First of all, male baldness is obviously a physical defect; But baldness has both advantages and disadvantages, and it does have this physiological advantage that cannot be underestimated, and its merits and demerits are clear. Bald men should foster strengths and avoid weaknesses. Of course, people with severe baldness can receive treatment and even have hair transplants.

Clever: As the saying goes,' no grass grows in the downtown area, but no hair grows on the smart head'. Practice is the only criterion for testing truth. A large number of examples prove that most bald people are smart and have high IQ.

After puberty, men secrete a lot of androgen. Androgen testosterone makes human sebaceous glands secrete sebum vigorously, which makes dermal papillae nutritious, and makes hair appear for a long time and grow well. The young man has black hair and a radiant face. However, there is a 5-α reductase in human body, which will convert testosterone into dihydrotestosterone, which will make the blood vessels of the dermal papilla contract, and the dermal papilla contract smaller, leading to hair loss. The course of the disease progresses slowly. First, hair loss starts from the frontal angles on both sides, the front hairline gradually recedes, the forehead becomes higher, and the top of the head is bald. This is androgenetic alopecia, commonly known as' baldness' and' baldness'. Stress and excessive dieting can also accelerate baldness due to lack of nutrition in hair.

Scientists in Britain, Iceland, Switzerland and the Netherlands took 1 125 European men as research objects, and they found these two mutant genes in the DNA of chromosome 20. The researchers in this study found that about 14% of men have these two gene variants. The incidence of androgenetic alopecia in men with these two genes is above 70%, while the incidence of androgenetic alopecia in men without any gene is only 10%.

According to Japanese reports, men secrete a lot of androgens during the embryonic period. Androgen can promote the development of the right hemisphere, and the right hemisphere is mainly responsible for the image thinking of spatial recognition such as images and geometry. Spatial recognition ability is closely related to mathematical ability. Therefore, people who are prone to hair loss and baldness have much higher mathematical ability than ordinary men. Most people are right-handed, the left hemisphere is well developed and utilized, and the right hemisphere is not fully developed and utilized; Since androgen can promote the development of the right hemisphere, it is obviously beneficial to the development and utilization of the right hemisphere. It is obviously beneficial to the development of personal wisdom and potential.
