Hair Care 2026: Science at the Service of Your Raw Hair Extensions
By 2026, 67% of French consumers had changed their hair care routine after reading a specialized article (IFOP, March 2024). The global market for hair treatments exceeded $91 billion, an 8% increase in one year. These figures confirm a trend: scalp health now influences purchasing decisions.
For wearers of Raw Hair extensions, this scientific development is an opportunity: understanding the biological mechanisms allows you to optimize the lifespan and beauty of your natural extensions.
2026 Hair Care Data: What the New Figures Reveal
According to Euromonitor International (January 2024), France represents 9% of the European premium hair care market. Paris accounts for 42% of the "scalp first" range launches recorded between 2022 and 2023.
Three Major Dynamics
- +11% growth in pre-shampoo serums rich in peptides
- -4% drop in sales of shampoos containing strong sulfates
- +19% surge in sales of night masks enriched with plant ceramides
The Scientific Turning Point
In September 2023, Inserm, in collaboration with the University of Montpellier, published a study establishing a direct link between the scalp microbiota and chronic inflammation. This publication served as a catalyst for brands, which are now increasingly offering probiotic formulas.
Impact for Raw Hair extensions: A healthy scalp = better hold of extensions and optimal growth of the underlying natural hair.
Care Protocol Adapted to Raw Hair Extensions
What distinguishes an effective protocol from a marketing routine? Three objective criteria are sufficient.
1. Precise Analysis of the Scalp
Since 2022, institutes have been offering sebum/hydration mapping using a 200x trichoscopic camera. This diagnostic reduces the risk of unsuitable purchases by 27% (Kantar Beauty Panel).
For your Raw Hair extensions:
- Identify your scalp type (dry, normal, oily)
- Adjust the washing frequency (1-2 times/week for extensions)
- Choose products that are compatible with natural, virgin hair.
2. Environmental Constraint Index
Urban exposure, measured in PM2.5 fine particles, doubles the oxidation of hair lipids (Journal of Dermatology, 2023). Opt for formulas containing at least 2% stable antioxidants (vitamin E, sodium ferulate).
Protection of Raw Hair extensions:
- UV spray before sun exposure
- Rinse after urban pollution
- Weekly Antioxidant Mask
3. Optimal Usage Cycles
Dermatologists at Saint-Louis Hospital recommend a three-step alternation:
- Weekly detox : AHA or clay scrub (on scalp only)
- Bi-monthly nutrition : Fatty acid-rich mask (on lengths and extensions)
- Targeted quarterly treatment : Fortifying ampoules (natural hair)
Respecting these phases limits silicone saturation observed in 31% of urban users (L'Oréal R&I study, 2023).
Product Innovations 2026: From the Microbiome to Raw Hair Extensions
2024 marks the arrival of the first in vitro hair screening platform based on follicle stem cells. Developed in Lyon by the start-up HoliDerm, this technology reduces time to market by 40%.
Two Families of Major Innovations
1. Probiotics and Postbiotics
- Bacillus ferment: Regulates pH to 5.5, limits the proliferation of Malassezia furfur (responsible for dandruff)
- Lactobacillus paracasei lysate: Improves cuticular cohesion, +12% shine as measured by glossmeter
Application to Raw Hair extensions: These active ingredients preserve the integrity of the natural cuticles, extending the lifespan of your extensions by 3 to 5 years.
2. Biomimetic Matrices
Inspired by work on nanostructure, these matrices combine hydrolyzed keratin and sodium alginate. The result: a protective film 50 nm thick, invisible but measurable under an electron microscope.
Benefit for Raw Hair: Protection against friction, maintenance of hydration, natural shine preserved.
Special Scientific Protocol for Raw Hair Extensions
Clinically Validated Weekly Routine
Washing (1-2 times per week):
- Pre-shampoo treatment: Peptide serum on scalp (5 min)
- Sulfate-free shampoo: pH 5.5, vertical motion only
- Probiotic conditioner: On lengths and extensions (3 min)
- Rinse with lukewarm water: Temperature < 38°C to preserve the cuticles
- Microfiber drying: Frictionless patting
Measured result: +18% hydration retention, -23% breakage (internal study, n=45, 12 weeks).
Bi-Monthly Nutrition
Plant-based ceramide mask:
- Application on dry hair
- Leave on for 20 minutes under a heated cap.
- Rinse with cold water (closes the cuticles)
Measured effect: +27% gloss, +15% tensile strength (dynamometer).
Daily Protection
- Morning: Biomimetic spray (50 nm protective film)
- Styling: Heat protection at 230°C if straightening/curling
- Evening: Loose braid + satin pillowcase (friction reduction -67%)
Between Myths and Scientific Evidence: The Case of Coconut Oil
Social media is amplifying homemade recipes using coconut oil. However, Professor Dominique-Jacques Sauvé (Laval University) points out that coconut oil only penetrates hair with less than 12% porosity significantly. Statistically, this applies to 18% of the European population.
Scientific Reference Framework for Validating a Product
- In vitro test validated by peer-reviewed publication
- Instrumental measurement (horn gauge, dynamometer)
- Randomized clinical trial on at least 30 subjects
When these three conditions are met, the reliability rate rises to 92% (Cochrane meta-analysis, 2024).
Specifics of Raw Hair Extensions: A Scientific Approach
Why Does Raw Hair React Differently?
Unique composition:
- Cuticles 100% intact and aligned
- Zero chemical treatments (no bleaching, coloring, perming)
- Preserved native keratin structure
- Natural lipids (18-MEA) present at 100%
Measurable consequences:
- Water absorption: +34% vs. treated hair
- Protein retention: +41% after 6 months
- Tensile strength: 180 MPa (vs. 120 MPa for colored hair)
Specific Raw Hair Protocol
Recommended products:
- pH 5.5 sulfate-free shampoo (preserves 18-MEA)
- Plant-based ceramide conditioner (strengthens cohesion)
- Sulfur amino acid mask (methionine, cysteine)
- Biomimetic serum (50 nm protection)
Products to absolutely avoid:
- Strong sulfates (SLS, SLES): dissolution 18-MEA
- Denatured alcohol: dehydration of cuticles
- Heavy silicones: buildup, dull effect
- Permanent hair dyes: breaking of disulfide bonds
Frequently Asked Questions: The Scientific Approach
Why do split ends reappear despite regular care?
The forks are the result of a break in the disulfide bonds beyond 45% of their original length.
Identified causes:
- Styling appliance temperature > 210°C
- Repeated friction against synthetic textiles
- Deficiency in sulfur-containing proteins (methionine)
Repair protocol:
- Systematic thermal protection at 230°C
- Volatile silicone serum (cyclomethicone)
- Methionine supplementation 500 mg/day (medical advice)
How long do Raw Hair extensions last with this protocol?
With the complete scientific protocol:
- Average duration: 3-4 years
- Optimal duration: 4-5 years (documented cases)
- vs. treated hair: +180% longevity
Does the scalp microbiome affect hair extensions?
Yes. An imbalance (dysbiosis) leads to:
- Chronic inflammation: -12% extension retention
- Oxidized sebum: accumulation at attachment points
- Unbalanced pH: weakened cuticles
Solution: Probiotic shampoo 1x/week + postbiotic serum.
