There is a keen numerology behind the hair. What happened?

Many people wear skulls like that, don't worry. If numerology is used, it is that people with sharp bumps in the back of their heads are smart, that is, they have high IQ.

Generally speaking, the development of skeletal head type is hereditary. As long as it is normal, don't pay too much attention to it. Some people can do it because of acquired factors such as calcium deficiency, trauma, hematoma and tumor. Don't worry too much, because as long as the genetic characteristics are normal, nothing will happen. If the child is uncomfortable, he can go to the hospital for examination to rule out pathological diseases.
