Having a full head of hair at a young age is a sign of good health. It is an outer manifestation that the body is receiving its proper nutrients. This is because the hair follicles are among the last to receive nourishment from the body. It will supply other areas that perform general body functions first. A body that is well nourished will have enough to provide the hair follicles after it has satisfied the requirements of its vital organs. If it does not receive the right amount however, the hair follicles will be the first ones to be deprived in the distribution of nutrients that causes the eventual hair loss.
A problematic thyroid can lead to a hormonal imbalance that could result in balding. There are two types of this occurrence. The first is hypothyroidism or when the thyroid produces less of the hormones the body needs. An underactive thyroid gland disrupts the normal flow of chemical reactions in the body causing obesity, heart disease and other kinds of health problems if left untreated. The second kind is hyperthyroidism or an overactive thyroid. It can cause weight loss, irritability and sweating. This is due to the overproduction of the gland called thyroxine.
Hair loss should not automatically be attributed to a problematic thyroid. There are other causes that could also result in balding. Consulting with a doctor is required in order to get the proper diagnosis for this symptom.
A similar hair loss condition is called telogen effluvium. It is caused by a rapid shift between the anagen and telogen hair growth cycle. This is usually triggered by life events or stressful situations such as childbirth, divorce, loss of a loved one or major surgery. Hair is shed in clumps about three months after the traumatic incident. It will usually regrow on its own once the hormonal levels have stabilized. This is identical to having a problematic thyroid.
Alopecia areata is another hair way that a person could experience hair loss. This is evidenced by the random appearance of circular bald patches upon the scalp. An exact explanation why this occurs is unknown. It may be due to stress or other factors that have yet to be discovered. What was established is that it is an autoimmune condition where the body mistakes the hair follicles as a foreign body. It sends white blood cells to attack these hair follicles and causes its shrinkage. This can progress to a more severe case of total hair loss upon the scalp known as alopecia areata totalis.
Perhaps the most common among all the manifestations of hair loss is androgenic alopecia. There is a ninety-five percent chance that a person who is experiencing hair loss is undergoing this condition than all other possible occurrences. It is a gradual form of balding which usually begins in a man’s thirties and a woman’s forties. Its slow progression will take years before the hair loss reaches its latter stages. Among men, this appears as a horseshoe-like hair pattern with only the lower sides and back of the head having hair. Women on the other hand will rarely have a receding hairline. Hair loss will manifest itself as diffuse thinning upon the vertex region of their scalp.
These are among some of the many balding conditions that could be considered along with a problematic thyroid. Note that neither hyper nor hypothyroidism will result in complete hair loss. It is only the hair density that will be affected which would often look like diffuse thinning. The scalp can regrow hair by itself once the hormone levels stabilize.
