Seasonal hair loss usually occurs from August to November, and seasonal hair loss usually means hair loss in the fall and winter seasons. After the change of season from August to November, the temperature finds a significant change into the fall and winter seasons. The weather is dry and cool, which accelerates the evaporation of water from the mucous membrane of the scalp, leading to a decrease in the secretion of sebaceous glands, and ultimately causing the hairs to dry up and fall out. After August, the temperature drops significantly, and the temperature of the scalp also changes, causing the scalp’s vascular network to enter an inactive state. The supply of nutrients to the scalp mainly relies on the scalp’s vascular network, and the inactivity of the scalp vascular network leads to insufficient supply of nutrients to the scalp and eventually causes hair loss. Seasonal alopecia patients should reduce or avoid spicy and stimulating foods in daily life, eat more fresh fruits and vegetables, and ensure sufficient sleep, avoid excessive fatigue, late night and other bad habits, for the relief of seasonal alopecia has a more positive significance. If hair loss is more serious, you should seek medical treatment in time.
