Science
Mechanism of Action
This ingredient utilizes Bacillus subtilis fermentation to cleave soy proteins into low-molecular-weight peptides while converting biotin into a more soluble, bioactive form. It targets the dermal papilla cells to accelerate keratin synthesis and provides anti-inflammatory support to the scalp environment, effectively anchoring hair roots and soothing irritation.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 In vivo testing at 3% concentration demonstrated a 12% improvement in hair density alongside measurable reductions in scalp redness.
- 02 Clinical evaluations confirm significant enhancements in hair shaft structural integrity and keratinization levels with consistent application.
Transparency
Dusting Analysis
Often listed in trace amounts for 'label claims' regarding biotin; however, clinical hair density benefits require a minimum threshold of 1.0%, with 3.0% being the benchmark for therapeutic results.
The Formula
Formulation
Stability
Highly stable in aqueous, slightly acidic environments; Polysorbate 80 acts as a built-in stabilizer to maintain biotin solubility within the filtrate.
Synergies
- Scalp antioxidants
- Caffeine
- Zinc PCA
Conflicts
- Strong oxidizing agents
- Highly alkaline formulations (pH > 8.0)
Safety
Safety Profile
Biotin is a non-toxic, water-soluble vitamin. The fermentation process yields a gentle profile suitable for compromised scalp barriers.
