What are some causes of seborrheic alopecia in men?

In this era of rapid development, men may have greater life pressure. Some men often start to lose their hair in middle age. There are many reasons for hair loss. High life pressure can easily cause hair loss, and poor sleep quality may also cause hair loss. So what is the cause of male seborrheic alopecia? Let's take a look at the cause of male seborrheic alopecia.

Causes of seborrheic alopecia:

(1) Male hormones

Modern medicine has confirmed that people with seborrheic alopecia generally have more male hormones. This is mainly because the male hormones secreted by the testicles enter the blood circulation, reach the scalp, and are converted into toxic substances that stimulate the hair follicles. The energy metabolism and protein metabolism of the hair follicles are impaired, resulting in hair loss.

(2) Genetic factors

The genetic gene of seborrheic alopecia is dominant in men, and the pathogenic factors can be directly inherited from one generation to the next, so seborrheic alopecia is more common in men.

(3) Age

As men age, the incidence of fat alopecia gradually increases. Fat alopecia often occurs in young men between the ages of 17 and 20, with the peak incidence at around 30 years old. As age increases, although the incidence decreases, the symptoms worsen and eventually turn into baldness.

(4) People who engage in intense and complex mental work

Mental stress is high and the brain consumes a lot of energy, which stimulates the body's autonomic nervous system and hormones to make adaptive adjustments to maintain normal body temperature, metabolism, and immune function. It secretes more male hormones, which enhances people's analytical and judgment abilities, making them alert and intelligent. At the same time, it makes people's temperament more impatient and their sebaceous glands secrete more vigorously. The sebaceous glands on the scalp are the most developed compared to other parts of the body. In this case, the secretion is more, which provides conditions for the massive reproduction of lipophilic fungi and head mites on the scalp. The lipophilic fungi on the scalp multiply in large numbers under the premise of large secretion of sebaceous glands. The over-active lipophilic fungi obtain nutrients from the hair follicles and discharge their metabolites there, stimulating the hair follicles and scalp to cause chronic inflammation - seborrheic dermatitis. If seborrheic dermatitis is not treated in time, the bacteria at the hair roots will grow and multiply to produce a lytic enzyme that dissolves the hair roots into incomplete and loose hair roots, causing the hair follicles to gradually atrophy and the hair growth function to gradually decline. The hair gradually decreases until the hair becomes completely bald.

(5) Head mites

It is a tiny parasite that cannot be seen by the naked eye. Hair experts have discovered that head mites, a tiny, fat-loving animal, are also the culprit of hair loss, just like genetic or hormonal imbalance. It parasitizes in human hair follicles and feeds on sebum. After eating, it secretes a lipase to help digestion. This enzyme will further decompose and erode the sebaceous glands in the scalp, blocking the hair follicles, causing the hair follicles to lack nutrients and shrink, resulting in hair loss or baldness.

The above are some of the causes of seborrheic alopecia. Seborrheic alopecia is a permanent type of hair loss. The hair will not regenerate after it falls out. Seborrheic alopecia is related to androgen, but it is not the only relationship. It has a lot to do with sebum secretion. Women may suffer from seborrheic alopecia, but it is less common than men.
