Indeed, the cool cold drink ice cream is like a summer redemption, but excessive greedy cold will bring some adverse reactions to the body, and the hair is quietly hurt a little, do you know?
What harm does excessive cold cause to the hair?
1. Inadequate nutrition of hair follicles
Excessive consumption of cold food or drinks can stimulate the intestinal tract, affect the normal diet, then human body nutrients can not be absorbed properly, and over time the body lacks various nutrients, thus hindering the growth of hair, or even getting into the dormant period in advance, gradually falling off.
That's why many people find their hair brittle, yellowing and even losing in the summer. In addition, because of the hot summer, many people will have a bad appetite,the intake of nutrients is inadequate, coupled with cold food, hair follicles get less nutrients .
2. Induce scalp inflammation
Most of the cold drinks are high-sugar, high-fat foods. The high calorie produced by the decomposition of sugars can cause the exuberant secretion of sebaceous glands, and excessive sebaceous secretion can easily cause the inflammation of hair follicles. The appearance of scalp inflammation can lead to metabolic disorders during hair growth and increase the risk of hair loss. So overeating cold drinks in summer can easily lead to increased hair loss.
3. Influencing Hair Nutrient Absorption
Low temperature of air conditioning and excessive cold drinks can cause capillary contraction in the head. Capillary is an important channel for nutrient transport to hair follicles. Capillary contraction will affect the speed of nutrient absorption of hair follicles, and nutrient absorption will become slow, which will accelerate the process of hair loss and hair follicle atrophy.
