As a hair doctor, I would like to remind everyone warmly that the cause of white disease is complicated, and there is still no targeted drug treatment for white hair! Don’t listen to the kind of propaganda that the hair can turn black in seven days and one month, so as to avoid being deceived and spending money in vain. But don’t be discouraged, stick to a healthy lifestyle, white hair has a certain chance of turning black! Let me talk about ways to improve gray hair 1. Not picky eaters will cause melanin synthesis obstacles in the body, if you can not make melanin hair will be white. It is recommended to eat chicken, lean beef, pork tenderloin and other foods rich in tyrosine, these foods are raw materials for the production of melanin in hair. You can usually treat nuts as snacks: walnuts, peanuts, hazelnuts, you can also eat more black beans, yam, Poria, black sesame, these foods are rich in nutrients can make hair grow better. You can also eat kelp, seaweed, and shellfish rich in iodine, which can improve the yellowing and dryness of the hair and make the hair shiny. The main component of hair is keratin, eat more high-quality protein foods: soy products, dairy products, fish, eggs can form a variety of rich amino acids into the blood to supplement the hair root nutrition. Lack of vitamin B can also affect hair health. When eating rice, you can mix coarse grains in the rice, such as black beans, brown rice, purple potatoes, sweet potatoes and other vitamin B supplements. Eating a balanced diet is the foundation of good health. Don’t be picky! 2. The lack of proper exercise will result in poor blood circulation, which will prevent the blood from being transported to all corners of the scalp, and the melanocytes will not function properly. Proper physical exercise can accelerate the body’s blood circulation and keep the black cells functioning normally. Aerobic exercises such as running, skipping rope, and swimming are all good exercises that can help the body’s blood circulation to accelerate, so that the head blood circulation can be smooth, and the hair can better absorb nutrients. 3. Maintain good living habits The majority of “less white heads” appear mainly in junior high school and high school, and are more common in the back of the brain. Apart from genetic factors, poor living habits may be the main reason for inducing less white heads.  So go to bed early and get up early, do not stay up late, lack of sleep will also lead to insufficient melanin secretion, to ensure that sleep for 8 hours a day. 4. Good mentality In a research survey, it was found that white-haired people are more introverted, and mentality is also the reason for “less white heads”. Pay attention to staying in a happy mood, don’t worry too much about life, and live in the present moment. It’s okay to brush up hilarious variety shows or TV shows and adjust your mood. 5. Long-term exposure of the hair to the sun with UV rays, reactive oxygen radicals (ROS) will accumulate continuously in the scalp, and induce oxidative stress, which will cause the ectopic differentiation of hair follicle stem cells, which will affect the entire pigment formation process White hair appears.  When the sun is strong, you must do a good job of sun protection for your hair, go out and wear a hat or umbrella to protect it at any time, to avoid the damage of ultraviolet rays. 6. Go to the dermatology department of the hospital in time. There is a sudden increase in white hair and it has not been improved for a long time. You should go to the dermatology department of the regular hospital to check whether it is caused by pathological reasons, and follow the doctor’s instructions for medication. 7. Misunderstandings in the treatment of white hair Do not use Polygonum multiflorum to treat white hair yourself! The effect of Polygonum multiflorum on white hair is currently not supported by rigorous scientific research, but it is suggested that the toxicity of Polygonum multiflorum to liver is clearly published in the announcement of the State Drug Administration. There is also a lot of news on the Internet about the poisoning of Polygonum multiflorum. So I tell you here, don’t use Polygonum multiflorum to treat white hair, and don’t take your life as a joke. To ensure a reasonable diet, proper physical exercise, and adhere to the daily routine of going to bed early and staying up late, there is a certain chance that white hair turns to black hair.
