Seaweed & Kelp For Hair Loss

Hair loss can occur for many reasons, one of which is a nutrient deficiency. Seaweed and kelp contain many vitamins and minerals essential for hair growth, and if you are deficient in any of these, eating seaweed or taking it in one of its other forms -- leaves or supplements -- can help. However, unless you have a deficiency in one of the nutrients found in kelp, consuming it is not likely to reverse your hair loss.

Bladder Wrack

Bladder wrack, one variety of seaweed, is used medicinally for many ailments, one of which is the treatment of an iodine deficiency. Your thyroid needs iodine to produce certain hormones, and without enough of this mineral, you may develop hypothyroidism. Along with fatigue and dry skin, hypothyroidism can also impair your hair growth, slowing it down or even causing hair loss. You can consume bladder wrack as a food or in the form of a supplement to support healthy thyroid function, but bladder wrack is not recommended for people who have thyroid problems, as it can make them worse.

Red and Brown Algae

Red and brown algae are good sources of vitamin A and C, both of which protect your hair follicle cells from environmental harm, which can lead to hair loss. Vitamin C is also responsible for collagen production, which is the connective tissue in your hair that keeps it strong. Finally, vitamin C helps with the absorption and utilization of iron, especially that found in plant foods. If you do not get enough iron, you can become anemic, which is one of the leading causes of hair loss.

Seaweed as a Source of Zinc

Seaweed contains a fair amount of zinc, and one of the common symptoms of a zinc deficiency is hair loss. Zinc is responsible for cell division in your follicles, and if this process is compromised, it can lead to hair loss. Many people do not get enough zinc in their diets, and eating kelp can help you consume an adequate amount. However, be aware that it is more difficult for your body to process zinc from plant foods, such as seaweed, as opposed to animal-based foods.

Precautions and Considerations

Talk to your doctor if you believe you have a mineral deficiency or if you have suddenly begun losing your hair. Tell him about your symptoms and let him know about any medications or supplements you take, always checking with him before you begin consuming different supplements or changing your diet. People with certain medical conditions, such as iodine allergies, may need to avoid seaweed and kelp, and pregnant and breast-feeding women should not consume it either, unless otherwise directed by a licensed physician.
