Grey hair has always been a problem for many people, it is widely believed that once the hair begins to turn grey, it means that the body sends out a signal of "aging". And not only the elderly, many young people also due to "less white head" attention to "head of the big thing". But apart from running to the hairdresser's regularly for hair colouring, is there any way to intervene in the process of hair turning grey?


I. Reveal the causes of grey hair

The causes of grey hair are very complex and are closely related to age, lifestyle habits, environment, stress and disease, as well as being genetically and hereditarily controlled.

1. Genetic factors: heredity is one of the main reasons for the production of grey hair. If there are people in the family who have early white hair, then the probability of an individual having white hair will be higher.

2. Age factors: with age, the melanin production ability of the human body will gradually weaken, resulting in hair gradually become white. Usually after the age of 40, the rate of white hair will increase significantly. 

3. Oxidative stress: oxidative stress refers to an increase in intracellular oxidation, resulting in the accumulation of oxides. Oxidative stress damages the pigment cells in the hair follicles, leading to grey hair.

4. Lead poisoning: long-term exposure to lead-contaminated environments may lead to lead poisoning, which can lead to premature greying of hair.

5. Autoimmune diseases: some autoimmune diseases, such as thyroid dysfunction, psoriasis, etc., may lead to hair whitening.

6. Mental stress: long-term mental tension, emotional instability, excessive pressure and other situations may lead to reduced melanin production, which triggers white hair. 

7. Malnutrition: lack of vitamin B12, copper, iron and other nutrients can lead to a reduction in melanin production, which leads to the appearance of white hair.

The degree of blackness of hair is determined by the melanin granules synthesised by the melanocytes in the hair follicle; the more melanin granules there are and the higher the density, the blacker the hair. Under normal circumstances, there are abundant blood vessels in the hair papilla, which provide sufficient nutrients to the hair papilla and bulb, and melanin granules are synthesised smoothly.

Many people will choose to dye their hair to cover up grey hair, but hair dyes are after all chemicals, there are allergy-causing phenomena; coupled with the rich blood vessels of the human scalp, often in contact with chemical hair dyes, which will certainly bring harm to other organs of the human body, especially those with a low level of immunity, and is even more unsuitable for hair dyeing.

Grey hair is a natural physiological phenomenon that cannot be completely avoided or reversed, but it can be improved and delayed by maintaining a positive mindset and healthy lifestyle, and by timely supplementation of essential nutrients such as NMN.


II. NMN's secret to improving human hair.

Harvard Medical School scientists and the Japanese team of Professor Ichiro Kanai had experimentally demonstrated that the enzyme synthesising NMN in the blood of young rats, injected into the bodies of old rats, the hair became dark and thick, and the effect was comparable to that of "hair transplantation". The results of this study have been published in the authoritative academic journal Cell, a sub-journal of Cell.

Research has shown that a decline in the body's NAD+ (coenzyme I) is an important factor in the development of grey hair, and that NMN is essential for the reactions of the body's energy cycles (the tricarboxylic acid cycle, also known as the citric acid cycle), which are completely unable to take place without NAD+.

The function of NMN is to increase the level of NAD+, because with the influence of age and various external factors the level of NAD+ gradually decreases, which will lead to the lack of sufficient ATP for hair protein synthesis in the hair mother cells, and finally the hair mother cells will lose their vitality completely, resulting in the production of grey hair. Supplementation of NAD+ precursor NMN can strengthen the tricarboxylic acid cycle, produce ATP, so that the hair mother cells have enough capacity to produce hair protein, thus promoting the protein synthesis of hair, melanin production to return to normal, so that the grey hair becomes black again. At the same time in addition to adhere to a sufficient amount of supplement NMN can also make the hair new hair volume lush and shiny, reduce hair loss phenomenon.

In addition to supplementing with NMN, there are a number of other ways to help keep your hair healthy and promote hair growth. Here are some useful tips:

1. Adjust the diet: to ensure a balanced diet, intake of sufficient vitamin B12, copper, iron and other nutrients, can promote the production of melanin, slow down or prevent the production of grey hair.

2. avoid the use of hair dyes: hair dyes in the chemical composition may cause damage to the hair, so try to avoid frequent use of hair dyes, or choose natural hair colouring.

3. Attention to hair care: Use mild shampoo and conditioner to keep hair clean and moisturised, and avoid frequent use of hot tools, such as hairdryer and curling iron, to reduce damage to hair.

4. Reduce stress: Reasonable arrangement of work and life, learn to cope with stress in a way, such as doing the right amount of exercise, take a relaxing break, can reduce mental stress, help to maintain the health of the hair.

5. Maintain sufficient sleep: sufficient sleep helps the body to recover and repair, and is also conducive to the health and growth of hair.

NMN, a novel anti-aging substance, protects hair health and promotes hair growth through multiple pathways.
