The number of gray hairs that increase year by year may be a source of concern for many people.
"I don't want to get any more gray hair!"
Even if you think so, you don't know what to do. Also, in spring and summer, there are different causes of gray hair than usual, so you can't go wrong with prevention and care.
Therefore, this time we will introduce the causes of gray hair as well as hair care that you should be especially careful about in spring and summer.
2. What causes gray hair to increase in spring and summer?
causes of gray hair
First, let's take a look at what causes gray hair to grow.
Heredity
Those who have gray hair from a young age, and those who have less gray hair as they age, are thought to be inherited through genetics. Although this is an area that is not yet fully understood, statistics suggest that information about melanocytes, the cells that give hair color, is inherited.
If you have parents or grandparents who have a lot of gray hair or gray hair prematurely, you may have inherited similar characteristics.
Ageing
It is no exaggeration to say that the number one cause of gray hair is the increase in gray hair due to aging. As hair grows, cells called melanocytes produce the pigment melanin to give hair its color, but as we age, the function of melanocytes declines.
If melanocytes do not function properly, hair will lose its color and gray hair will increase. Another cause is that as we get older, blood flow tends to deteriorate, making it difficult for nutrients to reach the scalp.
nutritional imbalance
Nutrients ingested through food are carried and distributed through the bloodstream, allowing the scalp and hair to grow healthily. However, if this nutrition is disrupted, the hair will lack the nutrients it needs, leading to various problems such as gray hair and thinning hair.
Hair requires nutrients such as protein, minerals, and vitamins, and these are nutrients that you should be especially conscious of consuming.
You need to be careful because if you only consume foods that are high in fat and sugar, the scalp will secrete too much sebum and the scalp environment will be disturbed, which can lead to gray hair.
stress
Humans use the autonomic nervous system to control the movement of blood vessels, etc., and this is done by alternating between the parasympathetic and sympathetic nervous systems. When you feel stressed, the sympathetic nervous system becomes dominant, causing blood vessels to constrict and blood flow to deteriorate.
Conversely, in a relaxed state, the parasympathetic nervous system becomes dominant and has the effect of widening blood vessels and promoting blood flow. When the sympathetic and parasympathetic nervous systems work together in a moderate manner, the mind and body are in a good state of balance.If you are under too much stress, the sympathetic nervous system will remain dominant for a long time, resulting in poor blood flow.
Nutrients necessary for hair are carried through the bloodstream, so if the blood flow is poor, nutrients won't reach the scalp and hair roots, which can lead to gray hair and stunted hair growth. You need to be careful because it can lead to not only gray hair but also thinning hair and hair loss.

What causes gray hair to increase in spring and summer?
Now that we know the main causes of gray hair, we will also take a look at the causes of increased gray hair in spring and summer.
UV
It is said that UV rays are the enemy of the skin, and many people apply sunscreen on their face and body to protect themselves from UV rays, but unfortunately in many cases they do not protect their scalp and hair from UV rays. That's the reality.
Exposure to ultraviolet rays causes photoaging of the scalp, just like the skin. Ultraviolet rays are divided into UV-A, which has long wavelengths and can reach the dermis, causing spots and sagging, and UV-B, which has short wavelengths but causes inflammation on the surface and damages the scalp and hair. I am.
Both of them place a heavy burden on your scalp and hair and can cause a lot of damage, but you should be especially careful about UV-A, which has a long wavelength.This nutrition reaches the hair matrix cells and melanocytes, which are responsible for the production and coloring of hair, and may impede the production of healthy hair.
UV-B is a strong source of damage to the hair itself, so if you are outdoors for a long time, you need to be careful and take precautions against both.
cold scalp
In the summer, there are many situations in which your scalp tends to get cold, such as when you leave your hair wet for too long because it's hot after using the air conditioner or taking a bath. When the scalp gets cold, blood flow to the scalp worsens, making it difficult for nutrients and oxygen to reach the scalp.
There are many capillaries running under the scalp, which deliver nutrients and oxygen through the hair roots, so blood flow to the scalp is essential for healthy hair growth.
Be careful of pollen
Pollen tends to be a blind spot. If you have hay fever, you will take measures to protect the areas where symptoms appear, such as wearing a mask or using eye drops, but most people do not do anything about their scalp and hair.
Hair is also a part of the body that is prone to static electricity, making it easy for pollen to adhere to it. This makes it easier for pollen to adhere to your scalp,People who are prone to allergic reactions to pollen may experience symptoms such as inflammation and itching on their scalp.
If you leave it as it is, the scalp environment will deteriorate, which may inhibit hair growth and lead to thinning hair or gray hair. If you are not allergic to pollen, you don't need to worry too much about it, but if you are not, you need to be careful.

We will also introduce recommended care that you can take to prevent gray hair from increasing.
Review of lifestyle
Your daily lifestyle habits not only affect your health, but also your scalp and hair. So please pay attention to the lifestyle habits that you usually do without thinking.
・A well-balanced meal
When we get busy, we tend to rely on convenience stores and fast food, but if we choose the wrong foods, we end up with an unbalanced diet that is high in fat and sugar.
Meals high in fat and carbohydrates are not good for the scalp environment as they can cause excess sebum secretion on the scalp and cause it to become sticky.Hair especially needs nutrients such as vitamins, proteins, and minerals, so be conscious and actively consume them.
Vitamins…kiwi, nuts, spinach, broccoli
Protein…Fish, pork, eggs, dairy products
Minerals…seaweed, shellfish
・Moderate exercise
It's easy to think that exercise equals intense exercise, but even something as light as you can do can be very effective. Promoting blood flow through methods that do not put stress on the body, such as walking or yoga, will improve blood flow to the scalp, ensuring that oxygen and nutrients are distributed properly, which will have a positive effect not only on the scalp environment but also on hair growth. It also helps prevent.
Start by doing things you can do, such as actively using the stairs or walking one stop after work.
・Good quality sleep
If the quality of your sleep deteriorates, you will not be able to benefit from the hair growth hormone that is secreted in large quantities while you sleep, and lack of sleep will cause poor blood flow, which can have various negative effects. I'm coming.
Before going to bed, turn down the lights a little and avoid using your cell phone or computer to avoid exposure to blue light.The appropriate bedtime will vary from person to person, but try adjusting your bedtime so that you can sleep for 22 to XNUMX hours and go to bed between XNUMXpm and XNUMXam, when growth hormone secretion is at its peak.
UV protection
Care that protects not only your skin but also your scalp and hair from UV rays is essential, especially from spring to summer when UV rays become stronger. Physical protection such as hats and parasols is also effective in protecting against UV rays. It will be even more effective if both your hat and parasol have UV protection.
For those who don't want to wear hats or parasols, we recommend that there are many sunscreens available in the form of a spray, which can easily protect you from UV rays by simply swishing them on.Since you can reapply it on the go, it also has a high UV protection effect.
Scalp shampoo & treatment
Dirt that cannot be removed with regular shampoo gets stuck in your pores. If you leave it as is, it may cause disturbance to the scalp environment. It's a good idea to have a regular head spa at a beauty salon to reset the dirt, but it's also effective to use a scalp shampoo and treatment to prevent daily dirt from building up.
