The correct method of combing your hair can make your white hair black. The nutrition of hair comes from blood. The growth, shedding and color quality of hair can reflect the ups and downs of human qi and blood, and reflect the health of the body to a certain extent. If you comb your hair often, you will not have white hair.

there are two main ways to comb your hair, one is to comb it with your fingers, and the other is to comb it with a comb.

Finger-combing method: First, bend your fingers slightly, palm to head, ten fingers close to the scalp, and comb and massage from front to back. People with thick hair can insert their fingers into their hair for circular massage with their fingers, and gradually push it backwards. People with less hair can comb it to the end with their fingers, not too fast, and the number of times is as good as possible.

when combing your hair, you should pay attention to choosing a comb with short and sparse teeth, which is easy to remove grease. It is not advisable to use a comb with too dense and pointed teeth to avoid damaging your scalp. It is suitable to use horn comb, wood comb (mahogany comb is the best) with round head teeth comb.

Prevention of gray hair

1. Stay optimistic. Being optimistic about life and keeping a happy mood will help to make your hair black and beautiful.

2. Strengthen nutrition. Hair will turn white if it loses the nutritional supply to maintain normal pigment. Many scientific studies have proved that nicotinic acid, p-aminobenzoic acid, carotene and citric acid in vitamins have important effects on the formation of pigments and their metabolism. If there are obstacles or changes in their absorption, storage and utilization, the moss can turn into hoarfrost. In the diet, foods containing vitamins B1, B2, B6, nicotinic acid, etc. must not be lacking for a long time, otherwise, the hair will turn from black to gray and then white. Scientific research in recent years also shows that. Lack of some trace elements, such as copper and iron, can also make hair white.

3. Treat diseases. Some infectious diseases and chronic focal inflammation. Such as dental caries, tonsillitis, suppurative sinusitis, etc., can also cause white hair through bacterial action and nerve reflex. In endocrinology, pituitary gland, adrenal gland and autonomic nervous system are closely related to the secretion function of black excitatory hormone, which promotes the formation of melanin. Endocrine is normal, the secretion of black excitatory hormone is more, the formation of melanin is more, and the hair color is darker; On the contrary, white hair will grow in clusters. In addition, sexual dysfunction can also cause white hair. Therefore, in order to prevent gray hair, the above diseases must be treated as soon as possible.

4. Massage the scalp. In order to prevent white hair, you can stick to drawing a small circle on the scalp with your index finger and middle finger after getting up in the morning and before going to bed, and rub the scalp: first from the forehead to the back occipital part, and then from the forehead to the occipital part through the temples on both sides. Massage for 1-2 minutes each time, rubbing back and forth for 3-4 times per minute, and then gradually increasing to 5-1 minutes. This massage can accelerate the local blood circulation of hair follicles, so that the hair papilla can get sufficient blood supply. In this way, the nutrition of pigment cells in the hair bulb is improved, the cell activity is enhanced, and the division is accelerated, which will be beneficial to the secretion of melanin and the blackening of hair.

5. Be diligent in combing your hair. Combing one's hair frequently is also a physical massage method, which originated from Chao Yuanfang, a medical scientist in Sui Dynasty. In Treatise on the Causes of Diseases and White Hair, he thinks that the root cause of white hair is weakness and malnutrition, so he has the idea that "a thousand times more than combing your hair, your hair will not turn white", which means that combing your hair frequently can prevent your hair from turning white. This is very scientific: combing your hair diligently can not only keep the scalp and hair clean, but also accelerate the blood circulation and increase the nutrition of the pore head, thus preventing the hair from turning white.
