Why do I start losing hair when the weather gets hot?

In hot weather, metabolism speeds up and hair loss is more obvious. This is a normal phenomenon. The alternation of hot and cold and seasonal changes can cause hair loss.

General causes of hair loss are:

1. Increased hair loss often occurs when mental stress is too great.

2. Hair growth is affected by a variety of endocrine hormones, so when endocrine abnormalities occur, hair loss diseases are often caused, the most common ones being trichotillomania and androgenic alopecia.

3. Hair is an external manifestation of physical condition. Malnutrition and abnormal metabolism of the body can cause changes in hair quality and color. Severe malnutrition can even lead to diffuse hair loss.
