Silicon, particularly in the form of orthosilicic acid or silicon-rich supplements, has garnered scientific interest for its role in supporting hair health, especially in cases of hair loss or thinning. Silicon is a trace element found in various tissues, including hair, skin, and nails. Its potential benefit arises from its role in collagen synthesis and structural integrity of connective tissues. Several clinical studies have explored silicon supplementation, with some double-blind, placebo-controlled trials indicating that silicon (notably, choline-stabilized orthosilicic acid) can improve hair tensile strength and reduce hair brittleness after several months of use. These studies suggest that silicon may contribute to hair fiber formation and possibly stimulate keratin production, which is crucial for hair growth.

However, the body of evidence is not extensive. A handful of small to medium-sized clinical trials and review articles form the basis for the current scientific consensus, and while results are promising, they are not definitive. No large-scale, long-term studies have established silicon as a primary treatment for hair loss, but its supplementation is considered safe when used as directed. Because of this, silicon is often included in "hair, skin, and nails" supplements, and its use is rooted in emerging scientific validation rather than tradition. More robust research is needed to fully clarify its efficacy and optimal dosing for hair-related conditions.
