Sanviau Hair Building Fibers
Sanviau Hair Building Fibers are crafted from 100% natural keratin protein to provide instantly fuller-looking hair for both men and women. Designed for all-day durability, these fibers use an electrostatic charge to bond seamlessly to existing hair, staying in place through wind, rain, and sweat.
They effectively conceal hair loss, thinning areas, and signs of alopecia while remaining safe for sensitive scalps. For an enhanced, long-lasting hold, use with Sanviau Fiber Holding Spray. Our formula is free from ammonia, peroxide, synthetic dyes, fillers, and harsh preservatives, ensuring a natural finish that matches your hair perfectly
SANVIAU™ Hair Building Fibers
Cosmetic Density Enhancement
27.5g | Black | Unisex
Precision Cosmetic Camouflage for Thinning Hair
Hair density influences facial balance, perceived age, and professional presence.
Sanviau™ Hair Building Fibers are formulated to deliver immediate visual density correction using refined keratin microfibers that integrate seamlessly with existing hair strands.
This is not a treatment. It is a precision cosmetic solution — designed with clinical discipline and aesthetic restraint.
The Science Behind Sanviau™ Hair Building Fibers
Human hair is composed primarily of keratin protein.
Sanviau™ Hair Building Fibers are crafted from purified keratin, allowing them to:
- Attach naturally to existing hair via static micro-adhesion
- Increase apparent strand diameter
- Reduce scalp contrast
- Enhance density without stiffness
The result is subtle, believable thickness — not artificial coverage.
Formulated With Restraint
We understand, what you exclude matters.
Sanviau™ Hair Building Fibers is formulated without:
- Cotton-based fillers
- Ammonium chloride
- Silica dusting agents
- Chemical binders
- Preservatives
- Parabens
Only:
- Refined keratin protein
- Cosmetic-grade safe pigments
No unnecessary additives. No bulk fillers.
Our Fibers are developed with three priorities:
- Scalp compatibility
- Natural aesthetic integration
- Predictable performance in real environments
- The fibers are lightweight, breathable, and designed to sit on existing strands — not occlude the scalp.
- Removes easily with shampoo.
- Suitable for routine use.
Designed for Early to Moderate Thinning
Our Fibers perform optimally when there is sufficient existing hair for fiber attachment.
Recommended for:
- Diffuse thinning
- Crown visibility
- Part-line widening
- Early hairline recession
- Post-transplant density refinement (when medically cleared)
- Beard density enhancement
Performance Characteristics
- Immediate visible density improvement
- Matte, non-reflective finish
- Transfer-resistant under normal conditions

The finish is subtle. The transformation is refined.
Application Protocol
For optimal results:
- Begin with clean, fully dry hair.
- Apply fibers gradually over thinning regions.
- Lightly pat to distribute.
- Style minimally.
