In the summer, we are more sensitive to the effects of ultraviolet rays, such as sunburn. However, it is not until the season before summer that UV rays become more intense.
The effects of UV rays are not limited to the skin. A good UV protection can also prevent gray hair.
What are the months and times of the year when the UV rays are really strong?
In general, there is an impression that ultraviolet rays are stronger in mid-summer. In reality, however, UV rays are strongest between May and September. In fact, it is too late to start UV care in summer.
In terms of time, the amount of UV rays is highest between 10:00 and 16:00, with a peak around 12:00. Even on rainy or cloudy days, UV rays reach the ground, so be on your guard and take UV protection measures.
Is UV light badass?
Excessive exposure to UV rays not only causes sunburn, but also has many other negative effects. Exposure to strong UV rays causes cells to produce reactive oxygen species (ROS), which accelerate the aging process. This is why sunburn marks can become wrinkles or spots. Hair is no exception. Exposure of the scalp to ultraviolet rays slows down the function of hair matrix cells, causing hair loss and graying.
On the other hand, UV rays are necessary for living organisms. Exposure to UV rays causes the body to produce vitamin D.
Vitamin D is always necessary for the production of calcium, so UV rays are also essential for a healthy body. Recently, UV protection has become too advanced, and some people are suffering from vitamin D deficiency.
Effects of ultraviolet rays on hair
The term “photoaging” is used to describe the aging process. It refers to the aging process caused by exposure to light.
The most obvious effect on hair is sunburn. When hair is exposed to large amounts of UV light, it destroys the melanin (pigment) inside the hair. When you spend all day outside in the middle of summer, your hair turns brown, which is caused by the UV rays destroying the pigment in your hair.
The effects of ultraviolet rays also reach the cells, which can damage the hair follicles and cause gray hair to grow. The pigment cells called melanocytes in the hair follicles within the hair follicles are damaged by UV rays and are unable to color the hair.
This is precisely the photoaging that occurs as a result of exposure to ultraviolet radiation.
Start taking action as soon as possible.
Just as you apply sunscreen to your skin, you need UV protection for your hair! These days, there are UV-protective sprays and milks for hair. You can use them quickly before going out. To protect your scalp, we recommend applying a lotion for scalp (such as lotion) after shampooing, just as you would apply lotion after washing your face.
As soon as May arrives, it is necessary to wear a hat or parasol when going outside. Recently, hats and parasols made of UV-cut materials are available, so it is a good idea to use them.
It may also be a good idea to avoid going out at noon and to go out in the morning or evening as much as possible.
Ultraviolet rays that have always been there.
UV rays are not seasonal and are basically present all year round. The only strong period is from May to September, so one should not let one’s guard down even in winter.
A parasol in winter is out of season, but a hat can provide both protection from the cold and UV rays, so take care of your hair and scalp with year-round UV protection.
