I have some red hair on my head. What happened?

This is a good sign. It is said that Xiao Taihou has three red hairs on his head, which can make him happy. (superstition)

This is related to nutrition, but don't worry too much. It's normal. Almost everyone has it. The savior is to be square. Don't worry about everything, or worry about one thing all the time. Eating badly and sleeping badly will aggravate it. If there are more and more red hair, it is recommended to see a doctor for observation for a period of time.
