Sea Kelp is a brown-green coloured alga that has been consumed in Asia for centuries. More recently it has become increasing popular in the West. Sea Kelp is believed to be beneficial for hair growth, however, this claim is more likely attributed to the range of vitamins and minerals that are found in this plant. These Vitamins include A, B1, B2, C, D and E as well as minerals such as zinc, magnesium, iron, copper, potassium and calcium.
Sea Kelp is particularly high in the mineral iodine, which can help to maintain normal thyroid function. Iodine deficiency can cause conditions like hypothyroidism, which can lead to hair loss and thinning. Therefore, upon the consumption of iodine rich foods like Sea Kelp, it may appear to be attributing to hair growth, whereas it is helping to treat hypothyroidism, the original cause for the hair loss.However, that is not to say Sea Kelp does not have its benefits as it does contains vitamins and minerals that can promote hair growth and improve the overall look and condition of your hair (e.g. Vitamin A, E, zinc and iron). For example, iron deficiency can cause anaemia, which can result in thinning hair. Therefore, Sea Kelp may help improve this condition and promote hair growth.
