idea that ongoing scalp care forms an important part of maintaining healthy-looking hair.
Two examples of this research-led development are ROOT ACTIVE and KEEP ACTIVE. ROOT ACTIVE was discovered through four years of fundamental research, including joint research with a leading research institution in Japan, while KEEP ACTIVE was developed by the DEMI Hair Science Laboratory. Together, they provide a concrete example of how DEMI translates scalp research into cosmetic product formulation.
Rather than positioning scalp care only around specific concerns, DEMI DO also presents it as part of a regular care routine. This gives salon professionals a research-led care concept that can be incorporated into salon services and home care recommendations.
Hair Science in Practice — FLOWDIA
While DEMI DO demonstrates the company's approach to scalp science, FLOWDIA shows how DEMI applies research to damaged hair.
FLOWDIA focuses on understanding the physical condition of hair that has accumulated damage and translating those findings into targeted repair technologies.
Balneid System — Selective Damage Repair
One of FLOWDIA's core technologies is the Balneid System. DEMI describes this as a selective repair approach that responds specifically to damaged cavities within the hair, forming care balloons that encapsulate repair components within those areas.
The concept illustrates a research-led approach to hair repair: instead of treating the entire hair fibre in exactly the same way, the technology is designed around where damage exists within the hair structure.
Bonded System — Addressing Disordered Hair Bonds
FLOWDIA also uses the Bonded System, developed around DEMI's study of how accumulated damage can affect bonds within the hair and contribute to changes in its form and manageability.
The system is designed to help loosen and realign these disordered bonds, supporting a more manageable hair condition while maintaining a natural-feeling texture.
Both technologies demonstrate the same underlying idea: study the physical changes occurring in damaged hair first, then develop a care approach around those findings.
Extending Hair Repair Research — FLOWDIA MORE
FLOWDIA MORE extends this approach to hair with more complex or accumulated damage histories.
Its professional system treatment combines multiple internal and external repair approaches rather than focusing on a single damage factor. These include technologies derived from FLOWDIA's existing research, such as the Balneid System and Bonded System, alongside additional approaches for internal structure, moisture, keratin care, heat-responsive care, and the hair surface.
For salon professionals, FLOWDIA MORE provides another example of how DEMI develops multi-step professional treatment systems around different aspects of damaged hair structure, rather than treating damage as one uniform condition.

Hair Colour Technology in Practice — TOIROCTION
DEMI's research-led approach also extends to professional hair colour. TOIROCTION combines colour design with formulation technologies developed around the condition of the hair and the colouring process.
One example is waterfowl-derived hydrolysed keratin, which is used to help fill damage holes and create a more even hair base during colouring. TOIROCTION also uses a moisture-holding oil blend and DEMI's Oxy Stabilizer formulation, which controls the decomposition of hydrogen peroxide to support bleaching performance with reduced alkali levels. Together, these approaches show how DEMI applies its knowledge of hair condition and chemical processes to professional colour services.
Science for Professional Salon Treatments — COMPOSIO & COMPOSIO EQ
DEMI's hair science also extends into professional salon treatment and processing support through COMPOSIO and COMPOSIO EQ.
COMPOSIO — Professional Processing Support
COMPOSIO combines hair science with DEMI's proprietary complex fixation technology. It is designed as a professional pre- and post-processing support range, with products developed to work alongside salon chemical services and respond to different aspects of hair damage.
Its formulation concept shows how DEMI applies hair-science principles and fixation technology to products used during professional technical work.
COMPOSIO EQ — Professional System Treatment
COMPOSIO EQ is positioned as a professional salon system treatment. It is designed to repair and care for the hair internally through a multi-step treatment process.
Across the broader COMPOSIO offering, these approaches show how DEMI applies its hair science across different parts of professional salon work — from supporting chemical services to structured treatment care.
Why Hair & Scalp Research Matters for Salon Professionals
Salon professionals work with varied hair and scalp conditions, service histories, and care needs. DEMI's approach connects fundamental research, evaluation technology, formulation development, and professional salon applications, providing a scientific framework for developing products around those different challenges.
DEMI DO, FLOWDIA, FLOWDIA MORE, TOIROCTION, COMPOSIO, and COMPOSIO EQ demonstrate different ways this expertise is applied across scalp care, damage care, professional colour, processing support, and professional salon treatments.
