Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Marine protein is used to support hair health primarily due to its content of bioactive peptides, amino acids, and sometimes collagen derived from marine sources such as fish. Several scientific studies have investigated oral supplementation with marine-derived proteins, hydrolyzed collagen, and related compounds for their effects on hair growth, strength, and appearance. While some small clinical trials and pilot studies suggest that marine protein supplements may improve hair density, reduce hair shedding, and enhance hair thickness—especially in women with thinning hair—the overall quality of evidence is moderate and not yet definitive. Most studies focus on multi-ingredient formulations (e.g., Viviscal), which include marine protein along with other nutrients like biotin and vitamin C, making it difficult to attribute effects solely to marine protein.

The hypothesized mechanisms involve providing essential amino acids for keratin synthesis and delivering specific peptides that may stimulate hair follicle activity. However, larger, independent, and longer-term studies are needed to confirm these findings. Marine protein is not traditionally used in herbal medicine for hair health, but its scientific basis is growing, albeit modestly. Therefore, while there is some scientific support for the use of marine protein in hair health supplements, the evidence is limited and not universally accepted in the medical community.
