How to Stop Hair Loss With Bladderwrack

Updated February 21, 2017

Bladderwrack (Fucus Vesiculosus) is a type of brown seaweed found on rocks near the coasts of North America and Northern Europe. Comprised comprised primarily of alginic acid, fucoidan and iodine, bladderwrack is often sold in nutritional supply stores as a capsule or powder supplement to treat a number of conditions, including hair loss. You can also buy shampoos and conditioners made from seaweed that claim to promote healthier hair and increased growth. Seaweed is rich in vitamins, minerals and antioxidants, all of which are needed by hair follicles to maintain healthy growth.

  1. Visit your local nutritional supply store, or go to an online retailer, and purchase bladderwrack capsules as well as seaweed shampoo and conditioner. If you cannot find it at the store, you should be able to find it online.

  2. Follow the instructions listed on the bottle. Adults should take three 200 to 600 milligram pills a day when first starting bladderwrack supplements, but the dosage is supposed to be increased to 24 pills a day, eventually.

  3. Take the pills morning, midday and night--for a total of three pills a day--with a glass of water.

  4. Wet hair and squeeze a quarter-sized amount of seaweed shampoo in your hair.

  5. Work shampoo into a lather.

  6. Rinse hair completely.

  7. Squirt a quarter-sized amount of seaweed conditioner into your palm and work into hair, making sure to fully saturate your hair.

  8. Rinse your hair fully and towel dry.

  9. Tip

    Bladderwrack is also sold in powder form at most nutrition stores.


    Bladderwrack's benefits as a hair loss treatment has not been approved by the FDA. Thus far, there have not been many reputable studies on bladderwrack usage in humans. According to the U.S. government's Medline Plus website, "safety and effectiveness [of these treatments] have not always been proven." The Medline Plus website also advises against giving bladderwrack to children and those with diabetes. Do not exceed recommended doses.
