There are a couple of other reasons why soy is a great choice too. For one, it is really good for you, protecting your cardiovascular health by reducing your LDL cholesterol levels. For another, soy is an easy, cost-effective choice. Instead of searching everywhere for quality herbal supplements you are unfamiliar with, you can simply add some soy milk to your diet or eat some tofu.
There’s no doubt that estrogen and hair loss are connected, but there are certain factors that determine how much of an effect estrogen levels have on your hair. As one of the main visible measures of your health, hair growth is often one of the first areas affected when hormones are off-balance. Let’s take a look at the links between estrogen hormonal imbalance and hair loss.
Thyroid hormone receptors were detected in both dermal and epithelial compartments of the human pilosebaceous unit. T4 and T3 decrease the apoptosis of hair follicles and T4 prolongs the duration of anagen in vitro. Thyroidectomy delays initiation of anagen. Administration of thyroxine advances anagen, initiation of which is however delayed once toxic doses are given. Therefore, ratio of telogen to anagen hairs is increased in hypothyroidism as well as hyperthyroidism. Thus, the hair follicles are affected in thyroid disorders, and madarosis is caused due to disturbances in hair cell kinetics. Hypothyroidism is associated with generalized hair loss probably due to coarse, dull, and brittle hair with reduced diameter. The eyebrows and eyelashes may also be lost. Loss of lateral one-third of eyebrows known as Hertoghe sign is a characteristic sign of hypothyroidism. Some people also refer to it as Queen Anne's sign, after Anne of Denmark whose portrait with shortened eyebrows has been interpreted by some as indicative of the presence of goiter, even though such a fact has not been proved by any known sources of information. Madarosis may even be the presenting sign in hyperthyroidism. In hyperthyroidism, there is thinning with breaking off and shortening of hair. Madarosis can also occur in hypopituitarism, hypoparathyroidism, and hyperparathyroidism.
