Usually, a healthy adult loses 50 to 60 hairs a day, which is normal and called physiological hair loss. However, hair loss of more than 100 hairs a day is pathological hair loss, known as baldness. Nowadays, not only women are suffering from alopecia areata, but men are increasingly affected by hair thinning. More than 75% men experience severe hair loss throughout their lives. Hair loss doesn't merely cause a blow to men’s appearance, what’s worse, it damages their confidence and bring down their mental world. So, what exactly causes this nuisance for men? If you are a victim of alopecia areata, then read carefully and you will find some truth.

Androgenetic Alopeciau is the major reason.

The most common type of male pattern baldness is characterized by frequent hair loss on the forehead and top of the head, with little impact on other locations. This is the most typical type of alopecia areata - androgenetic alopecia, caused by sex hormones.

The male testes secrete a substance called testosterone (androgen), and some of this testosterone is produced in the body by an enzyme called 5α reductase to produce dihydrotestosterone (DHT), which destroys hair follicles.

DHT enters the inside of hair follicle cells and binds to androgen receptors. In this process, dihydrotestosterone will start to accumulate in some scalp areas, and some hair follicles sensitive to androgens will be stimulated by them and start to shrink, so that the growth period of hair follicles will be shortened, the differentiation of hair follicle cells will be slowed down, and the protein synthesis of hair papillae will be blocked, and eventually the hair will become thinner and shorter, until finally it loses its normal hair growth ability and degenerates into fine hair. This is why DHT is also known as a hair follicle killer.

Bad eating habits can also play an important role.

Improper diet is commonly associated with anorexia, bulimia, and overeating, resulting in lack of certain elements in the body or excessive intake of sugar, salt, and selenium, leading to hair follicle shrinkage causing alopecia.

Eat less or no fresh vegetables. A varied diet not only promotes good health, but will also largely help hair growth. Hair growth requires nutrition, which is transported by blood. If a person is chronically ill, weak, with insufficient blood and poor body nutrition, the hair will fall off short due to lack of nutrition and poor growth.

Studies have shown that excessive meat intake is an important accomplice in causing seborrheic hair loss.

Drinking large amounts of alcohol, especially scalding hot white wine, can cause hair loss by creating heat and moisture in the scalp.

Smoking constricts the scalp capillaries, which affects the development and growth of hair.

Never ignore your mental or physical health.

Experts point out that excessive anxiety, tension and other negative emotions will prompt the neuroendocrine system to release substances such as nerve growth factors, which usually inhibit normal hair growth, induce hair follicles to enter early regression and increase inflammatory damage to hair follicles. In addition, when emotionally agitated, the secretion of many endocrine hormones by the hair follicle are affected, affecting the growth of the hair shaft and the hair follicle growth cycle.

And, don't forget to safeguard your health and pay particular attention to your sleep schedule. Lack of sleep time is always inseparable from alopecia areata, as it affects the normal metabolism of hair.

Physical factors can also have an impact.

Take care to protect the health of your hair. The use of harsh hair dyes, perms and poor quality shampoos can leave hair fragile, which causes you to use wigs at a young age.

Water quality is also a major cause of hair fall. The water in some countries contains calcium carbonate and is weakly alkaline, while the water quality for healthy hair growth is weakly acidic. The longer you use hard water to shampoo your hair, the greater the need you have to use a toupee.

These are a few of the major causes of male hair loss. It can be found that both congenital intrinsic factors make hair loss a possibility and some inappropriate practices in men later in life can lead to hair damage and eventually baldness. Only when we figure out the real causes of hair thinning, we can find the corresponding methods to relieve the hair loss. It is more important that we pay attention to as many aspects as possible to prevent more severe hair loss since both intrinsic and extrinsic can lead to alopecia areata. We can start with these four reasons to save our hair as much as possible. Certainly, some factors are simple to deal with, on the contrary, some can not be avoided, at this time, a wig or a toupee is your necessity. It's convenient and aesthetically pleasing, and in modern times, has been the first choice for the majority of balding men.
