Silica Supplementation and Hair Tensile Strength

Clinical Evidence

• Clinical studies investigating orthosilicic acid and other bioavailable forms of silica have demonstrated measurable improvements in the structural integrity and tensile strength of hair.
• Research involving female subjects with fine or thinning hair showed that supplementation with stabilized choline-stabilized orthosilicic acid led to a statistically significant decrease in hair brittleness and an increase in hair elasticity and break resistance.

Mechanism of Action

• Silicon is an essential trace element concentrated in connective tissues, including keratin-rich structures like hair and nails.
• It acts to optimize the synthesis of collagen and enhance keratin deposition, which directly contributes to the physical resilience, thickness, and overall tensile strength of the hair shaft.

Nutritional Considerations

• Dietary intake of silicon from plant-based foods is often poor due to low bioavailability.
• Standardized supplemental forms are generally required to achieve plasma concentrations high enough to stimulate the fibroblasts responsible for structural protein formation in hair follicles.
