Personal image What are you most afraid of losing? It must be a flowing hair. Afraid of baldness, white hair, and split ends If one day I suddenly discovered I suddenly have a lot of white hair Absolutely a moment of mental explosion However, don’t panic if you suddenly grow white hair. It may not be because of your age. It may also be due to other reasons, such as the most easily overlooked point - insufficient nutrition. If you want black hair, you must ensure that the melanin in the hair can be synthesized normally. Melanin is produced by melanocytes. If you want it to work hard, you need to provide it with sufficient nutrition. Image source: Photo Network Once certain factors lead to nutritional deficiency or nutrition cannot be delivered to the hair normally, gray hair may grow. Generally speaking, these three nutrients have a greater impact on hair: protein Protein is an important raw material for hair. Keratin, the basic unit of hair, is synthesized by protein. It can be said that your thick hair is the result of protein. If you don’t take in enough protein for a long time, you will easily have gray hair. Not only that, hair quality deterioration, roughness, and yellowing are all related to insufficient protein intake. If this fundamental problem is not solved, no matter how much conditioner you apply to your head, your hair will not get better. In fact, your hair may even become worse due to irritation. Trace elements such as copper, zinc, and selenium If protein is the raw material of hair, then trace elements such as copper and iron are the catalysts of melanin. Melanin is formed when tyrosine forms dopa under the action of tyrosinase and then undergoes oxidation. Therefore, the activity of tyrosinase will directly affect the efficiency and outcome of this process. Image source: Photo Network Trace elements such as copper and zinc can affect the activity of tyrosinase. Once these trace elements are not supplied in sufficient quantity, the activity of tyrosinase will decrease, affecting the synthesis of melanin , which will be reflected on your head as white hair. B vitamins The B vitamins are a large family, including vitamin B1, B2, B3, B5, B6, B12, etc., all of which play an important role in the human body. Image source: Photo Network B vitamins are involved in our body's metabolism. The growth of hair and nails requires their help, and they can also ensure the normal activity of melanocytes. If vitamin B deficiency occurs for some reason, problems such as hair loss, gray hair, and dry hair may easily occur. Image source: Photo Network Of course, in addition to the lack of these nutrients, there are many other reasons that can lead to more gray hair, such as mental stress, genetics, physical illness, etc. Mental stress leads to gray hair, and melanocyte stem cells are the key. Stress activates the sympathetic nerves, and the neurotransmitter norepinephrine is released in large quantities, leading to the rapid loss of melanocyte stem cells. Image source: Photo Network Genetic factors are one of the important reasons why many people have gray hair. If there are relatives in your family who have gray hair early, then you may also have gray hair early. Image source: Photo Network The abnormal increase in gray hair caused by disease is another issue that needs special attention. Abnormal thyroid function, pernicious anemia, impaired pituitary function, autoimmune diseases, etc. may all be causes. Some congenital metabolic defects, such as tryptophan oxygenase deficiency, methionine malabsorption syndrome, cystine deficiency , etc., can also cause juvenile gray hair. Image source: Photo Network There is no need to worry about this, as gray hair has nothing to do with whether you pull it out or not. The growth of white hair depends on the hair follicles. If only one or two white hairs appear and there is no increase for a long time, it may be that these hair follicles are a little different and it is not a big problem. Normally, these unusual follicles have little effect on other follicles. Image source: Photo Network There is another possibility, that is, those one or two white hairs are just a prelude to growing white hair. You will gradually grow more white hair. Pulling out or not will not stop this process. In comparison, nutritional deficiencies and mental stress are external factors that will cause you to grow more gray hair, which can be alleviated by improving your lifestyle. If you want to keep your black hair longer, try to do the following in your life: ● Ensure a rich and balanced diet to supplement the nutrients needed for hair growth; ● Reduce staying up late and adjust the body's endocrine system; ● Try to avoid excessive UV stimulation to your hair; ● Relieve pressure and give hair more room to grow. Most people have white hair It's a normal process If there is no other problem with the body Don't be so nervous Compared to worrying about how to make it black again It might be better to accept its changes Statement: This article is a medical-related educational popular science article.
