In winter, the wind is heavy and the dust is heavy. Especially in today's increasingly polluted era, when the hair is blown and invisible, the microbes and dust in the hair above the head are like the gravel on the sandpaper. Raging on the scalp, increasing the friction between the comb and the hair and hair as you brush your hair and move. Microorganisms that are invisible to the naked eye may cause bacteria on your scalp, and even cause hair follicle infection, which directly affects the living environment and quality of hair.
The friction causes the hair on the surface of the hair to rise, and the surface of the hair becomes rough. In severe cases, the hair is split and broken. At this time, wearing a comfortable and stylish baseball cap is tantamount to wearing a beautiful and protective outerwear for the hair, effectively blocking the invasion of dust and microorganisms.
The head is called "the sink of all the sun." Medical research has found that people who do not wear a baseball cap at rest have a heat loss of 30% of the total body heat and 60% of the total heat at 4 °C when the ambient temperature is 15 °C. If the head is cold, it will cause cerebral vasoconstriction, which may cause dizziness, headache, or dysfunction of the scalp and metabolic disorders of the hair follicle, resulting in imbalance of hair nutrition or unnatural hair loss. It can be seen that in the cold winter, the head and other parts of the human body need to be warm and cold.
