"I wanted to grow old with you, but I didn't expect to have a white head first."
This passage reflects the general situation of young people with gray hair. CCTV has also reported that now, more and more young people are beginning to grow white hair.
Why are people not old and their hair is white?
In fact, this is a disease, Western medicine calls it premature leukoligansis, commonly known as "less whitehead", there are two major types, one is congenital less whitehead, the other genus is acquired less whitehead.
Hu Zhiqi, director of the Department of Plastic surgery and beauty of Nanfang Hospital of Southern Medical University, pointed out to the 21st Century Business Herald reporter that white hair is mainly the progressive loss of melanocyte tyrosinase activity in hair follicles, which gradually disappears from the melanin in the hair shaft. Risk factors for the development of gray hair include increasing age, heredity, and increased gray hair due to stress or nutritional imbalances.
So how should gray hair be prevented? Hu Zhiqi pointed out that the current treatment method is still focused on enhancing nutrition and improving mental state, and it is also crucial to appropriately increase the intake of B vitamins in daily life, exercise appropriately, and maintain a happy mood.
With the increasing number of silver-haired people, the market size of the hair dye industry is also expanding. According to the China Commercial Industry Research Institute, the market size of the mainland hair coloring industry will exceed the mark of 20 billion yuan in 2021, growing to 21.4 billion yuan. Among them, consumers prefer green and natural hair coloring cream.
How did "less whiteheads" come about? How can it be prevented?
Juvenile white is a childhood and adolescent leukotic disease, Western medicine called premature leukotic disease, its etiology is very complex, there are two major types, one is congenital less whitehead, the other genus acquired less whitehead.
Congenital less whiteheads are mainly caused by genetic factors. Yang Shuxia, chief physician of the Department of Dermatology at Peking University First Hospital, also said that genetic factors are one of the important factors that cause less whiteheads. It is reported that less whiteheads belong to autosomal dominant genetic diseases, which can be understood as familial juvenile whiteheads. In addition to simple early white hair, patients may be accompanied by excessive sweating of the palms and soles of the hands and feet, hypoplastic molars, or loss of bisceral teeth.
Hu Zhiqi pointed out to the 21st Century Business Herald reporter that white hair is mainly the progressive loss of tyrosinase activity of melanocytes in hair follicles, so that the melanin in the hair shaft gradually disappears. Risk factors for the development of gray hair include age, genetics, mental health, and nutrition.
In fact, the most common cause of gray hair is a physiological factor. As the age increases, all organs of the body will gradually decline, and the first to decline is the skin hair follicles, and the number of melanocytes in the skin hair follicles will decrease with age.
Among them, the synthesis of melanocytes is directly related to the color of the hair. In general, the more melanin, the darker the hair color will be. If once melanin cannot be synthesized normally, the hair cannot turn black, and white hair appears. In fact, this is also the natural law of the human body.
Hu Zhiqi also pointed out that the increase in gray hair in young people may be related to mental stress or unbalanced nutrition.
Studies have found that overload stress does lead to the development of gray hair. It is reported that mental factors are essential for the synthesis of melanin in hair. If people are in a state of mental stress, excessive brain use, anxiety and anxiety for a long time, the blood vessels that supply hair nutrition will contract, which will hinder the function of melanin production in the hair nipples at the root of the hair, affecting the synthesis and transportation of melanin.
Even if melanin can be produced, but due to a certain degree of disruption of the brain blood circulation and internal environment, the input channel is blocked, a large number of gray hair can be produced in a short period of time, and the phenomenon of "one night sad whitehead" may occur, but when the pressure is relieved, the white hair may be relieved.
In addition, if the nutritional deficiency can also lead to an increase in white hair. For example, a lack of vitamin B in the body may lead to the tendency of young people to grow gray hair. It is reported that the color of hair is often related to melanin in the body, and the main component of melanin is vitamin B group, so when we lack vitamin B in the body, this nutrient will not only make our entire body's metabolic capacity decline, but also lead to a decrease in melanin in the body, resulting in an increase in white hair.
Trace elements such as copper and iron will also affect the synthesis of melanin, and studies have found that the content of trace elements such as copper and iron in black hair, light hair and white hair is reduced in turn. When the human body lacks copper, the hair color will become lighter and whiter; when the human body lacks iron, the metabolism will be blocked, and the synthesis of melanocytes will also be reduced, which may cause symptoms such as hair whitening and large-scale hair loss. Therefore, people need to eat more foods rich in copper and iron, such as animal liver, spinach, pig blood, seafood and so on.
So how to prevent the development of white hair? Hu Zhiqi reminded that eating black foods such as black sesame seeds and black beans cannot treat gray hair. Current treatments still focus on enhancing nutrition and improving mental status. "The intake of B vitamins, such as vitamin B6, can be appropriately increased in daily life, as well as the intake of protein and vitamins (eggs, lean meat, fresh vegetables), smoking cessation and alcohol restrictions. In addition, proper exercise and keeping a good mood are also crucial. ”
"Plant hair coloring" has become the development trend of the industry
Hu Zhiqi pointed out that white hair is generally not reversible. In recent years, with the acceleration of the pace of social life, the number of silver-haired people caused by pressure has gradually increased, and the market demand for hair dye products will grow day by day.
With the continuous heating up of the "beauty economy", makeup and hair will become the next "beauty economy" depression. According to the data, the market size of China's beauty salon industry has reached 368.5 billion in 2020, of which the size of the hair coloring market has reached 18.2 billion, and it is showing an upward trend year by year. According to the China Commercial Industry Research Institute, the market size of the mainland hair coloring industry will exceed the mark of 20 billion yuan in 2021, growing to 21.4 billion yuan.
The 21st Century Industry Research Institute pointed out in the "2019 Double 11 High-quality Consumption Report" that the demand of silver-haired people in the fields of hair care, hair coloring and other segments is increasingly strong; the Kantar Consumer Index also shows that in the personal care category, hair products account for 24% of the spending of silver-haired people, and have a double-digit growth of 10%, higher than the overall growth rate.
According to the iResearch survey, the per capita annual hair care consumption in the mainland is mainly concentrated in 4000-6000 yuan, and the "2021 China Medical Maintenance Service Market Analysis Report - Market Status and Development Trend Forward" also pointed out that 43.3% of customers visit the store on average once a week, and 75.2% of customers average once every two weeks.
From the classification point of view, hair dyes can be divided into temporary, semi-permanent, permanent hair dyes. With the development of the industry, the mainland has also launched a variety of colored hair dyes, and the number of industry participants has gradually increased. Among them, L'Oréal Paris, Schwarzkopf and Weina Wella occupy a large market share with their technical advantages.
But whether dyed hair will hurt the scalp also raises concerns. Professor Yang Qinping, chief physician and doctoral supervisor of the Department of Dermatology of Huashan Hospital affiliated to Fudan University, once told the 21st Century Business Herald reporter that perm dyeing mainly destroys the structure of hair shafts, and moderate perm dyeing can be recovered by itself after a certain period of time, but if the frequency is too high, such as some women 1 or 2 months to perm dye, the chemicals of hair dye will destroy the hair shaft, and will also have a certain impact on the scalp. Therefore, it is recommended to be moderate, and to use hair coloring products produced by regular manufacturers to ensure safety.
Yang Qinping said that for scalp problems, we must establish the concept of active medical treatment and early diagnosis, and have a positive attitude when treating, adopt scientific methods, and adhere to long-term treatment. Don't covet convenience, buy some "IQ tax" products from the Internet, both waste money and delay the disease.
It is understood that at present, domestic and foreign hair dye brands are mostly based on "plant hair dyeing", starting from the concept of health and safety, adding many natural plant ingredients in the hair dye advertisement to meet consumers' demand for green and natural hair dyeing paste; in addition, whether there is a pungent odor is also one of the important criteria for consumers to judge the health and safety of hair dye products.
In fact, the concept of plant hair coloring has been in the attention of international brands such as L'Oréal as early as four or five years ago. In 2017, L'Oréal launched the first hair dye Potanea with an all-plant formula as the mainstay, and in recent years, many giants such as Procter & Gamble and Unilever have been increasing the layout of the "plant hair coloring" subdivision track, but each brand uses a differentiated positioning strategy, which is different in the composition, efficacy, form and even taste of hair dye products.
