An equal balance of hormones is required to maintain healthy hair. One of the most critical hormones in maintain healthy hair is testosterone; known commonly as the predominant male hormone. Women also carry this hormone and when they go through menopause the body makes less of the female hormone estrogen to counter it. Consider taking supplemental estrogen to balance this out and to promote hair growth. Estrogen is present in certain plants and herbal remedies such as 'dong quai', 'ashwaganda' or a milder variety of 'damiana' are all suggested plant-based estrogens. If you are concerned about an under active thyroid during menopause, then you may need iodine-rich veggies to boost your system. Though it may not sound appetizing kelp could do the trick to nudge your thyroid back into shape. If the hormone you're looking to block is DHT (dihydrotestosterone) then try 'saw palmetto' to help deter it from forming in the first place. If you need a little balance in your diet, and this is the cause of your hair loss, it's time to increase your intake of essential fatty acids to aid your membranes back to health. Essential fatty acids can be consumed in the form of fish oils, which are very common, flaxseed oil is as well a natural supplement to maintain rich, healthy hair.
