Why do boys lose their hair?

When middle-aged men reach a certain age, they will experience baldness on their heads. Baldness will not only affect the overall temperament of a middle-aged man, but also hit his self-confidence. Therefore, in order to prevent baldness, boys should prevent hair loss from a young age. However, in life, many boys will find that they like to lose their hair. Why do boys like to lose their hair?

1. Excessive hormones cause men to lose their hair. Which hormone causes men to lose their hair? Is it testosterone, which is the most abundant, or dihydrotestosterone, which is derived from testosterone? In fact, about 5% of testosterone will be converted into dihydrotestosterone by a catalyst called 5a reductase. Although the amount of this hormone is relatively small, it is very powerful. The ability to bind to the androgen receptor is testosterone. It is more than ten times as much as the prostate and the scalp, where it is most active. Some people are naturally more sensitive to it due to genetic factors. This substance is active in the scalp and combines with the androgen receptors to return to the hair follicles and atrophy, causing the growth cycle of the hair follicles to gradually shorten, and the hair growing from here becomes thinner and thinner, and eventually the hair becomes thin and degenerates into down until it disappears.

2. Excessive nervous stress can also cause men to lose their hair. Men have to bear more stress from their families and society, so their nerves are in a state of tension for a long time. When the nerves are in a state of tension, the body's arrector pili muscles contract, the hair stands upright, and the capillaries that transport nutrients to the hair follicles are damaged, causing poor blood circulation in the scalp, which changes the hair growth environment. If the nervous stress is too high, it can also cause excessive sweating and sebum secretion, causing dandruff on the scalp and reducing the quality of the scalp's living environment, thus causing men to lose their hair. Most men's hair loss caused by nervous factors is only temporary, and most can heal on their own without the need for medication.

3. Genetic factors cause hair loss in men; hair loss caused by genetic factors is generally called permanent hair loss. At first, the edges of the hair on the forehead gradually shrink back, the hair on the forehead and the top of the head gradually becomes thinner, and finally only the hair on the back of the head and the sides of the head is left.

4. Certain diseases cause men to lose their hair; men lose their hair due to high fever diseases, but X-rays, ingestion of metals or drugs, malnutrition or certain skin diseases, chronic wasting diseases and endocrine disorders can also cause symptoms of hair loss in men.

The above is the knowledge about why men lose their hair and why men lose more hair. In addition to the factors introduced above, there are many other factors in life that can cause men to lose their hair. Dermatologists remind you to consult a hospital first when you have symptoms of hair loss, find out the cause of hair loss and then take the correct treatment. Blind treatment is likely to aggravate the symptoms.
