The thyroid It is an endocrine gland responsible for the production of a series of hormones that affect almost all the organs of the body, intervening in several important functions of the organism, among which are cell development that affects the natural growth of hair follicles. That is why, suffering a thyroid disorder, with a thyroid gland with too high or too low hormone production, contributes to subsequent hair losssince, according to Hair Hospital, the largest corporation in the hair sector, this gland is responsible for functions such as stimulating hair follicles, regulating hair cycles, balancing the activity of the sebaceous glands and the production of sebum, and promoting hair strength. “The thyroid It is a small butterfly-shaped gland located in the front of the neck, below the Adam’s apple, which produces and releases thyroid hormones, called thyroxine (T3) and triiodothyronine (T4). These hormones are responsible for regulating our metabolic cycle and body temperature, the speed at which our cells work and other tasks such as heart rate, nutrient assimilation, brain development or mood. For this reason, our hair can be affected by suffering from hyperthyroidism or hypothyroidism, and hair loss caused by this problem can occur, “explains Dr. Alberto Sánchez, from the Hospital Capilar clinic. So, the natural cycle of our hair follicles will depend, to a large extent, on the proper functioning of the thyroid and, therefore, both in hypothyroidism and hyperthyroidism, hair loss will originate due to the alteration, in one way or another, of this hormone, essential for the growth of the hair follicle. This imbalance, which suffers around the 10% of the Spanish population, fundamentally affects women, many cases of hyperthyroidism being perceived in hormonal periods such as pregnancy or postpartum due to the increase in estrogen levels; while hypothyroidism is more common in other stages such as menopause. In this regard, Dr. Sánchez highlights that “without enough thyroid hormones, many of the body’s functions slow down, while with an excess of them, they speed up. All the cells of our body have receptors for thyroid hormones, so the alteration of this hormone secretion may have repercussions in the rest of the organism”.

Hair loss originates due to thyroid alteration

In this way, the hypothyroidisma disease caused by total or partial inability to secrete thyroid hormoneswill affect the development of the hair at the root, producing a chronic and diffuse hair loss in which the telogen phase will increase and the anagen phase will be delayed, observing a loss in the quality of keratin, as well as drier and more brittle hair. Also, depending on the severity of the hypothyroidism, hair loss can manifest itself all over the body, with loss being evident on the outer part of the eyebrows and body hair. However, in the hyperthyroidism a excessive release of hormones in which a diffuse hair loss will also originate caused by the acceleration of the capillary cycles, giving a more active fall in which the hair will be born and will fall out faster than usual; In addition to leading to other general symptoms such as palpitations, increased respiratory rate, weight loss, nervousness or sweating that, at the capillary level, may cause the appearance of folliculitis. However, unlike hypothyroidism, in this disease hair loss is limited to the head, without affecting the rest of the body. However, this hair loss that occurs in both hypothyroidism and hyperthyroidism is usually reversible if the underlying problem is treated in time, so it will be essential to consult a specialist who performs a capillary diagnosis and prescribe appropriate tests to determine the root of the problem. “Hair loss can be corrected once thyroid function returns to normal, although this will require a treatment according to each case. For example, most cases of hypothyroidism are due to an immunological problem called Hashimoto’s disease, therefore it is essential to recognize why this condition occurs, also evaluating digestive intolerances and administering, on the other hand, hair treatments to increase capillary density”, details Dr. Sánchez.

Diet, a key factor in dealing with this problem

When dealing with this disease, experts advise keeping a balanced and balanced diet, since the hormonal imbalance that occurs in this disorder can reduce the ability to correctly absorb nutrients. Therefore, it is recommended to take vitamins A, B and C and to emphasize foods that contain iodine, magnesium, selenium or zinc or iron, as thyroid problems can lead to low ferritin, with 50% of people with hypothyroidism being iron deficient. “We must not forget that this problem has an essential relationship with the normal flora of our digestive system, which is why, in many cases, foods that cause intolerances such as gluten, soy or lactose must be dispensed with,” concludes the specialist.
