Does UV cause gray hair?

I think that there are many people who are always careful about UV (ultraviolet) measures for their skin, but do you also take UV measures for your hair?In fact, your hair is exposed to more UV rays than your skin, and if you don't take measures against it, it can cause gray hair.

It is important to take measures for hair in the same way as daily skin care and UV protection.In fact, just paying attention to the little things in your daily life can make a difference.

So this time, we will introduce the relationship between UV and gray hair and measures. If you want to protect gray hair from UV, please refer to it.

XNUMX. There are types of UV

There are three types of UV: UVA (ultraviolet A wave), UVB (ultraviolet B wave), and UVC (ultraviolet C wave).Each feature is as follows.

• UVA (ultraviolet A wave) is the most influential UV to us. Excessive exposure to UVA can cause wrinkles, sagging, and spots.
• UVB (ultraviolet B wave) These ultraviolet rays have the greatest impact on hair because they destroy the melanin pigment.It affects the hair cuticle and can cause dryness and browning of color.
• UVC (ultraviolet C) UVC is absorbed by the ozone layer and does not reach the earth where we are, so it does not have any ill effects.

As mentioned above, skin and hair are affected differently depending on the type of UV.Hair needs UV protection for hair, so I will explain in detail.

XNUMX. What is the effect of UV on hair?

Hair is the part of the body that is most susceptible to damage if it is not protected with a hat or the like.However, most people do not take UV protection.

I will explain what kind of effect it will have on your hair if you do not take measures against UV rays.

(I.e.

Just like your skin, dryness can do a lot of damage to your hair.UV contains ingredients that stimulate proteins, which are the main components of hair.

Due to this ingredient, if the protein is damaged, the water retention capacity will decrease, resulting in dry and stiff skin.

loss of luster

Dry hair cannot repel water because the lipid film on the surface of the hair is oxidized.This is a phenomenon in which the cuticle opens.

If the cuticle is open, it will lose its luster and become squeaky and difficult to pass through.Also, since the hair spreads easily, it may not be neatly put together and it may take time to style.

hair color brown

Hair color is dyed by disassembling the original melanin pigment.For example, melanin pigment is important for keeping hair healthy.Colored hair has less melanin pigment, so even a small amount of UV rays can cause more damage.

As a result, the dye in the hair color becomes the cause of browning when damaged by UV rays.

XNUMX. Relationship between UV and gray hair

I hope you understand a little bit about the effects of UV on your hair.From here, I would like to explain the reasons why damaged hair turns gray.

melanin is destroyed

When melanin is destroyed by UV rays, blood flow is poor and nutrients are not delivered, and melanocytes create hair without pigment.moreover,When the blood flow is stagnant, the scalp becomes dry and hard.

In this way, if there is an abnormality in the scalp, the hair papilla that produces black hair will not function, making it easier for gray hair to form.

damage to hair roots

Ultraviolet rays go beyond the scalp and affect cellular parts such as hair roots.actually,If the melanocytes in the hair root are damaged by UV rays, the cells will not function well.

Cells such as hair roots are affected by UV rays, which is called "photoaging" and causes gray hair.

damage to the scalp

UV, of course, also affects the scalp.In the same way that wrinkles on your skin increase when you notice them, your scalp will deteriorate little by little, causing discoloration and other effects.

in this way,Care must be taken as scalp damage oxidizes sebum, causing dryness and loss of elasticity.

XNUMX. UV protection that you can do before your hair turns gray

Now, let's take a look at the UV measures that you can do yourself before your hair turns gray.You can do it with a little awareness, so please refer to it.

Moisturizing

Moisturizing is important because UV rays dry the skin anyway.Change the shampoo you use every day to one that is hypoallergenic, such as amino acids, and apply a moisturizing serum after shampooing.

It is important to take care of your scalp and hair, which have become delicate due to UV rays, with hypoallergenic items.

Scalp massage

Oxidized scalp becomes dry and hard.Soften the scalp with a massage and improve blood circulation.

In this way, it is recommended to gently massage the scalp when shampooing, as it gently protects damaged hair and removes sunscreen.

get effective nutrients

To keep your hair healthy, nourish your body from the inside out.Protein is the basis of hair.

It is recommended not only to take protein, but also to take essential amino acids at the same time to make effective use of protein.A well-balanced diet can also help prevent gray hair and hair loss.

So remember that a balanced diet is what builds your body and hair.

correct one's lifestyle

Not only the diet but also the right lifestyle is important.No matter how much you pay attention to your diet, lack of sleep and a stressful life can affect your hair.

If you can prepare the environment with good quality sleep and promote blood flow with light exercise, your hair will be beautiful and healthy.

XNUMX. It is important to take measures against UV and keep your hair healthy

You don't look beautiful when your hair is dry.It is also important to take care of your hair with shampoo.

But it's even more important to take care of it before it hurts.A well-balanced diet and a regular lifestyle will not only keep your hair healthy, but your body as well.

UV protection is good not only for your skin but also for your hair, so you can get beautiful and healthy hair.
