Can scalp cause?
Severe sun damage to the scalp can lead to hair loss. Long-term UV exposure can damage scalp hair follicles and lead to increased hair loss. So it is essential for both men and women to do a good job of protecting their heads from the sun. If guys find it inconvenient to go out with an umbrella, they can wear a sun hat or use a hair sunscreen spray to prevent sunburn.
Why does the sun still cause hair loss
Poor sun protection will double the rate of skin aging. The scalp is the second thinnest skin on the body and ages 6 times faster than the face and 12 times faster than the body skin, secreting twice as much oil as the skin on the face. Unlike the 28-day metabolic cycle of normal skin cells, the metabolic cycle of scalp cells is only 14-21 days. Scalp aging not only accelerates the sagging of facial skin, but worse, if the scalp is sunburned, the good days of hair are numbered.
Hair is made up of keratin cells, most of which are keratin. Keratin is made up of a long chain of amino acids containing about 20 amino acids, most of which are cystine. When exposed to sunlight, the cystine in hair absorbs UV rays and protects the scalp.
However, when cystine absorbs a large amount of UV light after exposure to sunlight, it breaks its disulfide bonds and decomposes, the keratin in the hair denatures and breaks, and the hair loses its original moisture and nutrients. In summer, strong UV rays reduce the physical resistance of the hair, hinder the chain binding of proteins in the hair, making them break, causing the hair scales to buckle and fall off, which in turn makes the hair fragile and breakable. At the same time, UV rays cause water loss from the scalp and reduce water control, leading to dry, short hair. Also, summer is hotter and easier to sweat, which tends to build up a lot of sweat at the roots of the hair. If cleaning is not complete, a large amount of dirt and bacteria will accumulate in the hair follicle area of the scalp for a long time, causing itchy scalp.
So whether it is men or women, good head sun protection is very necessary. If guys feel inconvenient to go out with an umbrella, you can wear a sun hat or use a hair sunscreen spray to prevent sunburn. In addition, the self-repair process of sun-damaged hair is very difficult and requires an adequate supply of nutrients from outside and proper repair to minimize damage to the hair.
What to do after sunburned hair
If your hair is sunburned, try trimming the sunburned hair. If your hair is severely sunburned, you should cut it all off and take good care of it.
