Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Sulfur compounds are scientifically recognized for their role in supporting hair health, primarily because sulfur is an essential component of keratin, the main protein in hair. The most notable sulfur-containing compound relevant to hair is methionine, an amino acid, as well as cysteine, both of which are building blocks for keratin. Historically, sulfur has also been used in topical hair treatments for its antimicrobial and antifungal properties, which can help address scalp conditions that may impede healthy hair growth.
Recent scientific studies suggest that supplementation with sulfur-containing amino acids may help in cases of hair fragility, thinning, or loss, especially when these issues are due to dietary deficiencies. For example, methylsulfonylmethane (MSM) is a popular dietary supplement that provides bioavailable sulfur and has been investigated for its effects on hair growth and strength, with some small studies and anecdotal reports suggesting benefits, although large-scale, high-quality clinical trials are limited.
Overall, the use of sulfur compounds to support hair health is grounded in both biochemistry and limited clinical data, with most evidence supporting their use as part of a balanced diet rather than as standalone hair growth cures. More research is needed to fully characterize their effectiveness, but there is a scientifically plausible basis for their role in maintaining hair structure and health.
