What Causes Hair Loss?

What causes hair loss?
Hair loss is a problem that many people are concerned about. Some people say that I cannot stop hair loss, but I hope that my hair can grow back after hair loss. So after hair loss, will my hair grow back?

Hair has its own growth cycle. We lose about 100 hairs every day. After the hair falls off, the hair follicles will temporarily stop growing hair, and it will take about three months for new hair to grow.

However, hair loss can be divided into physiological hair loss and pathological hair loss. The one mentioned above is physiological hair loss, which is a metabolic process. Pathological hair loss will cause the number of hairs to fall out to be significantly greater than the number of new hairs, making the hair thinner, so it may be difficult for pathological hair loss to grow back. So what are the common pathological hair loss?

disease caused

Physical disease is a cause of hair loss. The hair loss we usually see may be caused by physical disease, and hair loss is only a symptom of the disease. For example, hair loss caused by problems such as seborrheic dermatitis, extreme kidney deficiency, recovery from a serious illness, malnutrition, etc. Even if the hair loss is controlled, the hair will still not grow smoothly if the underlying problem is not solved. Therefore, if severe hair loss is found, sufficient attention should be paid.
