Salmon is a popular food. It’s also considered by many hair experts to be the perfect hair food. Why? Classified as an oily fish, salmon is considered to be hair healthy due to the fish’s high protein, high omega-3 fatty acids, and high vitamin D content. All of these ingredients are key for healthy scalps and strands.
Salmon is also a source of cholesterol, with a range of 23–214 mg/100 g depending on the species. According to reports in the journal Science, however, farmed salmon may contain high levels of dioxins. PCB (polychlorinated biphenyl) levels may be up to eight times higher in farmed salmon than in wild salmon, but still well below levels considered dangerous.
The human body can’t produce fatty acids, which are required to grow healthy hair. In fact, Omega-3s are part of the cell membranes in the skin of the scalp. The natural Omega-3 oils help produce necessary hydration for the scalp and tresses. About 3% of the hair shaft is make up of these fatty acid.
