Will the hair absorb nutrition?

Yes, and the longer it takes, the more nutrients it absorbs.

Hair has been growing, consuming a lot of nutrition. If the nutrients supplied by the human body to the head are absorbed by the hair too much, the nutrients in the brain will be relatively reduced.

Long hair is one of the external characteristics of women, and many women regard it as beauty. However, although flowing long hair looks good, it will affect women's intelligence.

Studies have shown that hair keeps growing and consumes a lot of nutrients. Modern medical and chemical tests show that human hair contains dozens of essential nutrients, such as iron, zinc, iodine and various vitamins.

Researchers can test a person's blood type from a hair and test various indicators of blood. This shows that hair does absorb all kinds of nutrients from the human body. If the human body supplies too little nutrition to the hair, the hair will wither or even fall off.
