Foods that can easily lead to hair loss:
1, polysaccharide food
Sweet food will produce acidic substances during metabolism in the body, which will hinder hair growth. The high heat energy produced by sugar decomposition can make sweat glands and sebaceous glands secrete vigorously, which makes subcutaneous fat easy to accumulate, thus hindering the nutritional supply of hair follicles and easily losing hair.
2, greasy food
Fat is rich in animal fat. Eating too much can easily lead to fat metabolism disorder, subcutaneous accumulation of fat thickening, excessive secretion of sebaceous glands, leading to sebum overflow, affecting hair follicle function and making hair easy to fall off.
The above foods, especially those containing oil in the diet, will block the sebaceous glands of the scalp due to excessive secretion. Excessive intake of pepper will cause dry hair and poor blood circulation through the capillaries of the scalp, leading to a large number of hair loss.
