Does growing long hair really help absorb nutrients from the body?

In life, we often hear people say that people with long hair have short knowledge. Many people believe that people with long hair are dumber because long hair absorbs nutrients for the brain. Many people are afraid to keep long hair because of this, and many pregnant women cut their hair for fear that the hair will absorb nutrients and affect the baby. Does long hair really absorb nutrients? Today, I will give you a scientific answer to this question so that you can eliminate your doubts and keep your long hair with confidence.

From the perspective of health preservation, does long hair really absorb a large amount of nutrients from our body? In fact, nutritionists have never agreed with this statement. After human hair "breaks out of the skin" from the follicle, it becomes the hair shaft, which is the part of the hair exposed on the surface of the scalp. The hair shaft is dead keratinocytes and does not have metabolism itself, and of course does not consume nutrients. That is to say, only healthy hair follicles need to consume certain nutrients when growing hair, while other parts of the hair do not consume nutrients. Regardless of whether the hair is long or short, healthy hair follicles will grow hair "regularly and quantitatively".

Some girls always cut their hair short because their hair becomes split and dry. This practice is also incorrect as it can only treat the symptoms but not the root cause. The key is to strengthen hair care in daily life. Don't try to perm or dye your hair. It is best to air dry your hair after washing it. It is best to wear a sun hat when going out. Eat more foods that can darken hair and replenish blood, such as black rice, peanuts and so on. All in all, long hair does not compete with our body for nutrients, so it is okay to keep the hair longer.

The above is the answer to the question of whether long hair can absorb nutrients for the body. Now you will no longer be hesitant about whether to keep your hair. Now that we have the scientific answer, we should correct our misconceptions. For pregnant mothers, there is no need to cut their hair short deliberately. Don't believe the rumor that long hair will compete with the fetus for nutrients, which has no scientific basis.
