Sweet foods produce a large amount of acidic substances during metabolism in the body, which hinders hair growth. The high thermal energy generated by the breakdown of sugars can cause the sweat and sebaceous glands to secrete excessively, and lead to the accumulation of subcutaneous fat, which can easily cause seborrheic dermatitis and subsequently trigger seborrheic alopecia.
Consuming excessive amounts of oil can easily lead to poor fat metabolism, causing fat to thicken. At the same time, the metabolic process of fat also produces acidic substances, affecting the blood's pH balance and being detrimental to hair growth. Therefore, people prone to hair loss, especially those with seborrheic dermatitis and seborrheic alopecia, should preferably eat less greasy food.
Spicy foods can deplete vital energy and body fluids, generate heat, and stir up "wind," which can easily cause hair to lose its moisture, become dry and brittle, and fall out easily. For patients with hair loss due to liver and kidney yin deficiency and a constitution that tends to be "hot," spicy foods are like adding fuel to the fire, accelerating hair loss.
