Cod liver oil for hair

Updated April 17, 2017

Just like the rest of your body, hair needs proper nourishment to look and feel its best. Consuming cod liver oil supplements is widely accepted as a good method of boosting hair's radiance, according to tests done by Channing Laboratory in Boston. This is because cod liver oil is rich in omega-3 fatty acids, which stimulate cell reproduction.

Omega-3 Fatty Acids

Of all the components in cod liver oil, omega-3 fatty acids are generally the main attraction for those who take the supplement. As well as promoting circulatory health, omega-3 fatty acids are known to boost the nutrition of hair from follicle to tip, resulting in shinier, smoother hair. Furthermore, those who consume high amounts of omega-3 fatty acids are less likely to experience hair loss. This is because omega-3 acids are known to stimulate the hair follicles, resulting in both faster-growing hair and hair more resistant to loss.

Cod Liver Oil and Hair Nourishment

Hair's health is directly connected to personal health. However, even if you maintain a healthy diet, hair can sometimes appear lacklustre and dry. omega-3 fatty acids eliminate dry, brittle properties in hair by distributing vitamins down the shaft of the hair. This helps to promote strength in hair, although it can take time for the benefits to show. Vitamin boosts build up slowly and remain in the body for a long time, as the vitamins in cod liver oil are fat-soluble, stored in the body's fat cells for years.

Other Components of Cod Liver Oil

Though omega-3 fatty acids are the most concentrated and sought-after components of cod liver oil, the substance also contains high amounts of vitamins A and D. These two vitamins are known to benefit the body's function and appearance. Vitamin A, in regulated amounts, also works to improve the appearance and strength of skin and hair as well as improve eyesight. Meanwhile, vitamin D works to strengthen bones, teeth, and cartilage while regulating blood calcium levels.

Risks of Taking Cod Liver Oil

However, cod liver oil is not for everyone. Those who suffer from fish allergies should not take cod liver oil. (Though plant-based sources of omega-3, such as soybeans and flax, exist, they do not contain the high concentrations of the fatty acids that cod liver oil does.) Furthermore, women who are pregnant should ask their doctor before taking cod liver oil, as the high concentrations of vitamin A can cause fetal birth defects. Children should not take cod liver oil without the approval of their paediatrician.
