Revealing the mystery of NMN making hair black and shiny
White hair has always been a problem that troubles many people. It is generally believed that once hair starts to turn white, it means the body sends out a signal of aging.
Not only the elderly, but also many young people pay attention to “big things on their heads” due to their “little white head”. But besides regularly going to a hair salon to dye hair, is there any other way to intervene in the process of hair turning white?

1、 Revealing the Causes of White Hair
1. Genetic factors:
Genetics is one of the main causes of white hair. If there are people in the family who have early white hair, the probability of individuals having white hair will be higher
2. Age factor:
As one ages, the ability of the human body to produce melanin gradually weakens, leading to a gradual whitening of hair. The incidence of white hair usually increases significantly after the age of 40.
3. Oxidative stress:
refers to an increase in intracellular oxidative response, leading to the accumulation of oxides. Oxidative stress can damage pigment cells in hair follicles, leading to white hair.
4. Lead poisoning:
People who are exposed to lead pollution for a long time may experience lead poisoning, which can lead to premature whitening of their hair.
5. Autoimmune diseases:
Certain autoimmune diseases, such as thyroid dysfunction and psoriasis, may cause hair to turn white.
6. Mental stress:
Long term mental stress, emotional instability, and excessive stress may lead to a decrease in melanin production, resulting in white hair.
7. Malnutrition:
Lack of nutrients such as vitamin B12 and copper and iron can lead to a decrease in melanin production, resulting in the appearance of white hair.
The degree of hair blackness determined by the melanin particles synthesized by melanocytes in hair follicles; The more melanin particles, the higher the density, and the darker the hair.
Under normal circumstances, there are abundant blood vessels inside the hair papilla, providing sufficient nutrition for the hair papilla and hair ball, and melanin particles synthesized smoothly.
White hair is a natural physiological phenomenon, although it cannot completely avoided or reversed,
maintaining a positive attitude and a healthy lifestyle, and timely supplementing necessary nutrients such as NMN can improve and delay it.
2、 The Secret of NMN Improving Human Hair Quality
The team of scientists from Harvard Medical School and Professor Ichiro Kanai from Japan have demonstrated in experiments that injecting the enzyme that synthesizes NMN into the blood of young mice into the body of elderly mice can result in dark and dense hair, similar to the effect of hair transplantation.
Research has shown that a decrease in NAD+(coenzyme I) in the body is an important factor leading to white hair,
and NMN is an important substance in the body’s energy cycle (citric acid cycle, also known as the citric acid cycle). Without NAD+, these cycles cannot be carried out at all.
The function of NMN is to increase the level of NAD+, as the gradual decrease in NAD+levels due to age and various external factors can lead to insufficient ATP for hair protein synthesis in hair cells,
ultimately leading to complete loss of vitality of hair cells and the production of white hair.
Supplementing NAD+precursor NMN can enhance the tricarboxylic acid cycle, produce ATP, and give hair cells enough ability to produce hair protein,
thereby promoting protein synthesis in hair, restoring normal melanin production, and turning white hair back into black. At the same time, adhering to sufficient supplementation of NMN can also make hair new, dense, and shiny, reducing hair loss.
NMN, as a novel anti-aging substance, can protect hair health and promote hair growth through various pathways.
