Why is the top of the head prone to hair loss?

Many people have limited knowledge about hair loss. When they experience hair loss, they will buy some health products or try some folk remedies. Not only do these fail to cure the hair loss, but they may make the hair loss worse. There are many types of hair loss according to the different causes. Among them, androgenic alopecia causes the most people, more than 90% of them. Androgenic alopecia occurs on the top of the head, the hairline slowly moves back, and the hair begins to become thin and soft, which is not easy to detect. By the time you notice that you are losing hair, it has already reached a certain size.

Why does hair loss only occur on the top of the head? In fact, there are several reasons. The first is blood circulation. The head is the highest part of the human body. The blood pressure is lower, and the blood flows slower in the head. The blood flows horizontally in the scalp, which is prone to precipitation and blood lipid adhesion. If the blood flow to the head is not smooth and the capillaries are blocked, the growth of hair will be affected. The capillaries on the forehead and top of the head are the most fragile and prone to blockage, so hair loss is more likely to occur on the top of the head and forehead. Secondly, damage to the scalp can also lead to hair loss. Generally, some minor injuries can be repaired by the scalp cells within 48 hours; but if it is subjected to continuous physical or chemical damage, it will interfere with the normal metabolic cycle of the cells and cause a large number of cell death, such as using inferior shampoo, frequently dyeing and perming hair for styling, using a hair dryer to dry hair, etc. All of these will affect the normal growth of hair follicles, and may even cause hair to fall out and the hair follicles to completely close.

Androgenetic alopecia is the main cause of hair loss in men. DHT plays a key role in this. DHT is produced by testosterone (androgen) in the human body through the action of 5α-reductase. Men have more testosterone (androgen) in their bodies, and androgen plays a very important role in human sexual development. However, the DHT it produces is not very friendly to hair follicles. It will affect the normal development and growth of some hair follicles. It will make the hair follicle cells lose their activity, and the thick hair will become thin and soft and easy to fall off, until the hair follicles finally stop synthesizing hair, resulting in large-scale hair loss and exposed scalp. Why are the back and sides of the brain not affected by DHT? This is related to the differences in hair follicle cells. The hair follicle cells on the top of the head and forehead have congenital defects and are more sensitive to DHT. Some people start to lose hair from the hairline. The fundamental reason is nothing more than genetic genes and dihydrotestosterone.
