Does a child s hair absorb more nutrients the longer it gets?

Your daughter's long hair proves that the nutrition is good! If the nutrition is not good, the hair will not be so good! Affect intelligence, this should be the rumor you heard!

Although long hair is beautiful, it is one of the factors that affect intelligence, which is probably not well known. The conclusion is based on the fact that hair grows all the time and consumes a lot of nutrients from the human body all the time. Medical and chemical tests have shown that human hair contains dozens of essential nutrients, such as iron, iodine, zinc, and various vitamins.

Researchers can test someone's blood type from a single hair and test for various indicators of blood. This shows that hair absorbs various nutrients from the human body, and if the human body supplies too little nutrients to the hair, there will be hair withering and even falling out. The nutrients supplied to the hair cannot be stopped for a minute, and it is difficult to calculate the amount of head nutrients consumed by the hair over time.

If too much of the nutrients that the body supplies to the head are absorbed by the hair, the nutrients to the brain are relatively reduced. Over the years, the brain will be deficient. The lack of brain nutrition will directly lead to dizziness and affect people's intellectual development.

Therefore, in general, women suffer from dizziness more than men, and more girls with long hair than girls with short hair.

Long hair doesn't absorb nutrients, and short hair doesn't absorb nutrients for the following reasons:

1.After human hair grows in the hair follicle, it is "topped" out** and becomes the hair shaft, which is the part of the hair that is exposed on the surface of the scalp. The hair shaft can be thought of as dead keratinocytes that do not have a metabolism of their own and certainly do not consume nutrients.

2.Only healthy hair follicles need to consume a certain amount of nutrients when they grow hair, while the rest of the hair does not. Regardless of hair length or length, healthy hair follicles grow hair "in regular quantities".

Therefore, long and short hair does not increase the nutritional needs of hair growth.

3.Compared with the nutritional consumption of physical development, brain development, and pregnancy of the fetus, the nutritional needs of hair are only a small part, and they are also a fixed part of the overall nutrition of the body. Even if you don't trim it, a normal person will have about 50-100 hair loss every day, and the number of new hairs every day is about the same as the number of hair loss, which belongs to the normal metabolism of the human body.

The following nutrients can contribute to healthier hair.

1.Protein. Hair is made up of protein, and eating more protein can make your hair thicker. Regular supplementation of fish, poultry, beef, beans, lentils, nuts, seeds, and dairy products such as yogurt and cheese is recommended.

2.Iron. 3.Vitamin C

Vitamin C can prevent hair split ends and breakage, and it is recommended to eat more citrus, guava, sweet potato, kiwifruit, and papaya.

4.-3 fatty acids.

If you want a healthy scalp, fat is the key. If the diet does not contain fatty acids, the hair can become dry and inflamed, leading to hair loss. In particular, -3 fatty acids moisturize the scalp and hair follicles.

It is advisable to eat more fatty fish, such as salmon and trout; If you don't like fish, you can choose rapeseed oil and walnuts.

5.Zinc. Zinc is important for the formation of keratin, which is the main component of hair. When intake is insufficient, hair can become dry and dull. But many women don't have enough zinc in their diets. It is recommended to eat more red meat, pumpkin seeds.

6.Vitamin A

Vitamin A allows the hair's skin glands to secrete oil, making hair less dry. Sweet potatoes, mangoes, carrots, and pumpkin all contain adequate amounts of vitamin A. Vitamin supplements are actually not as effective as dietary supplements.
