Those who are worried about gray hair
There is still no clear treatment for gray hair. Therefore, the majority of people dye their gray hair to repair it while damaging it. We wondered about this method of treatment and came up with the best solution for gray hair.
We clarify the causes and mechanisms of gray hair from a doctor's perspective, and propose specific measures and effective prevention and treatment methods based on medical evidence and our hospital's track record. If you are worried about gray hair, please read this.
1.Mechanism of hair color
When the mechanism of black hair is normal, melanocyte stem cells differentiate into melanocytes (pigment cells). Due to this action, melanocytes produce melanin pigment, which is deposited on keratinocytes, which are the main constituent of hair, giving hair its color.
2.causes of gray hair
3.Gray hair due to aging
Gray hair associated with aging is said to be irreversible in most cases. Gray hair associated with aging is a phenomenon in which melanocyte stem cells gradually become depleted. This is caused by oxidative stress.
Below is a hair follicle bulb taken from the scalp of the same 64-year-old woman. A is a normal hair follicle that produces a lot of melanin, and b is a hair follicle that has only a small number of gray hair follicle melanocytes and almost no melanin production. The difference between the two is obvious.
[Treatment for age-related gray hair]
The following things have been confirmed in gray hair follicles, so it may be possible to maintain melanin production even after hair turns gray.
Melanocytes do not completely disappear in hair that has turned white due to gray hair, so it is important to delay and prevent hair root aging in order to make use of the melanocytes that survive in the outer hair root sheath. is.
As a specific measure...
4.due to stress
Gray hair mechanism
Some of the melanocyte stem cells normally present in the “bulge” differentiate into melanocytes and produce melanin pigment. When stress is applied, sympathetic nerves are activated, noradrenaline increases, and all melanocyte stem cells in the bulge differentiate into melanocytes. This causes the melanocyte stem cells to become depleted, causing the hair to turn white as there are no more melanocytes to color the hair that will grow back in the next hair cycle. This is the mechanism by which hair turns gray due to stress. (Figure1-b)

[Stress gray hair is reversible]
The experimental results below show that stress gray hair is reversible. In other words, it is thought that melanocyte stem cells have not completely disappeared. From this, we will propose measures that activate melanocyte stem cells and are effective in improving stress gray hair. *The conclusion is the same as gray hair due to aging.
