Because of all kinds of reasons, some people always lose their hair and have little hair, especially in summer, which is very serious. Why? What's the cause? Let's take a look
1、 Exposure to the sun
One of the reasons why hair loss is more serious in summer than in the other three seasons is the influence of external environmental factors. In summer, the sun is strong and the ultraviolet rays are strong. When the ultraviolet rays are directed on the head, it will stimulate the skin on the head of the human body, resulting in the phenomenon of hair damage and falling off.
Therefore, in summer, we should protect our heads and less activities in the sun. When we go out, we'd better wear a sunshade hat or umbrella to protect our hair from the sun.
2、 Excessive consumption of cold drinks
Cold drinks can cause hair follicles to contract suddenly, according to the latest research. If you eat too much ice cream, soda and other cold drinks, it will have a bad impact on the hair follicles that need a lot of sweat and heat dissipation in summer. This is also one of the important reasons for more serious hair loss in summer. However, many people like to eat cold drinks are particularly easy to ignore this point.
Therefore, in order to maintain your hair in summer, you should bear to eat less cold drinks and drink more warm water!
3、 Cold and warm air conditioning
More and more people lose their hair. In addition to staying up late frequently, irregular work and rest, and high pressure of study and work, the cold and warm air conditioning is also one of the important reasons for more serious hair loss in summer. In summer, when people are in the environment of air conditioner dehumidification for a long time, the moisture of hair will be gradually drained, so that the hair will become dry, easy to break and easy to fall off.
4、 Bleach in the pool
In the hot summer, many people will choose swimming to relieve the heat and exercise. However, the water in the pool may contain chlorides from bleached pool water, which will damage our hair and cause hair loss.
Therefore, after swimming, pay attention to wash and care for hair.
5、 Inadequate protein supply
Protein, as an important substance necessary for hair production and nutrition, usually the protein content of meat food is relatively high. However, due to the hot and dry weather in summer, people tend to eat light appetizers, and the consumption of meat food is relatively reduced. If people don't get enough protein, hair loss will be more serious.
Therefore, in summer, we should eat more foods with high protein content, iron, calcium and vitamin A, which can nourish hair, such as eggs, lean meat, fish and sesame.
6、 Frequent inflammatory stimulation
If the scalp has folliculitis, yellow ringworm or other boils, carbuncle and other symptoms, it will make the hair foundation unstable, easy to cause hair loss. In summer, when the sun is shining, people sweat like rain, and there is a lot of dust, bacteria and viruses multiply rapidly. It is difficult to clean the hair thoroughly. There is a risk of skin diseases on the head. In case of such diseases, the hair will fall out more seriously.
Therefore, you should wash your hair frequently in summer. When shampoo, can massage scalp with fingertip to promote blood circulation of head, prevent scratching scalp with fingernail.
