When gray hair grows, it stands up and becomes thick and strong.Some people may feel that it grows faster than black hair.
However, in reality, there is no significant difference in the speed of growth.There are differences in the characteristics of the hair depending on the ingredients.
Therefore, I would like to explain in detail the difference between black hair and white hair.Why do gray hairs grow faster?If you are thinking about it, please refer to it.

1. What is the difference between black hair and gray hair?
First, let's take a look at the difference between black hair and white hair.By knowing the difference, you can also understand the characteristics of gray hair at the same time.
different ingredients
The big difference between white hair and black hair is the difference in ingredients.Hair is made up of protein, water, and lipids.
このThe amount of lipid is characterized by less than black hair compared to gray hair.Also, the amount of squalene and metals is similarly reduced.
These differences are known to affect the development of hair color.
Gray hair is thicker and stronger
Black hair contains melanin, which gives it color as it grows, but gray hair does not contain melanin.At this time,Gray hair grows with a lot of keratin protein instead of melanin.
This keratin protein is highly water repellent, so gray hair becomes stiffer.It is for this reason that gray hair gives a thicker and stronger impression.
In addition, the high water repellency is also a problem, making it difficult for perm and color chemicals to react.
There is no process to make black hair
As I mentioned earlier, when black hair grows, it contains melanin pigment and grows with color.but,Gray hair has the impression that it grows faster than black hair because there is no process to add this color.
Due to fewer processes, gray hair is stronger than black hair because it has a lot of power to grow and you can concentrate only on growing.
2. It's not actually growing fast
So, do gray hairs really grow faster?According to Shiseido's research results, "white hair grows faster than black hair (average comparison)." (Reference: About the latest findings from research on gray hair at Shiseidohttps://corp.shiseido.com/jp/newsimg/archive/00000000000470/470_n0m42_jp.pdf ）
However, the "average value" of black hair is one of the keys, and the growth rate of black hair includes various stages of hair, such as downy hair and newly grown hair.From this, when studying with the average value of white hair and black hair,In fact, it is said that there is not much difference in growth rate.
3.Is there a way to slow down the progression of gray hair?
Still, gray hair has a negative image of looking old and tired just by looking at it.Here are some ways to slow down the progress.
If you take measures to reduce the progress speed even a little, it will be easier to clean, so please refer to it.
diet improvement
First of all, let's increase melanin pigment to make energetic black hair.It is recommended that you take in a component called "tyrosine" that is the source of black color.
Tyrosine is abundant in cheese, nuts, soy foods, etc., so be sure to include it in your diet.
Scalp massage
Scalp massage is also effective to activate the melanocytes in the back of the scalp.Scalp massage will promote blood circulation and help nutrients reach the areas where they are most needed.
What I want to focus on here is "friction".Be careful as friction may damage your scalp.
If possible, if you go after shampooing, or use serum or oil to smooth the slide, you won't have to worry about it getting damaged.
do not accumulate stress
Accumulating stress is bad for your hair as well as your body.When blood circulation is poor due to stress, the nutrients necessary for hair cannot reach melanocytes.
First of all, let's try to get a good sleep and light exercise so that the fatigue of the day does not accumulate.Even light exercise will leave your body refreshed and relaxed.
If the body is relaxed, the balance of the autonomic nervous system will be balanced and the work of melanocytes will become active.
Create time away from your smartphone or computer
In modern society, smartphones and computers are indispensable.However, it is also important to spend some time away from your smartphone or computer.
If you spend all day looking at your smartphone or computer, you will become irritated, and it is said to be a "modern disease."In addition, symptoms such as eye strain and stiff shoulders may appear.
These symptoms affect the body in various ways, such as poor blood circulation, and nutrients do not reach the hair.Therefore, people who live a life where they cannot leave their smartphones or computers should be careful.
4. Revitalize the scalp and regain black hair
I explained about the growth speed of black hair and gray hair.It turns out that gray hair has the impression that it grows quickly because there is no thick coloring process.
However, in reality, there is not much difference in growth speed.Therefore, let's try to keep your scalp healthy first.
Gray hair isn't like going back to black hair anytime soon.Be persevering, make your scalp environment and make an environment that is hard to grow gray hairs!
