What causes hair loss

The causes of hair loss are very complex. They are generally caused by the lack of certain trace elements or nutrition in the body. Most people who stay up late for a long time are prone to kidney damage. When kidney function declines, the roots of the hair are no longer firm, causing hair loss. People who often perm or dye their hair will have their hair damaged and are prone to hair loss, so if you want to treat hair loss you must pay attention to all aspects. So what are the causes of hair loss?

First of all, we need to distinguish the types of hair loss. Generally, hair loss can be divided into two basic types: permanent hair loss caused by damaged hair follicles, and temporary hair loss caused by short-term damage to hair follicles. Permanent hair loss is common male pattern baldness. In some European countries, the male baldness rate is as high as 40%.

The hair loss process of permanent hair loss (also known as male pattern baldness) occurs gradually. At the beginning, the hair edge on the forehead shrinks significantly, and the hair on the top of the head is sparse; then it gradually develops and finally develops to only a circle of sparse hair on the back and sides of the head. There are three main reasons for this: genetic factors, lack or imbalance of male hormones in the blood circulation; and being too fat. In addition, scars left by various skin diseases or skin injuries, congenital hair stunting, and severe damage to hair follicles caused by chemicals or physical reasons can all cause permanent hair loss.

Temporary hair loss is often caused by an illness with a high fever. However, X-rays, ingestion of metals (such as thallium, tin and arsenic) or drugs, malnutrition, certain inflammatory skin diseases, chronic wasting diseases, and endocrine disorders can also cause temporary hair loss. There are two treatment options for male pattern baldness. The first is hair transplantation, which involves transplanting hair follicles from the scalp where hair still grows to where hair does not grow, i.e., from the back of the head to the front. The second method is topical application. Regular application of minoxidil can effectively prevent continued hair loss caused by various reasons and promote hair regeneration in bald or sparse hair areas.

1. Seborrheic alopecia: It often occurs in middle-aged and young people, characterized by thick oily secretions on the scalp, shiny, sparse and thin hair, or dry hair, dandruff, dullness, sparse and thin hair.

Solution: Pay attention to eating a light diet, eat less irritating food, eat more fruits and vegetables, or take vitamin B6, B2, etc.

2. Pathological hair loss: mainly due to viruses, bacteria, and high fever that damage hair matrix cells, inhibiting the normal division of hair matrix cells, and putting hair follicles in a state of shock, leading to hair loss, such as acute infectious diseases, long-term use of certain medications, etc.

Solution: Get more rest and your hair will grow back after you recover or stop taking the medicine.
