Women do not inherit baldness, so, in a female hair loss is “always an abnormal symptoms”. Except for few cases caused by an infection, in the majority of women the hair loss is always due to a hormonal cause. They are two hormonal circuits that can cause excessive hair loss: thyroid hormones decrease, or an excess of testosterone, or male hormone, produced by the ovary whose secretion is overstimulated by insulin.
When the cause is the lack of thyroid hormones, hair loss occurs throughout the scalp, especially in the back of the head. The hair is very thin and extremely dry. The root of the hair is so dry, even after many days without washing, dry continues. When low levels of thyroid hormones is noted, proper leveling of these hormones stop hair fall and returns the oily secretion of the root. Foods do not have any influence on the hair loss when this is caused by thyroid deficit.
On the other hand excess testosterone is the other possibility diagnosed and is the cause of the hair loss in mostly (approximately 85%) of the patients. It is an overstimulation of the ovarian secretion of testosterone induced by insulin. In these patients a defect of insulin receptors found in the muscle, which courses with completely normal levels of blood glucose, accompanied by excessive levels of insulin, which act in the ovary encouraging an exaggerated testosterone secretion.
Why does the hair fall?
In these patients, unlike what happens in those with thyroid deficiency, the hair is very oily, especially the root. These patients sometimes have to wash your hair twice a day, because in a few hours be full of fat. The hair loss predominates in the coronal and frontal region of the head. Excess testosterone induced by insulin also stimulates the secretion of fat by the sebaceous glands of the face and back, causing acne in these patients. In addition, they may have HIRSUTISM and menstrual delays, since Testosterone stimulates hair growth in the breasts, below the belly button and on the Chin, while it affects ovulation producing a multifollicular or polycystic ovary appearance.
Contrary to what happens in cases of hypothyroidism in patients who have excess of testosterone, hair loss worse when they consume flours, sugar, potato, cassava, sweet potato, rice and chocolate. This is due to the elevation of insulin which presents by eating flours and sugars, stimulates the secretion of testosterone in the ovary, accentuating the fall of hair. Any condition which will accentuate the defect of insulin, responsible for the exaggerated elevations of insulin and testosterone receptors, will perpetuate the loss of hair in these patients.
Obesity, age, consumption of carbohydrates at night, worsen this system and aggravate the fall of hair. Cortisone, steroids and contraceptives, some more than others, are also adverse.
As this hormonal disorder also causes menstrual irregularities, indicated many of these patients contraceptives to induce regular rules. With this medication not only hides the disorder in the background, but it also worsens the defect of insulin receptor. So, to suspend the tablets, usually both acne, and menstrual arrears and fall hair is emphasized more.
Sometimes, these patients with excessive levels of testosterone and insulin are subjected to different local treatments to reduce hair fall. Indicate them different solutions for wash and apply on the scalp, special shampoos, and put up shots. But the results are very poor, and as long as the problem persists, the hair will continue to fall.
Many, even attribute to stress a causal effect of the hair loss. But they do not explain how it is that people with stress that hair does not fall. In medicine, if the cause is not resolved, will not solve the problem.
On the contrary, if we correct the defect of insulin receptor, testosterone levels will be normal. Secretion of fat at the root and hair loss will decrease rapidly. In addition, thus also solve acne, HIRSUTISM and the rules will be regular. In addition we will avoid other consequences, such as weakness, obesity, addiction to carbohydrates and increase triglycerides.
