Hair loss is one of the most common health issues which both men and women have to undergo for several reasons. When men experience a progressive loss of their hair as an integral stage of male pattern baldness, it is called receding hairline. This condition starts with the thinning of their hair initially on either side of their foreheads. Eventually, it turns to be a bald-pated pate.
There are several factors which increase the likelihood that men have to have this type of bald patch on top of their head. While genetics is said to play the most influential role in causing the issue, other factors also contribute to the loss of hair. People who are over 25 years old are usually vulnerable to the loss, but some people also suffer from it even at their teen ages.
What is the most significant cause?
Androgenic alopecia is known to be the most influential factor which is driven a hormone called dihydrotestosterone or DHT. It is the principal element which usually acts as a male sex hormone. During puberty, this hormone projects the substantial growth of secondary sex characteristics. Consequently, the hormone outlasts its utility and sometimes leads to unwelcome side effects which mostly include the inhibitory state of continuous hair growth.
Exceptions to this hormonal activity:
It is not essentially true that all people suffer from a receding hairline due to DHT functionality. DHT production rate varies from man to man. The production rate slows down in some men while it may gain an excessive growth in some men. In case of an excessive production, the hormone gain formations in different places in their body which may include the hair follicles. At one point, the hormone usually binds in adequate amount to their hair follicles. It chokes off the blood flow to the follicles and starves the hair of its required nutrients. Eventually, hair falls out.
In addition, there are other crucial factors which may also lead to receding hairline. Those factors may include disease, psychological stressors and enzyme activity.
Hair loss is often considered as more of a genetic issue than other factors. Androgen receptor or AR is the first specifically identified gene to work behind hair loss in men. How fast one’s hair loss will be depends on how strong that person’s AR gene is. Although the most fundamental studies suggested that the gene would pass down from a mother to her son, today’s research suggests that men can also inherit this gene from their father as well. Another study told that the 20th chromosome of male body hosts another gene which can also trigger baldness even for people who do not inherit a strong Androgen receptor gene.
Sudden stress especially for women:
Unexpected illness, major surgery, traumas, poisoning and even childbirth can also increase shedding of hair.
Decrease in hormone level:
When estrogen hormone levels decrease in women and testosterone hormone levels decrease in men, both sexes are likely to experience a receding hairline.
Wrong or inevitable use of medications:
People have to use drugs to fight their blood pressure, gout, cholesterol and heart diseases. Besides, they have to take drugs which often contain a large amount of vitamin A and anti-depressants. All these accelerate the loss of their hair. Chemotherapy is another widely recognized factor to increase hair loss. This therapy is applied to treat cancer.
Several types of infections and diseases:
Diabetes, sebaceous cysts and lupus are also responsible for hair loss. Moreover, there are some sorts of diseases which usually weaken our overall immune system. These diseases are also responsible for a receding hairline. Further issues may arise from several other diseases or conditions including burns, disorders of the thyroid gland, trichotillomania, alopecia areata and adrenal gland tumors.
