The difference between white hair roots and white hair ends

The quality of hair determines a person's appearance and also reflects whether the human organs are healthy. It is best to use warm water when washing your hair, and use less hair dye. You can also eat more black grain foods, such as black sesame and black beans. Eat more fruits and vegetables, keep a happy mood, do not use irritating shampoos and skin care products, exercise more, and stay healthy.

What determines hair color is the amount of pigment particles in the hair, which is related to the development and growth of pigment cells in the hair root papilla. When hair turns from black to white, it is generally due to the decline of the function of the hair pigment cells. When they decline to the point where they can no longer produce pigment particles, the hair turns completely white. In normal people, hair pigment cells begin to decline from the age of 35. Some people have white hair in their 20s, which is medically called juvenile graying, commonly known as "premature graying".

The causes of premature graying of hair are rather complex, and are related to both genetic and physical factors as well as various acquired factors.

Acquired premature graying of hair. There are many reasons for this: malnutrition, such as lack of protein, vitamins and certain trace elements (such as copper), can cause hair to turn white; some chronic wasting diseases such as tuberculosis, due to nutritional deficiencies, can also cause hair to turn white earlier than normal people;

The hair of some patients with long-term fever will become yellow and brittle, or even turn white and fall out; some endocrine diseases, such as pituitary or thyroid diseases, can affect the ability of pigment cells to produce pigment granules and cause premature graying of hair; encephalitis, nervous system diseases, etc. can also cause hair to turn white; the skin, hair, and eyebrows of patients with albinism are all white; the skin-whitening disease "vitiligo" will also turn hair white if it occurs on the scalp; some people believe that the more you use your brain, the earlier your hair will turn white; some young people have a lot of white hair in a short period of time, which is related to severe mental trauma or mental fatigue such as excessive anxiety and sadness.

If the roots of the hair are black and the ends of the hair are white, it usually means that the hair is getting darker. If it is getting white, the roots of the hair will also turn white.

It may also be related to certain nutritional deficiencies. You can supplement some nutrients appropriately, such as cystine. Cystine is a type of amino acid and a nutrient required by hair keratin. You can also supplement trace elements copper and zinc. Hair lacks copper and zinc, which can lead to a reduction in the synthesis of melanin.

Hair, generally written as hair, refers to the hair that grows on the head. Hair is not an organ and does not contain nerves or blood vessels, but it contains cells. In addition to making people more beautiful, hair mainly protects the brain. Soft and fluffy hair is elastic, can withstand lighter collisions and help evaporate sweat on the head. The average person has about 100,000 hairs. Among all the hairs, head hair is the longest, especially on women with long hair. Some can grow to 90-100cm, or even 150cm, but generally do not exceed 200cm.

Avoiding mental crises and maintaining relative psychological balance are crucial to preventing premature graying of hair. Pay attention to the quality of diet and eat more foods rich in high-quality protein, trace elements and vitamins. You can choose fresh fish, milk, animal liver and kidney, black sesame, edible mushrooms, seaweed, fresh vegetables and fruits, etc.

Under the guidance of a doctor, using vitamins, folic acid, Chinese medicines such as Polygonum multiflorum, wolfberry, mulberry, etc. as appropriate can help prevent or delay the generation and development of gray hair.
