1、 Keeping hair warm and cold: Medical research has found that people who do not wear a hat in a stationary state account for 30% of the total heat lost from the head when the ambient temperature is 15 ℃, and 60% of the total heat lost at 4 ℃. If the head is cold, it can cause cerebral vasoconstriction, and in mild cases, dizziness and headache may occur, Or it can cause disorders in scalp nutrient circulation and hair follicle metabolism, leading to hair nutrient imbalance or a large amount of unnatural hair loss. Severe cases may also trigger the occurrence of some diseases. It can be seen that in cold winter, the head, like other parts of the human body, also needs to be kept warm and protected from the cold.

2、 Dust and pollution prevention for hair: In winter, with heavy sandstorms and dust, especially in today's increasingly polluted era, when hair is blown into a messy and invisible state, the microorganisms and dust in the hair on top of the head are like gravel on sandpaper, ravaging the scalp while increasing the friction between the comb and the hair and hair during daily combing and movement. Those microorganisms that cannot be seen with the naked eye may cause bacteria to grow on your scalp, and even cause hair follicle infections, directly affecting the living environment and growth quality of your hair. Friction, on the other hand, causes the small furry skin on the surface of the hair to curl up, making the surface of the hair rough and even causing it to split or break in severe cases. At this point, wearing a comfortable and fashionable hat is like wearing a beautiful and protective coat on your hair, effectively blocking the invasion of dust and microorganisms.

3、 Sunscreen and radiation protection for hair: Many women who love beauty take fully armed sunscreen measures in summer, especially holding a colorful sunshade umbrella, which not only protects against sun but also exudes charm. However, in winter, they often overlook the power of sunlight and always follow it when walking. In fact, due to the dry and clear air in winter and the high transmittance of ultraviolet rays in sunlight, it is important not to take the winter sun lightly. Excessive exposure to sunlight should still be avoided. So, in order to prevent UV damage, choosing a hat that matches the style and color of the clothing is nothing more than a fashionable and practical clever method.

4、 Constrain hair while reducing its weight.
