- Evidence is insufficient. Methylsulfonylmethane is an organosulfur compound and sulfur is genuinely required for keratin, the structural protein of hair, through the disulfide bonds between cysteine residues that give hair its strength - which is the entire basis for the claim. But no adequately controlled trial has tested MSM alone for hair thickness, density or growth. The available human data come from small studies of multi-ingredient supplements containing MSM alongside biotin, collagen, zinc and other compounds, from which no attribution to MSM is possible. Dietary sulfur deficiency is also extremely rare in people eating adequate protein, since methionine and cysteine supply it, so the deficiency-correction rationale does not apply to most people.
