Does hair absorb nutrients from the human body?

There is a saying from the ancients: "Your body and hair are given by your parents." It means that you should not damage your body easily, including your hair, which are given by your parents. This also indirectly shows that hair, like the skin of the body, also needs to absorb nutrients from the human body. Hair absorbs nutrients from the body through hair follicles and converts them into nutrients needed for hair growth. Take a bath and wash your hair frequently to keep diseases away from you.

Hair needs nutrition in the process of "growing". Hair follicles always need raw materials to synthesize hair. The main component of hair is keratin.

After the hair grows out and becomes solid, that is, when you see these hairs, they are already dead, just like your nails that have grown out (they have similar components), they will no longer absorb nutrients from the body.

Hair becomes dry and yellow because the surface structure of the hair is "worn" in daily life, the surface is not smooth, and it looks dry naturally.

The function of conditioner is to smooth the hair scales on the surface of the hair through physical action, rather than providing nutrients for the hair to absorb and increase its life value... The hair is already dead and cannot absorb nutrients.

The speed of hair growth varies from person to person. Some people's hair grows faster and thicker than others, but this has nothing to do with whether the person has long or short hair. So there is no basis for the claim that long hair absorbs more nutrients.

Hair is a part of the human body, just like other parts of your body. You don't worry about whether your hands will absorb your nutrients or whether your thighs will take away your nutrients. Why would you worry about your hair absorbing your nutrients? The body is a very organized, disciplined, arranged and planned biochemical experimental center. It will use the nutrients it ingests rationally and always base it on ensuring the supply of the most important organs. Hair growth requires some protein. If a person's nutritional status is poor and the food he eats is monotonous, his hair will reflect these problems. A head of shiny and thick hair also indirectly represents good physical condition.
