Alopecia universalis
Introduction
Introduction The beginning of hair loss is one or several round or elliptical hair loss areas with clear boundaries, which are about 1 to 2 cm larger. There are often loose and easy-to-remove hairs at the edges of the hair loss area, some of which have been broken, and the hair at the proximal end tends to shrink. If the hair is pulled out, it can be seen that the hair is thick and thin like an exclamation mark (!), and the lower hair pigment is also lost. As hair loss continues to increase, each piece expands and merges to form an irregular shape. If you continue to progress, you can be completely bald. In severe cases, eyebrows, eyelashes, manes, pubic hair, and body pubes also fall off to form a baldness.

If hair loss is not much, but the hair grows very slowly and the hair becomes thinner, it is called pathological hair loss.
There are many factors leading to pathological alopecia, both congenital or hereditary factors, as well as acquired factors; both physiological and pathological causes. However, acquired factors, that is, some pathological factors caused by hair loss are most common, such as some mental stress, acute and chronic infectious diseases, various skin diseases, endocrine disorders, physical and chemical factors, neurological factors, nutritional factors, etc., can lead to hair loss.
